13S TWO NEW GENBHA AND SPECIES OF AUSTRALIAN FISHES, 



Back olive green, lower half of the sides and the abdominal 

 region silvery white washed with rose-colour; these tints are 

 sharply defined, but from the lower border of the green numejfous 

 short vertical bars, as wide as the interspaces, extending down- 

 wards encroach on the sides; a narrow bright blue stripe extends 

 backwards from the snout, above and in contact with the eye, 

 along the side almost as far as the base of the caudal fin, about 

 equally dividing the darker ground colour; they meet on the 

 upper li^D, where also they connect with a similar band which 

 traverses the side of the snout, immediately below the rostral 

 ridge, and is continued backwards below the eye to the opercles; 

 a third stripe runs along the median line of the head to the 

 dorsal where it is liroadly forked, the branches being short; 

 extremity of the snout orange on the lower surface; dorsal and 

 anal fins silvery, with several broad dark vertical bands composed 

 of numerous, closely set, blackish dots, and with a narrow marginal 

 band of the same; ventral, pectoral, and caudal tins uniform 

 grayish silvery, the latter with a dark band formed like those of 

 the dorsal along the middle ray. 



A single specimen was washed ashore during the month of 

 May, on the beach at Maroubra, and was secured by Mr. White- 

 legge, by whom it was presonted to the Australian Museum; its 

 length is 52 millimeters. 



Fetroscirtes tapeinosonia, Bleeker, and /''. rldnorhynchus, Bleeker 

 (Giinther, Fische d. Sudsee, p. 195, pi. cxv. d. it e.), would 

 belong to this genus, as well as Axpi'loiit^is Ueniatus, Quoy & 

 Gaimard (Voy. Astrolabe, Poiss. p. 719, pi. xix. f. 4). 



Dermatopsis, gen.nov. 



Body elongate and compressed, especially behind; head moderate, 

 the snout short and blunt; mouth anterior and rather wide, with 

 moderate cleft. Premaxillaries slightly protractile, forming the 

 entire dentigerous j^ortion of the upper jaw; maxillary narrow in 

 front, greatly expanded behind, extending backwards well behind 

 the eye; anterior border of the expanded portion bent downwards
