Argyropelecus caninus sp. n. 
DPV Av As. S = 63M, 15) Bs 10: 
The form and proportions are somewhat like those of A. lychnus, Plate J, 
fig. 1; the depth of the body is more than two thirds of the total length, 
and the length of the body cavity is more than half the length from the 
snout to the end of the caudal; the depth of the caudal section at the origin 
of the anal fin is more than half the depth of the body. Head much com- 
pressed, like the body in this respect, one fourth of the total length. Snout 
short, with a sharp point on the mandibular symphysis. Mouth large ; 
maxillary nearly as long as the head. Teeth acicular, hooked, unequal, in 
single series; the fifth or the sixth on the lower jaw much the largest; six 
or eight of the hindmost on the maxillary hooking forward, all the others 
hooking backward. The blade in front of the dorsal is serrated on its 
upper edge; the abdominal keel also has serrations on its edge. The posi- 
tion of the lanterns is about as in A. lychnus: there are six branchiostegal, 
six pectoral, eleven abdominal, four ventral, six anal, and four subcaudal, 
besides one in front of the eye, another behind the orbit, two behind the 
maxillary, and one on the middle of the forehead. The ridges on the nape 
have serrated edges. There is a small spine above each shoulder on the 
nape, one below each angular, and a larger one below each preopercle. The
