Neoscopelus, gen. nov. 



Oblong, compressed, covered with large caducous scales. First 

 dorsal fin placed over the abdominal ventral fins. The pectoral fins 

 long ; their inferior rays not thicker than the rest. Mouth-cleft 

 not extending bej'ond the eyes. The maxillary dilated below, and 

 furnished with a small supplementary piece. The upper border of 

 the mouth formed entirely of the premaxillary. Scobinate bands of 

 teeth in both jaws, on the palatine bones, and on the vomer ; scobi- 

 nate patches of teeth on the eutopterygoids. Branchiostegal mem- 

 brane with nine rays. 



This new genus is allied to both Aulopus and Scopelus. In its 

 moderate number of branchiostegal rays and scopeloid form of body 

 it approaches the latter genus ; the shape of the teeth and the den- 

 tiferous vomer ally it to the former. From Odontostomus it is di- 

 stinguished by the moderate size of the eye and the immobility of 

 the teeth ; from Lampanyctus by the greater height of the body 

 and by the comparatively short rictus, which, in that genus, extends 

 much beyond the eye.

1st D. 4.9. 2nd adipose. P. 18. V. 8. A. 13. C. iv. 10 + 9. 

 iii. B. M. 9. Scales of lateral line 30. 



Oblong, compressed, the height contained 4 j times, and the thick- 

 ness 10 times in the total length. Back and sides dark red, becom- 

 ing uniformly fuscous in spirit ; cheeks silvery ; throat and belly 

 black ; the scales on the belly having a pearly iridescent centre, and 

 forming about five longitudinal rows of spots ; all the fins a pinky 

 red, approaching scarlet. None of the fins, except the caudal, are 

 scaly. 



The head is contained rather less than four times in the total 

 length. It is somewhat compressed, and the cheeks are flat. On 

 the vertex, above tbe posterior margin of the eyes, are two small 

 spines. The opercular pieces, the head between the eyes, and the 

 jaws are scaleless. The upper part of the opercle is marked by a 

 low longitudinal ridge. The neck and shoulder are rather high.
