centre of the eye ; body covered with scales placed in transverse 

 lines, and finely striated ; one dorsal situated at near the two 

 posterior thirds of the body ; it is narrow, but high, and formed 

 of one spine and eight rays ; caudal rather pointed ; anal with 

 three spines and seven rays ; the first spine is short, the second 

 longer, and the third much longer still, and almost equal to the 

 rays ; the pectorals of twelve rays extend to the end of the ventrals; 

 no adipose fin ; the highest part of the fish is at the posterior 

 part of the head, and from thence its form goes tapering to the 

 end of the tail. The body, in the spirits, appears to have been 

 of a lilac colour, covered in a great part by a pearl-coloured tinge ; 

 very minute black dots are seen on the greatest part of the body, 

 and several marmorated spots appear on some of the specimens ; 

 the fins are of a light yellow, with some black dots at their base. 

 The specimens are about one inch and a-half long.

Count Castelnau suggests Neoscopelus as a new genus for this 

 Fish. It certainly does not tit in well to the genus Scopelus. 



Genus Alepidosaurus, Lowe. 



Body elongate, rather compressed, scaleless ; head compressed 

 with the snout much produced, and with the cleft of the mouth 

 very wide ; intermaxillary very long and very slender ; maxillary 

 thin, needle-like, as long as the intermaxillary, immoveable. 

 Teeth very unecpial in size, immoveable. A series of very small 

 teeth runs along the entire length of the intermaxillary. Teeth 

 of the palatine bone compressed, triangular, pointed, the two or 

 three anterior ones being exceedingly long and strong, and the 

 posterior ones of moderate size. Teeth of the lower jaw similar 

 to those of the palatine bones, one pair in front, and two or three 

 pairs in the middle being much enlarged. No teeth on the tongue. 

 Eye large ; pectoral and ventral fins well developed. The rayed 

 dorsal fin occupies the whole length of the back from the occiput 

 to the anal fin. Adipose and anal fins of moderate size. Caudal
