In some specimens the praefrontals form a median suture , whilst in others the frontonasal touches the ])oint of the frontal as in the type from Bongu, Astrolabe Bay. 30. Lygosoma fuscum, D. & B. — Uigo, Ivelesi, Aroma, Bara Bara , Ha veri , Inawi. The extremely numerous specimens from the above localities vary much in the coloration and markings. Some are uniform brown, others olive witii l)luish white spots or ocelli edged with 1>lack, or with large black and white spots or marblings on the sides ; four or six light streaks may be present along the body ; throat sometimes much spotted with dark brown , or nearly entirely black (L. alrogulare, Douglas Ogilby). 31. Lygosoma nigrigulare, sp. n. (PL YII, fig. 3). — Section Liolepisma.

These lizards are very nearly related to A. fiiscum, of which I should have regarded them as a melanotic variety but for the absence of the interparietal shield. 32. Lygosoma bicarinatum, Macleay. — Rigo, Aroma, Hula. Varies much in colour , as pointed out by Douglas Ogilby (Ree. Austral. Mus. I, 1890, p. 93) who has verified the sug- gestion made by me as to the identity of this species with fleieropus alberlisii, Ptrs. & Dor. 33. Lygosoma novae-guineae , Meyer. — Rara Bara, Ha veri. 34. Lygosoma iridescens, Blgr. — Bara Bara. A single specimen , differing from the type in having 24 scales round the middle of the body, 60 lamellae under the fourth toe , and a well-marked light , dark-edged dorso-lateral streak extending from the supraciliary border to the base of the tail. 35. Lygosoma mivarti, Blgr. — Bara Bara, Moroka, Inawi. 36. Lygosoma cyanogaster, Less. — Bara Bara, Haveri. 37. Lygosoma baudinii, D. & B. — Haveri, Rigo, Aroma, Inawi, Kelesi. 38. Lygosoma rufescens, Shaw. — Aroma, Haveri, Bara Bara, Hula. 30 or 32 scales round the middle of the body, some of the vertebral scales sometimes fused, forming an interrupted series of very broad, single scales. 39. Lygosoma forbesii, Blgr. — Bara Bara. 702 G. A. BOULENGER A single specimen, differing from the type only in having 24 scales round the body instead of 26. 40. Lygosoma crassicauda, A. Dum. — Aroma, Inawi, Kelesi. 41. Lygosoma muelleri, Schleg. — Haveri. 42. Ablepharus boutonii, Desj. — Hula, Aroma, Bara Bara, Port Moresby. The very numerous specimens collected at Aroma are inte- resting as showing tlie great amount of variation to which lepidosis is subjected in this species. The number of scales round the body is 26 or 28, rarely 24; four or five upper labials anterior to the subocular; in two specimens, the fronto- nasal is in contact with the frontal, whilst in the others the praefrontals are more or less extensively in contact with each other. Taking the coloration also into consideration , the speci- mens may be referred in part to .4. boutonii, Desj., in part to A. poecilopleurus, Wiegm., whilst a few approach or represent .4. -peronii, Coct. One specimen, with 20 scales, and well-defined stripes answers to the definition of A. rutilm, Ptrs. The specimens from Hula fall into the definition of A. poe- cilopleurus and those from Bara Bara and Port Moresby into that of A. peronii. OPHIDIA. T?oitla,o. /i3.

I am now convinced that several distinct species have been mixed up under T. picturatus by Peters & Doria (Ann. Mus. Civ. Genova, XIII, 1878, p. 388), whose view I endorsed in the 'Catalogue of Snakes' (I, p. 21 o). The specimens from Halmaheira have been described by Boettger as T. punctiventris and T. hal- mahericus (Zool. Anz. 1895, pp. 29 and 30); those from Coram should be called T. elongatus^ Jan; those from New Guinea and North Australia with lb rows of scales T. picturatus^ Schleg., and T. mairii. Gray; and for those with 17 rows of scales I propose the name T. doriae. 50. Tropidonotus mairii, Gray. — Moroka, Haveri, Borepata (?) near Port Moresby. Frontal once and a half to once and two thirds as long as broad ; eye larger than in T. picturatus; two (exceptionally one) 704 G. A. BOULENGER prae- ami three (exceptionally two) postoculars ; temporals 1 -h i or 1-1-2 (rarely 2 -H 2) ; eight upper labials, fourth and lifth, or third, fourth, and fifth entering the eye, sixth and seventh equal, or sixth or seventh largest. Scales strongly keeled, in I J rows. Ventrals 141-170; suLcaudals yG-8l2. Olive, ?jrown, or blackish, w itii small black spots, or with cross-bars anteriorly; subcaudals, and often also the ventrals, edged with l)lack. Larger and more slender than T. picturalus. 51. Tropidonotus doriae, sp. n. — Dentition as in T. pictiiratns and T. mairii (^:2o-29 maxillary teeth). Eye rather large. Rostral twice as broad as deep, just visible from above ; internasals as long as broad or a little longer than broad , broadly truncate in front , as long as the praefrontals ; frontal once and a half to once and two thirds as long as Inroad, longer than its distance from the end of the snout , shorter than the parietals ; loreal deeper than long; two prae- and three postoculars; temporals usually 2 H- 2, sometimes 1 + 2 or 1 + 1 ; eight (exceptionally nine) upper labials, third, fourth and fifth (or fourth, fifth and sixth) entering the eye ; four or five lower labials in contact with the anterior chin-shields , which are shorter than the po- steriors. Scales in 17 rows, strongly keeled, outer rou feebly keeled. Ventrals 146-158; anal divided; subcaudals 09-79. Yel- lowish, reddish, or dark grey above, with more or less distinct black or blackish cross-bars as in 7'. mairii^ var. semicinclus, D. & B. ; upper labials yellowish, with black sutures; yellowish beneath, uniform or with some darker dots, none of the shields with dark edges. Total length 990 millim. ; tail 250. Haveri, Moroka. 18 specimens. 52. Stegonotus modestus, Schleg. — Hula, Haveri, Bara Bara, Samarai. The numerous specimens vary so much in scaling and in coloration that I now consider S. reticulatus, Blgr., as merely a variety of S. ///odest//s. 53.

