 pectoral rays; dorsals and pectoral with line cross lines; ventrals and 

 anal colorless. 



The type and only specimen is 55 mm. in length; it was dredged l)y 

 the U. S. Fish Commission steamer Albatross (station 3773) off Kink- 

 wazan Island, in Matsushima Bay; it is numbered 50915, U.S.N.M.

ArfedleUun JoB.v\N, Cat. Fish. N. A., 1885, p. 110 {uncinatuti) . 



Head broad; teeth on vomer and palatines; preopercular spines 2, 

 the upper large, strongl}^ hooked upward, with no antler-like proc- 

 esses above; no slit behind last gill; gill membranes free from isth- 

 mus; skin naked, smooth; spinous dorsal short, not notched. Northern 

 seas. This genus seems to be nearest to Artedius^ from which it 

 differs chiefly in the naked skin of head and l)od3".

D. VII or VIII-12 or 13; A. 11 or 12; P. 23, 2 (22 to 24); V. I, 3; 

 caudal with 9 divided ra3^s; lateral line 24 (22 to 26); length of head 

 (measured to end of opercular flap) 2f to 2yV; depth 4^; least depth 

 of caudal peduncle If times in orbit; its length, from base of last anal 

 ray, 2f in head. Very closelj^ related to ArtedlelJus imcinatus^ difl'er- 

 ing in the entire obsolescence of the occipital protuberances or ridges 

 in the increased number of cirri on the head, the more numerous pores 

 of the lateral line, the greater number of rays in the pectoral fins, and 

 the reduction in the ra3s of the caudal. Head evenl3" rounded in all 

 directions, the orbital region not elevated, the snout not angulated; 

 mouth slightly larger in males than in females, reaching vertical from 

 middle or posterior margin of pupil, 2i to 2| in head; lower jaw 

 shorter than the upper, a portion of the premaxillary band of teeth 

 projecting be3^ond the mandible in closed mouth; teeth cardiform, in 

 rather broad bands on jaws, and in patches of var3dng size on vomer 

 and palatines; in .some specimens a few teeth occur in a single convex 

 series on front of vomer, and but 3 or 4 form a line on palatines; in 

 others, we And an irregular double series or a narrow band on each of 

 these bones; the teeth are alwa3"s strong and are probabl3' in adult 

 specimens never entirely wanting on either vomer or palatines; longi-
