CONGERMURZNA CAUDALIS. 305 
Dorsal origin above the base of the pectoral; anal origin two lengths of 
the head behind the end of the snout, below the fifty-first ray of the dorsal. 
Dorsal and anal moderately deep, continuous with the caudal, which is 
small, pointed, and about as long as the snout. The caudal pedicel is 
more tapering and slender than in Congermurana proriger and C. caudalis. 
Pectorals as long as the mouth, moderately broad, rounded on the outer 
edge. Lateral line distinct, arched in a low curve above the gill chamber, 
with a larger lower and a median series of minute pores, which number on 
the specimens examined from one hundred and forty-five to one hundred 
and forty-nine. 
Blackish ; fins lighter, dorsal and anal with a narrow border of black, 
pectoral rather darker in its upper half; linings of mouth to abdomen white 
or silvery covered with more or less of blackish. Total length twelve and 
one half inches. 
An individual of the length of six and one half inches is much lighter in 
color, the fins are more narrowly margined with black, the muscular regions 
are light reddish brown with puncticulations of darker near the bases of 
the fins; it is whitish on the lower half of the head and on the belly, the 
lighter color reaching up behind the cheek and on the gill flap to the middle 
of the side, and the lateral line forms a rather wide stripe of white which 
narrows backward. The snout is shorter, the eye larger, and the caudal 
region more slender than in large specimens.

Comparatively elongate, slender, and compressed ; caudal region retain- 
ing a considerable amount of its thickness and depth toward the end of the 
column; tapering forward from the shoulders to a sharp point at the end of

rather slender and sharp on the snout, tapering from the nape, somewhat 
flattened or depressed on the crown along the median keel of the skull.
