in the disk. Fins small; dorsal origin midway from snout to end of 
caudal, base hardly longer than the orbit; anal origin very little back- 
ward of hind end of base of dorsal, Plate XXV., Fig. 5; caudal about 
as long as skull from snout to nape, slightly convex on hind margin; 
pectorals moderately broad, shorter than the caudal, fringed; ventrals 
short, fringed, length one fourth of the width of the disk. 
Color brownish white, muscular portions light flesh color; the entire 
body evidently brilliant in life with some variety of red.

Bravo. DD) GeeAT es Py 1367 C9: 
Though in a measure resembling Disranchus atlanticus Pet. in outlines, 
the present species has more of the characteristics of pediculates from great 
depths in its skin, armature and skeleton; the skin and the tubercles are 
smoother and the latter are farther apart, longer, and offer less resistance 
to the touch. Body and head together form a much depressed disk in 
which the depth is about equal to one third of its length, to two fifths of its 
width, to the postorbital width of the skull proper, or to two thirds of the 
distance from snout to nape. The form narrows anteriorly and, when in 
ordinary position, the disk appears more elongate than that of D. atlanticus ; 
it certainly is longer than wide. Tail narrow, round, tapering from the 
vent. Skull highest at the nape, descending forward to the concavity on 
the snout whence there is an abrupt rise; transversely almost flat on the 
crown, at the sides toward the disk the descent is somewhat rapid. Snout 
prominent, extending beyond the mouth, deeply excavated between the 
nostrils for the illicium, deeply notched above the nasal sacs, concave 
on the top, with a prominent tricuspid backward-hooking tubercle above 
the tip. Illicium protractile, trilobate ; median lobe largest and capable of 
bending forward and down as if the hinder side was that presented as a lure 
and in consequence of the structure invisible when the esca is retracted into 
the subrostral recess and not in function, This view is favored by black 
pigment on the front faces of the lobes on many specimens, and by 
the traces of brilliant colors on the hinder surfaces. Nasal sacs surrounded
