nate patches of teeth on the entopterygoids. Branchiostegal mem- 

 brane with nine rays. 



This new genus is alUed to both Aulopus and Seopelus. 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. 



Neoscopelus macrolepidotus, sp. n. 



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

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



Oblong, compressed, the height contained 4^ 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 the 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. 

 Between the eyes are two broad, shallow, longitudinal grooves, with 

 two low ridges between them. This part has an adipose or gelati- 

 nous appearance, and it is marked with some twenty or more trans- 

 verse beaded lines, and in the neighbourhood of the eyes with nume- 

 rous gelatinous papillae. The round eye, the iris of which has a 

 golden-greenish colour, is contained about five times in the head, 

 and is placed at a distance of not quite a diameter and a half from 

 the tip of the muzzle. It is surrounded by an adipose border, which 

 intrudes upon it at the antero -superior side, and which has a small 

 notch at the posterior side. The distance from eye to eye is nearly 

 equal to a diameter and a half. The nostrils are close together, and 

 placed halfway between the eye and the jaw ; the hinder one of 

 each pair is large. The muzzle is rounded, and short but not ab- 

 rupt. There is a protuberance on the premaxillary, behind the sym- 

 physis of the jaw. The under jaw projects slightly beyond the up- 

 per. The upper border of the mouth is formed entirely of the pre- 

 maxillary, behiud which is the toothless maxillary, having a length 

 one-half that of the head. The latter is dilated below, is furnished 

 with a very small and narrow supplementary piece, and extends back 

 to the vertical from the posterior border of the eye. There is a sco- 

 binate band of teeth on each jaw, the inner rows being rather larger 

 and almost cardiform. A portion of these dental bands is seen out- 

 side the mouth when it is closed. A narrow band of similar teeth
