730 ADDITIONS TO THE FAUNA OF LORD HOWE ISLAND. By J. Douglas Ogilby. The following additions to the ichth3^ological fauna of the island are the result of an examination of two small Ijut highly interest-ing collections, the one obtained personally by James Brodie, Esq., the Visiting Magistrate, consisting of six species, and kindly lent to me for the purposes of this paper, the other of fifteen species, made for the writer by Mr. Walter King. The additions made in this communication include no less than three new genera, namely, (1) Iloivella, a most interesting berj^coid fish, the aberrant characters of which have determined the author in establishing for its reception a distinct family allied to the Holocentridcn and j^erhaps in some degree to the Monocentridce; (2) Machoirope, a gempylid, also of special interest as being apparently a near ally of Johnson's rare JVealotus; and (3) Dian-cistrus, a brotulid, closely allied to Dinematichthys, but with a much stronger dentition. The new species proposed number five, viz. -.—-Howella brodiei, Machcbrojje latisjnnis, Salarias insulce, Salarias alhoajnccdis, and Diancistrus longifilis; a full description is also given of a small Monacanthus, hitherto identified with Hollard's Monacanthus nitens, but exhibiting certain diffei^ential characters which may necessitate its elevation to specific rank, in which case the name alternans is proposed for it A young balistid is also described. The remaining additions are as follows : — Prionace glauca, Hippocampus punctulatus (also an addition to the Australasian fauna), 1 G anthidermis sp., Malacanthus Jwedtii (also new to Australasia), and Lotella callarias. The other species included in the collections are: — Gonorliyn-chus greyi, Trachypoma macracanthus, Epineplielus merra, Apogon norfolcensis, Fartna polylepis, Pseudolahrus lucidentus, Coris se^ni-cincta, Salarias quadricornis, and Scorpcena scahra.
