3. On some Crustaceans from the South Pacific. — Part I. 
Stomatopoda. By Lancelot Alexander Borradaile, 
M.A., Lecturer in Natural Sciences at Selwyn College, 
Cambridge \ 
[Eeceived November 30. 1897.] 
(Plates y. & VI.) 
The collections of Crustaceans treated of in this paper are 
those of Mr. J. S. Gardiner, of Gonville and Caius CoDege, 
Cambridge, from the islands of Funafuti (Ellice group) and 
Eotuma, and of Dr. A. Willey, from Xew Britain, the Loyalty 
Islands, and other South Pacific localities. Both of them were 
made in connection with the " Balfour Memorial Fund," Dr, Willey 
holding the Balfour Studentship and Mr. Gardiner being also 
aided by a grant from the fund.

In the followiug lists three of the species will be seen to 
be new. 
Mr. Gardiner's collection contained examples of : — 
Protosqidlla cerebralis Brooks. 1 (f from Eotuma. 
Gonodactylus chiragra (Fabr.). 8 cJ and 8 5 from Kotiima ; 
1 c? and 5 $ from Funafuti. 
Gonodactylus chiragra (Fabr.), var. smitJiii Pocock. 1 S and 
2 $ from Eotuma. 
Gonodactylus glabrous Brooks. 1 5 from Eotuma. 
Gonodactylus espinosus, sp. n. 1 c? from Eotuma. 
Odontodactylus scyllarus (Linn.). 2 cS and 2 $ from Eotuma. 
Pseudosquilla ciliata (Tabr.). 1 $ from Funafuti. 
Pseudosquilla oxyrhyncha, sp. n, 1 d from Eotuma. 
Lysiosquilla maculata (Fabr.). 1 c? and 1 5 from Eotuma. 
Dr. Willey's collection comprised specimens of : — 
Protosquilla cerehi-alis Brooks. 2 $ from Sandal Bay, Lifu, 
Loyalty Islands ; 1 c? from Pigeon Island, New Britain. 
Protosquilla trisjnnosa (Dana). 1 2 from Lifu, Loyalty 
Islands. 
Gonodactylus chiragra (Fabr.). 2 c? and 5 2 from Lifu, 
Loyalty Islands ; 1 d and 1 2 from the Isle of Piues ; 
1 cT and 1 2 from Talili Bay ; 12 from Ealu ; 1 d , 
locality not stated. 
Gonodactylus chiragra (Fabr.), var. smithil Pocock. 1 cJ and 
2 2 from Lifu, Loyalty Islands. 
Odontodactylus scyllarus (Linn.). 1 2 from New Britain. 
Squilla inuUituherculata, sp. n. Id" and 2 2 from Sandal Bay, 
Lifu, Loyalty Islands. 
Pseudosquilla ciliata (Fabr.). 1 2 from Uvea, Loyalty Islands ; 
1 6 from Blanche Bay, Loyalty Islands. 
I now proceed to general remarks on the above-mentioned 
species. 
1. Protosquilla cekebealis Brooks. (Plate V. iig. 6«.) 
Protosqidlla cerebralis, Brooks, ' Challenger ' Stomatopoda, p. 72, 
pi. xiv. figs. 2 and 3, pi. xvi. figs. 2 and 3 (1886). 
Brooks's examples of this species were all females. Fortu- 
nately, however, Mr. Gai'diner's and Dr. Willey's collections each 
contain a male specimen, so that I have been able to have a figure 
made of the pecuUar structure on the endopodite of the 1st abdo- 
minal appendage in this sex (fig. 6 a, Plate V.). The importance, 
from a systematic point of view, of a record of the form of this 
organ in each species has been pointed out by Brooks (loc. cit. 
p. 13). 
1 c? from Eotuma ; 2 2 from Sandal Bay, Lifu, Loyalty Islands ; 
1 c? from Pigeon Island, New Britain.

2. Peotosquilla teispinosa (Dana). (Plate Y. figs. 1, la.) 
Oonodactylus trisphiosus, Dana, Zool. U.S. Expl. Exped., Crust, 
i. p. 623 (1852) ; Miers, A.un. Mag. Nat. Hist. 5, v. p. 121, 
pi. iii. fig. 10(1880). 
Protosquilla trisinnosa, Brooks, ' Challenger ' Stoinatopoda, p. 71 
(1886). 
The naming of this species is generally credited to White (List 
Crust. Brit. Mus. p. 75, 1847), but, as" White published merely 
the name and a reference to a plate (in the " Zoology of the Voyage 
of the ' Erebus ' and ' Terror ' ") which never appeared, the true 
author is Dana, who was the first to describe it. 
No complete figure of /-'. irispinosa has ever been published, and 
as the representation of the telsou given by Miers does not accurately 
depict either White's original specimen in the British Museum 
or that in Dr. AVilley's collection, which themselves agree 
closely, I have determined to append a figure to the present note. 
All descriptions of this species hitherto published have over- 
looked the fact that the three tubercles of the telson are not 
smooth, but covered with miuute spinules. An amended definition 
of the species will run as follows : — 
" A Protosquilla ^^ith the two antero-lateral spines of the ros- 
trum nearly as long as the median ; carapace with corners nearly 
rectangular, anterior more acute than posterior ; fifth abdominal 
segment longitudinally corrugated ; sixth abdominal segment 
clearly marked off from the telsou, and bearing six smooth tubercles ; 
telson bearing a median and two lateral large tubercles coAered 
with minute spinules, the median anterior to the two laterals ; 
postei-ior border of telson divided by deep narrow fissures into six 
lobes ; submedian, intermediate, and lateral spines of the telson 
small and placed in notches ; several submedian spinules." Length 
about 40 mm. 1 5 specimen from Lifu, Loyalty Islands.

fig. 8.) 
Squilla chiragra, Fabricius, Ent. Syst. t. iii. pt. i. p. 513 (1793). 
Gonodactylus cliiragra, Latreille, Eucycl. Meth. x. p. 473 (1825); 
Dana, Zooh U.S. Expl. Exped., Crust, i. p. 623, pi. xli. figs. 5 a, 6 
(1852); Miers, Ann. Mag. Nat. Hist. 5, v. p. 118(1880); Brooks, 
' Challenger' Stomatopoda, p. 56, pi. xv. fig. 4 (1886). 
Gonodactylus smithii, Pocock, Ann. Mag. Nat. Hist. 6, xi. p. 475, 
pi. XX. B. fig. 1 (1893). 
Pocock has described, under the name of Gonodactylus sniithii 
(Plate Y. figs. 2, 2 a, b), a form differing from the type as follows : — 
(i.) The crests upon the sixth abdominal segment and telson 
are much more compressed and carinate than in chiragra. 
(ii.) The crests upon the sixth abdominal segment are produced, 
without constriction, into long spines.
