156 BULLETIN OF THE 
MM. sessilicauda. There are 30 rows of scales above and 32 below the lateral 
line on the colored side. 
The lateral line of the colored side is strongly arched in its anterior part over 
the base and anterior third of the pectoral fin. The arc of the curved portion 
of the lateral line (10 mm.) equals 23 times the height of the curve (4 mm.). 
The curve is entirely similar to that of VW. sessilicauda. The lateral line of the 
blind side is nearly straight, very slightly ascending anteriorly. There are 105 
scales in the lateral line to caudal base, 18 of these in the curved portion. 
The length of the head (24 mm.) equals 2 of the standard length and 23 
times the diameter of the eye. The distance from the snout to the front of 
the upper eye (6 mm.) is much greater than the distance to the lower eye 
(3mm.). The inter-orbital area is a mere narrow ridge, whose width (1 mm.) 
equals only 4 of the length of the eye. The length of the maxilla (8 mm.) 
equals + the length of the head, and on account of its oblique position its hind 
margin does not extend much beyond the vertical through the front margin 
of the lower eye. 
The length of the mandible (10 mm.) equals 4; of the head’s length. The 
teeth are uniserial, and well developed on both sides. The nostrils are in very 
short tubes, in the same line with the interorbital ridge, the posterior one being 
slightly less distant from the lower eye than the anterior is from the tip of the 
snout. A concavity above the snout. 
The dorsal fin begins upon the snout on the blind side in the perpendicular 
through the front of the lower eye. It contains 124 simple rays, the longest 
rays being in the posterior fourth of the fin, and half as long as the head. The 
anal fin begins between the tips of the ventrals and under the origin of the 
pectoral. The vent is not on the ventral outline, but on the blind side and 
close to the beginning of the anal fin. The anal is composed of 100 simple 
rays, the longest (14 mm.) being behind the middle of the fin and slightly 
longer than the longest of the dorsal (13 mm.). The caudal is sessile, rounded, 
the middle rays (20 mm.) about 4 of standard length of body. The pectoral 
is present only on the colored side, is inserted close to the edge of the oper- 
culum, its length (27 mm.) exceeding that of the head, and contained 4} times 
in the standard length. The ventral of the colored side is nearly on the ridge 
of the abdomen, while that on the blind side is mostly lateral and slightly 
larger than its fellow. The length of the left ventral (7 mm.) is contained 
about 33 times in length of head. 
The color on the left side is light brownish gray ; the fins are mostly dusky, 
except the right ventral, which is pale; the pectoral and the eyelids are 
black. 
D. 124; A. 100; V.6; P. 12. Scales, 30-105-32 (18 in curved portion of 
lateral line). 
A single specimen (XvI.) was taken by the “ Blake” off Barbadoes, in 288 
fathoms, and another one (XviI.) in the same locality, at a depth of 218 
fathoms.