The tibio-tarsal articulation reaches the tip of the snout or a little beyond. Males covered above with large tìat warts in ad- dition to small granules; an external vocal sac on each side of the throat, and a large oval gland on the inner side of the arm. Brown above, uniform or with small yellowish s])ots or vermiculations ; throat spotted or marbled with brown. The females, on which the species was founded, much resemble /?. guppyij, differing in the larger tympanum and the disposition of the vomerine teeth. Males differ very widely from those of that species, which are devoid of vocal sacs and humeral glands ; they show that R. macroscelis may be considered as a form connecting the group to which R. grimniens and 7?. guppyi belong with the section known as Ilylorana or Limnodytes. 2. Rana papua, Less. — Haveri, Moroka, Bara Bara, Rigo, Vikaiku. Some of the sj)ecimens bear on the sides of the body large cysts formed by Dipterous larvae, much like those produced by Batrachotnyia on tlie Australian frogs of the genus Psmdophryne. I have not been able to obtain information on these larvae from the entomological section of the British Museum. 3. Cornufer corrugatus, A. Dum. Hara Bara.

Two specimens, one with, the other without the conical tu- bercle on the eyelid whence this species derives its name. As the agreement in all other respects is very close and as the presence of a palpebral tubercle is an inconstant feature in 5. ce- lebmsis, F. Mull, I do not think great importance can be at- tached to that character. 0. Sphenophryne verrucosa, sp. n. (PI. VIII, fig. 2). — Tongue entire or slightly nicked behind. Head as long as broad ; snout obtusely pointed, projecting , obliquely truncate at the end , as long as the eye, with sharp canthus and vertical lores; interor- bital space a little broader than the upper eyelid ; tympanum moderately distinct, about half the diameter of the eye. Fingers moderately elongate, slender, terminating in large disks which are broader than long and about twice the width of the digit ; first finger shorter than second, terminating in a small disk ; toes free, with large disks which are a little smaller than those of the fingers; subarticular and metatarsal tubercles fiat, indistinct. The tibio-tarsal articulation reaches the eye or between the eye and the tip of the snout. Skin of upper parts uneven with flat warts and wavy ridges; a more or less distinct conical tubercle near the edge of the upper eyelid ; lower parts smooth , or belly slightly granulate.

Snout pointed, strongly projecting, covered with small warts; eye very small; interorbital space broad ; tympanum moderately distinct , a little larger than the eye. Fingers short, pointed, first shorter than second; toes slightly webbed at the base, the tips dilated into small disks; subarticular and metatarsal tubercles flat, indistinct. The tibio- tarsal articulations reaches the tip of the snout. Skin smooth. Brown above; a dark blotch below the eye; a fine light line from between the eyes to the vent and from the latter along the back of the thighs and the inner side of the legs ; hinder side of thighs dark brown; dirty white beneath, marbled with brown. From snout to vent 29 millim. A single specimen from Vikaiku. The specimen agrees in most points with the recently described Choanacantha rostrata, Méhely (^), but differs in the distinguishable tympanum and the somewhat longer hind limb. It also shows great resemblance to Xenorhina oxycephala, Schleg., with which I should feel inclined to unite it but for the fact that both Peters and Giinther, wdio examined the type specimens, do not mention the very prominent tooth-like processes on the palate. The specimen here described further agrees with Xenorhina oxycephala in the warty snout, and it is probable Giinther was mistaken in attributing the latter character to the defective con- dition of the type specimens.
