448 REPORT OF COMMISSIONER OF FISH AND FISHERIES. 
107. Bathyphasma ovigerum sp. nov. 
Occipital region greatly elevated, the upper profile of head strongly decurved 
above the orbits, a line from occiput to end of premaxillary processes forming an 
angle of 45 degrees with axis of body. In front of tips of premaxillary processes 
the snout descends almost vertically. Posteriorly the body tapers uniformly and 
slowly, the width of base of tail equaling one-half diameter of eye. Length of head 
equaling depth of body, 3% in length. Mouth large, horizontal, not overpassed by 
the snout; the lower jaw slightly shorter than the upper, not distinctly included. 
The maxillary reaches a vertical from posterior edge of orbit, its length 2} in head, 
its width 13 in head. Upper lip complete, the fold of lower lip extending half way 
from angle of mouth to symphysis. 
Bands of teeth very wide in the front of each jaw, becoming narrower laterally 
where the series are few in number and nearly parallel with the jaw. Anteriorly 
the series grow more and more oblique, until at front of jaw they are nearly trans- 
verse. The teeth are all simple and slender, without cusps, directed very obliquely 
backward, and movably implanted so as to admit of still further depression. The 
outer teeth in both jaws are very short, the inner ones growing gradually longer 
and becoming acicular; 16 series of teeth on each side of lower jaw, 22 series on 
each side of upper jaw. 
Posterior nostril in a short, wide tube. Eye large, the diameter of its exposed 
portion 24 in total interorbital width, 7 in head. Cheeks and temporal region 
swollen, the suborbital stay running in a notable depression between the two. Gill-slit 
wide, extending downward to opposite upper pectoral rays, longer than snout, 23 
in head. Mucous pores minute, on sides of snout, mandible, and preopercle, none 
visible on top of head. 
Disk large, nearly round, its center slightly in advance of gill-slit, its length 34 in 
head, the distance from its posterior margin to vent equaling four-fifths its own 
diameter. A small anal papilla. Pyloric ceca 19. 
Pectoral with 34 rays, not notched, the lower rays regularly diminishing in length 
to the fifth or sixth before the last, the next two or three abruptly lengthened and 
exserted. The longest ray of upper lobe equals length of snout and eye; the longest 
rays of lower lobe equals length of snout and half eye. The dorsal fin begins 
slightly behind upper axil of pectorals and contains 43 rays, the longest of which 
equals the distance from tip of snout to front of pupil. The origin of anal fin is half 
the diameter of the eyein front of the middle of body. Itcontains34rays. Caudal 
ray long and slender, with 12 rays, its basal two-fifths confluent with dorsal and 
anal, its length equal to that of pectoral fin. 
Skin thin, not conspicuously lax. Head, body, and fins white, inconspicuously 
mottled with light brown. A single specimen, 315 mm. in total length, from station 
3342, off Queen Charlotte Islands, depth 1,588 fathoms. . 
The type is a male with well-developed testes, and contained in its mouth when 
captured a spherical mass of eggs evidently belonging to this species. The eggs 
measure 44 mm. in diameter, and are well along in their development, the embryos 
distinctly visible through the very tough egg-membranes. The general form of head 
and body can be made out, and the long, continuous dorsal and anal fins running 
backward into the tail. It is probable that the male fish protects the eggs in this 
manner until after hatching. 
Family CYCLOPTERIDA. 
108. Bumicrotremus orbis (Giinther). 
Three young specimens, the largest 27 mm. long, were dredged south of Sannak 
Islands and in Bristol Bay (stations 3213, 3258, and 3274; depths 19 to 70 fathoms). 
Fin-rays in our specimens are as follows: Dorsal vi or viI-9 or 10; anal 8 to 10. We 
agree with Garman in considering it advisable to distinguish the north Pacific form 
from E. spinosus, until adequate series can be compared.
