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.
