BATHYTROCTES ALVEATUS. 287 
small, slender, in single series on intermaxillaries, maxillaries, dentaries, and 
palatines ; one to several at each side of the vomer; palatine series of four 
or five; intermaxillary, palatine and vomerine larger. A moderate postor- 
bital angle from which a ridge extends to that at the opercular hinge. 
Opercles thin and membranous in greater part. Gills four; lamelle short, 
narrow; rakers slender, sharp pointed, less than half as long as the eye; 
openings very wide ; membranes not united, free from the isthmus; pseudo- 
branchiz small though well developed. 
Dorsal origin two lengths of the head from the end of the snout, above 
the hinder portion of the base of the ventral; base hardly reaching to a ver- 
tical from the middle of the anal. Anal origin below the eighth or the 
ninth ray of the dorsal. Vent below the fourth dorsal ray. Depth of the 
caudal pedicel about half of the depth of the body; caudal fin deeply 
notched. 
Scales, large, thin, deciduous, somewhat narrower in the lateral line. 
Black outside and on the linings of the body cavities. 
Total length of the described specimen nearly nine inches, 
A larger eye, shorter snout, shorter maxillary, broader occiput, and a 
shallower trough are prominent distinguishing features when this species is 
compared with B. alveatus.

Form bearing some resemblance to that of Warecetes erimelas Alc.; depth 
equal to half of the length of the head. Head long, pointed in front, one 
third of the length to the base of the caudal, with a deep longitudinal trough 
on the top between two strong ridges which converge in front of the eye, 
fading between the nostrils, and which slightly converge toward the nape. 
Snout elongate, one and one half times the eye in length, rounded at the 
end as seen from above, acute as seen from the side, concave on the sides 
from the eye to the nostrils. Eye of moderate size, two thirds of the length 
of the snout, one fifth as long as the head, as wide as the interorbital space. 
Mouth wide ; maxillary extending little if any farther backward than the
