472 REPORT OF COMMISSIONER OF FISH AND FISHERIES 
above the gill-opening and is continued forward on top of head, the two meeting 
between eyes. A second series runs between eye and upper lip and curves around on 
middle of cheek, running upward to behind eye. One series runs along a fold bor- 
dering mandible, one along preopercular margin, and one on opercle. In L. fierasfer 
a few pores are visible on mandible, and one or two can frequently be made out on 
preopercular margins. The skin is very thin and delicate and the fin rays are very 
evident through the membrane. The general proportions and the dentition of the 
type are essentially as in L. fierasfer, but the vomerine teeth are longer and hooked 
backward. 
Head 4% in length; depth 13 in head; maxillary 2} in head. Mandible heavier 
than in ZL. fierasfer. Eye 5 in head; snout 4. Origin of dorsal vertically above axil 
of pectorals. Length of head and trunk one-third total length. Teeth in narrow 
bands in the jaws, a single series on vomer and palatines. Gill-membranes very 
narrowly joined below and free from the isthmus, as in L. fierasfer. Dorsal 70; anal 
60; peetorals much longer than in L. fierasfer. 
The general color in spirits is light brownish-yellow, made somewhat dusky by 
the pigment spots in the skin.. The body, and especially the fins, grows darker 
posteriorly. 
One specimen, 113 mm. long, from station 3162 (lat., N. 37° 54’ 10’; long., W. 123° 
30’; depth 552 fathoms). 
79. Melanostigma pammelas sp. noy. (Plate 35.) 
Well distinguished from M. gelatinoswm by the wider, blunter head, the smaller, less 
oblique mouth, the uniform black coloration, and the arrangement of the teeth in the 
jaws in two series. As in M. gelatinosum, the head and body are enveloped in a 
loose, thin skin, which is thrown into folds in alcoholic specimens, and entirely con- 
ceals the anterior portions of the dorsal and anal fins. On dissection the dorsal is 
seen to have its origin close behind the head, at a point over middle of pectoral fin, 
The anal begins immediately behind the vent. The rays of both fins are enveloped 
in a gelatinous subcutaneous tissue. 
The head is broad, with its greatest width equaling its greatest depth. The 
mouth is broad, somewhat oblique, with equal jaws, the maxillary reaching vertical 
from front of pupil. Both jaws with the teeth in two distinct series in front, in a 
single series laterally in lower jaw. The outer teeth in front are enlarged, almost 
canine-like. Eye large, 3 in head, twice the length of the short, broad snout. Gill- 
opening a small pore above the base of the pectorals, its diameter about one-half 
that of the eye. 
Head 8 in total length; depth 124. Pectoral narrow, its length 23 in head. 
Color intense black on head and abdomen, brownish-black elsewhere. 
The type of the species isa specimen 104 mm. long, from station 3202 (lat., N. 36° 
46’ 10’’; long., W. 121° 58’ 45’; depth 382 fathoms). Three other specimens are at 
hand from station 3126 (lat., N. 36° 49’ 20’; long., W. 122° 12’ 30’’; depth 456 
fathoms). In the smallest, 56 mm. long, the head and abdomen are jet-black, but 
the rest of body is only slightly dusky. 
Family OPHIDIIDZ. 
80. Otophidium taylori (Girard). 
Stations 3108, 3136, and 3163; depths 7 to 69 fathoms. The lateral line varies 
greatly in length. In none of the specimens does it reach the end of the tail. It 
frequently differs widely on two sides of the same fish, and varies in length from 
one-half to seven-eighths of the total length. 
81. Cateetyx rubrirostris Gilbert. 
Three specimens, stations 3199 and 3200; depths 233 and 269 fathoms. Head 4,% to 
4,4 in length. Distance from snout to origin of dorsal 3 to 3} in length. Distance 
of dorsal from occiput greater than from latter to tip of snout. Maxillary 2} in 
head, Eye longer than snout, 4§ in head:
