ICHTHYOLOGY 
evidently been taken out of the stomach of some voracious 
sort. The length of the snout, up to the anterior margin of 
the eye, contains three times and a third the one from that 
margin to the end of the operculum. 
SCOPBLUS CUVIERI. 
This sort would come in the division having the anal fin with 
more rays than the dorsal ; eye more than one-third the length 
of the head ; no spine over the orbit ; scales denticulated 
(subgenus Dasyscopelus, Gunther) ; it appears to differ from 
the two species included in this division, by the greater length 
of the pectorals, but comes very near to Dr. Bichardson's 
Myctophum Asper (Scopelus Asper Valenciennes). 
Height of body contained three times and eight-tenths in 
the total length ; head four times in the same ; eye twice in 
the length of the head. 
The highest part of the body is just behind the insertion of 
the pectorals ; the profile of the anterior part is very convex ; 
the nostrils are large and inflated ; the lower jaw is longer 
than the upper one ; the teeth are numerous and viliform ; 
the maxillaries are very long and almost reach the end of the 
prseoperculum ; they are slender, but become gradually rather 
broader behind, where they are rounded, and end rather 
obliquely ; the eye is very large ; the scales are very strongly 
ciliated on their margin ; very large ones extend over the two 
operculums ; on the lateral line they are very broad, and 
number forty or forty-one. These scales have a short ridge 
on their anterior part, but those on the anterior portion of the 
body present only a very faint trace of it. 
The dorsal is placed considerably nearer to the snout than 
to the base of the caudal ; it is formed of two short spines 
and of ten rays ; the first spine is much shorter than the 
second ; the caudal is strongly forked, and has nineteen long 
rays and several short ones on each side ; the anal has two 
short spines and seventeen rays ; the ventrals have eight rays; 
the pectorals are twice as long as the ventrals and extend 
backwards as far as these do ; they have seventeen rays.
