166 DEEP SEA FISHES. 
thin flexible. Opercular spine weak; no other spines on the head. No 
barbels. Occipital and internarial crests of the skull moderately prominent. 
Genital papilla small. Vertical fins united ; dorsal origin on the nape, for- 
ward of the upper angle of the gill opening. Anal origin distant from the 
head less than the length of the latter, below the twenty-fifth ray of the dor- 
sal. Ventrals of a single filamentary ray, two thirds as long as the head, 
close together, at the humeral symphysis, below the hind ends of the gills. 
Pectorals wide at the base, flexible in the upper half, which is two thirds as 
long as the head, rigid in the lower section, which is twice as long as the 
upper portion and in which the rays are firmly joined in the basal half but 
flexible, spreading, and connected by membrane in the distal moiety. 
Upper section of pectoral with fifteen, and lower with fourteen or fifteen 
rays. Caudal narrow, elongate, less than half as long as the head, acum- 
inate. Scales small, thin, deciduous, Distance from bases of ventrals to 
vent nearly one and one fourth times the length of the head. 
Blackish or brown; muscular portions somewhat lighter, rusty ; linings 
of mouth and body cavity black. Top and sides of head whitish; probably 
the mucous sacs, which cover these areas, are light producers. 
Seventeen inches in total length.

Shaped much like 2. p/nnatus, but differing in numbers of fin rays and in 
form of pectoral fins. Body and head compressed, depth about one seventh 
of the total length. Head less than half as wide as long, one fifth of the 
total length, high at the nape, prominent on the internarial region, convex 
across the forehead, with strong occipital crest on the skull. Snout large, 
broad, thick, bluntly rounded at the end, high at the nostrils and above the 
middle, more than twice as long as the eye. Mouth wide, somewhat oblique ; 
maxillary nearly half as long as the head, dilated posteriorly to one and one 
half times the width of the eye, lower angle acute, midlength nearly 
below the middle of the orbit. Teeth small in villiform bands on jaws,
