Known only from the type taken at Albatross station 5511, in 
Tligan Bay, Mindanao, at a depth of 410 fathoms, where the bottom 
temperature was recorded at 53° F.

or relationships. ) 
13. CORYPHAENOIDES ASPRELLUS (Smith and Radcliffe).

C. asprellus is related to C. nasutus, a common Japanese species, 
but differs chiefly in the number and character of the scales. There 
are 5 or 6 instead of 6 or 7 between the origin of the second dorsal 
and the lateral line, excluding the lateral line scale: The spinules 
on the scales are coarser and longer; the rostral tubercles are much 
weaker and smaller, the terminal one bearing only six radiating 
spinous carinae; the scales on the preopercle have strongly divergent 
spinous carinae, while those of the same region in C. nasutus bear 
spinules in quincunx order as elsewhere on the body. Several addi- 
tional differences are apparent: the dentition is stronger; the sub- 
orbital ridge is less pronounced; and the color is much darker. Cer- 
tain proportions of the head differ: the snout is larger and its pre- 
oral projection greater; the interorbital is much wider; the maxil- 
laries are much longer (3.1 in head). 
It is perhaps more closely related to C. hoskynii?Z from the Bay 
of Bengal (1,310 fathoms), differing chiefly from Alcock’s descrip- 
tion in not having “the last spinelet of the middle series greatly en- 
larged above the others.” 
The spinules of the scales are in quincunx order, and not in rows 
as originally described. 
Known only from the type, collected at Adbatross station 5682, 
southeast of Bachian Island, Dutch East Indies, at a depth of 845 
fathoms.
