104 DEEP SEA FISHES. 
disk trifid; those of the tail in six to eight series; a row of strong ones 
from the snout to the postfrontal region; those on the ventral surface 
and the fins smaller and more uniform; and those on the orbits very small. 
Lateral line similar to that of IZ. sparsa, Plate XVIII, but with less devel- 
opment of the fringes between the spines over the papille ; channels around 
the edges of the disk deeply excavated; second papilla at each side of the 
symphysis of the lower jaws in advance of the space between the first and 
the third; thread connecting the papilla distinct as in the Brotuloids and 
others. Vent halfway from the eye to the base of the caudal. 
Dorsal origin behind the middle of the length from snout to end of 
the tail, greatest length of fin five sevenths of that of the caudal; anal 
origin about the length of its base behind the base of the dorsal; caudal 
narrow, as long as the skull, subtruncate; pectorals narrow, fringed, as 
long as the caudal; ventrals narrow, two thirds as long as the pectorals, 
fringed. 
Brownish, with traces indicating a rose color in lifé; young individuals 
blackish ; fins blackish.

Malthopsis spinosa sp. n. 
Plate XXII. 
Brsr Ge, Di i6i5) Aaa Vora C.00: 
Nearly allied to Malthopsis erinacea, Plate XIX., but less broadly 
rounded in the anterior half of the disk, with carpalia more completely 
included in the disk, with much smaller and much more numerous spines, 
and with less development of the subopercular process. Body and head 
depressed, together forming a slightly oblong disk in which the head is as 
long as wide, or seven eighths of the length of bead and body, narrower in 
the anterior half; tail elongate, narrow, rounded, tapering from the vent. 
The disk extends on the carpals to the bases of the pectoral rays; edges of 
the disk not as much swollen as in M. erinacea; subopercular angle very 
blunt, process short. Snout little longer than the lower jaw, length equal 
to width of interorbital space, or to two fifths of the length of the orbit,
