EEPORT ON THE DEEP-SEA FISHES. 133 



This species is also closely allied to Macrurus serrulatus, but lias the dorsal spine 

 diflferently serrated. Its eye is comparatively smaller, and the postorbital portion of the 

 head, as well as the snout longer. Mouth small.

The projecting part of the snout is short, with an obtuse upper edge, and with a 

 rough tubercle in the middle. The cleft of the mouth extends to below the middle of 

 the eye, which is comparatively large. The teeth of the outer series are visibly stronger 

 than the remainder. Barbel about as long as the eye. The interorbital space is flat, its 

 width rather less than the diameter of the eye, which, in a specimen 16 inches long, is a 

 little less than one-third of the length of the head, and more than that of the snout. 

 The scales are equally rough over the whole of their surface, the spinelets being subequal 

 in size, densely packed, closely adpressed to the scale, and not arranged in series. There 

 are seven scales in a transverse series between the first dorsal and the lateral line. 

 Second dorsal spine finely and closely serrated in front. The second dorsal fin 

 commences at a considerable distance from the first, the distance being equal to the 

 length of the head. The outer ventral ray produced into a filament. 



Habitat. — North-east of New Zealand, Station 169 ; depth, 700 fathoms. Three 

 specimens, 13, 15, and 16 inches long. 



One of these specimens had had the tail mutilated at an early stage of growth ; and 

 the fin-rays which surround the mutilated portion are longer than those on the ventral 

 edge of the extremity of the tail, simulating a caudal fin, as shown in fig. a.

Snout conically projecting beyond the mouth, with sharp and smooth canthus 

 rostralis ; a rough protuberance in front, aud one on each side of the canthus. Mouth 

 rather small, situated at the lower side of the snout ; infraorbital ridge sharp, prominent 

 in its whole length. The cleft of the mouth does not extend to below the centre of 

 the eye. Teeth in vHliform bands, in both jaws ; those of the outer series of the 

 upper jaw scarcely stronger than the others. Barbel short and slender. Interorbital
