Snout short, broad and deep; jaws about equal. Anterior nostril 

 with a thick tube; posterior nostril with a raised rim. Eye moderate, 

 the lower half silvery. Gill-slit wide, extending down in front of 12 

 pectoral rays. Thumb-tack prickles absent from the type, present 

 on the cotype. 



Dorsal unnotched, the rays increasing gradually in length. Cau- 

 dal rounded, connected for two-fifths its length to the dorsal; no 

 notch between dorsal and caudal. Pectoral with a shallow notch; 

 the lower lobe short, reaching half way between disk and vent. Disk 

 large, as broad as long; center of disk under gill-slit. Vent separated 

 from disk by two-thirds diameter of disk. 



Body grayish, mottled on sides with brown; dorsal and anal 

 mottled and barred with brown; caudal barred with light brown; 

 pectoral speckled; peritoneum silvery with scattered black dots. 



Specimens examined. 



CAREPROCTUS GILBERTI Burke, new species. 



Careproctus spectrum Bean, Proc. U. S. Nat. Mus., vol. 13, 1890, p. 40 (in part — 



confused with the type of Careproctus spectrum). 

 Careproctus colletti Evermann and Goldsborough, Bull. U. S. Bur. Fish., vol. 



26, p. 333; not of Gilbert. 



Type.— Cat. No. 64110, U.S.N.M. North of Kodiak Island, 

 Alaska, Albatross station 4292; depth, 102 fathoms. 



Distribution.— 0& British Columbia and southeastern Alaska, 

 Albatross stations 2848, 2862, 3480, 4292, 4293, and 4781; depth, 102 

 to 482 fathoms. 



Relationships. — Careproctus gilberti closely resembles Careproctus 

 ostentum. Specimens of Careproctus gilberti were found in the type 

 bottle of Careproctus spectrum, indicating that these species also 

 closely resemble each other. We find that Careproctus gilberti can 

 be distinguished from Careproctus ostentum by the distinctly larger 

 disk and from Careproctus spectrum by the smaller disk, wider gUl- 

 slit and the darkly colored stomach. 



Description of type. — Dorsal, 55; anal, 46; pectoral, 31; pyloric 

 caeca about 10. Depth of body 4 in the length without the caudal; 

 head, 3.6. Eye, 3.5 in the head; disk, 9. 



Body short, compressed, tapering rapidly to the caudal fin. Head 

 heavy, deep, compressed; depth of head greater than width of head; 

 interorbital broad and flat; cheeks vertical. Mouth broad; lateral 

 cleft reaching nearly to vertical from front of pupil; maxillary reach- 

 ing beyond pupil. Teeth slender, elongate, recurved; the lateral
