fewer dorsal rays ; and from N. mucosus in having the pectoral more deeply 

 notched and the anterior nostrils with a tube. Kadiak Island, Alaska. 

 Known from numerous specimens, the longest 61 mm. in length. (Gilbert 

 & Snyder.) (Named for Cloudsley Rutter, now of the U.'S. Fish Commis- 

 sion who collected in Kadiak in 1896.)

2444. NEOLIPARIS CALLYODOX (Pallas). 



Head 3f ; depth 4. D. VII, 33; A. 26; pectoral 31; caudal 14 to 16; eye 

 6|; snout 2|; pectoral If; ventral disk 2J; caudal 2. Body moderately 

 elongate, compressed posteriorly; depth of head If in its length, breadth 

 1; mouth rather large, the maxillary buried under the skin, reaching 

 slightly past anterior edge of eye; teeth small, tricuspid, in about 8 

 oblique rows; snout blunt and rounded; interorbital space wide and 

 slightly convex; posterior nostril ending in a short wide tube, the 

 anterior much smaller; behind the posterior nostril, over anterior edge 

 of eye, is a mucous pore; length of gill opening twice the diameter of the 

 eye, its lower third in front of pectoral, extending down to the second or 

 third ray ; vent about midway between posterior edge of ventral disk 

 front of anal; pectorals short and broad, with the usual notch below, 

 reaching slightly past vent; ventral disk a little longer than broad, its 

 distance from tip of lower jaw equaling its diameter; origin of dorsal 

 directly over vent, a shallow notch separating its spines from its rays; 

 front of anal much nearer snout than base of caudal, directly under dorsal 

 notch ; dorsal and anal scarcely joined to caudal^ caudal long and slender, 

 rounded behind. Among our specimens are 2 types of coloration ; the first 

 is uniform light olive brown on back, white below; fins all colorless; the 

 other is light brown on back and sides, everywhere spotted with blackish 

 spots irregular in size; lower parts light; pectoral with indistinct dark 

 cross markings; dorsal and anal mottled and spotted with blackish, 

 darker posteriorly; caudal very dark, black posteriorly; lips dusky. 

 Coasts of Alaska and Bering Sea, west to Kamchatka; generally common 

 on rocky shores ; recorded from St. Paul, Kamchatka, Plover Bay, Siberia, 

 Unalaska, and Kadiak; our specimens from the 2 islands last named; the 

 description from Unalaska specimens collected by the Albatross, the 

 longest 5 inches long. This species is evidently the original Cyclopterus 

 callyodon of Pallas, as is shown by the coloration, the small mouth, and 

 the reduced size of the gill openings. It differs from Neoliparis mucosus in 

 the much smaller ventral disk, the presence of nasal papillae, as well as 

 in proportions and coloration, (^or'AAos, beauty; 6dov$, tooth, from the 

 tricuspid teeth which Pallas had never before seen in a fish.)

 Islands. 



* The following is the substance of the account given by Pallas : Dorsal 33 ; anal 24 : 

 caudal 15; branchiostegal* 6; dorsal and anal fins continued nearly to the base of the cau- 

 dal. Body oblong, compressed ; the head depressed; the snout much depressed, rounded; 

 lower jaw included. Teeth with 3 distinct lobes ; a slender bone from the eye to the pre- 

 operculum: gill openings reduced to lunate spiracles, on each side; ventral disk small
