308 NATURAL HISTORY COLLECTIONS IN ALASKA. 



32966. (aeo.) Saint Michaels, April 26, 1880. 

 Dorsal surface a slightly-mottled olive greenish. First dorsal, translucent and vaguely shaded 

 with dark. Second dorsal translucent and marked with 3 to 4 very indistinct irregular series of 

 dark mottlings, forming an irregular bar from the first ray backward and downward toward base 

 of last ray. The dark markings are spaced by irregular and dull spaces of pale dull gamboge- 

 yellow. Caudal fin crossed by 2 or 3 broad, pale, and irregular bands of dark blotchings, spaced 

 by a deeper shade of yellow than on dorsal, and the yellow taking a shade of orange near ven- 

 tral border of fin, especially near the insertion of the latter in caudal peduncle. Lower surface 

 white; silvery on ventral half of caudal peduncle, and with a brassy tinge on sides of abdomen 

 next the dark color of upper surface. The mottling is most distinct along this line, which is just 

 below median line where the two colors of dorsal and ventral surface intergrade. Branchiostegal 

 rays and membrane shaded with light purplish violet. Pectorals crossed by 4 irregular anas- 

 tamosing bars of blackish with a blotch of the same on the base of fin. The outer bar broadest 

 and about two-thirds of distance from base of fin to edge, .the part of fin beyond being vaguely 

 mottled with an irregular extension of this band ; the inner band is the narrowest and one-sixth of 

 fin length from base. Th€ dark markings are sei)arated by an equally irregular series of 4 

 bands of yellow, which gradually change from pale dull gamboge near upper surface to a dark 

 orange on lower border of fin, especially on the 4 inferior rays, which are wholly orange. The 

 dark also becomes more intense near the lower part of fin. The ventrals are a fleshy orange. The 

 anal has its rays purple tinted with 3 to 6 very irregular indistinct series or bands of pale yellow- 

 ish and pale purplish extending across fin from near first ray or anterior border backward and 

 downward toward last ray. 



OOTTUS POLTACANTHOCEPHALXJS Pallas. 



32839. (11.) Unalaska. Sculpin (Eo-loo-nudukh, Bam-suk). Common about Unalaska. 

 Sides crossed by 2 wide obscure purplish brownish bands which diverge ou the back and 

 extend to the 2 dorsals. The bands meet ou the sides of the abdomen and spread under the 

 large pectoral. The base of caudal is a light purplish brown. The space between and about the 

 illy-deftned bands is lighter and thickly mottled over the remainder of the upper surface of the 

 body by a similar but lighter purplish than, the bands. The ground color is a light clay, which on 

 the shoulders, nape, and head has a reddisii orange tinge. Along the sides and extending on the 

 pectorals and the operculum and across the top of the head is a series of light spots which are a 

 rich orange-yellow on the head, and on the base and posterior portion of the pectorals. The spots 

 are round and pure milk white. The white of the abdomen is encroached on by the dark of the 

 sides, leaving white blotches and spots, and on the caudal. peduncle the spots become much smaller 

 and almost obsolete. The dorsal fins have large irregular dark brownish blotches. The tail is 

 spotted and blotched with dark at the base. Near the end it is crossed by a wide blackish vertical 

 bar. The tip is a pale orange-yellow. The anterior parts of the pectorals are thickly mottled 

 with a dirty smoky brown not relieved by any spots. The ventrals are white, crossed by 3 dark 

 bands.

Dorsal surface olive, brightened by golden-yellow reticulating lines, which become brighter 

 and more conspicuous along the sides. Between the reticulating lines are black spots, which are 

 also more distinct on the sides. Below, on ventral surface, the color is plain white, as is also the 

 lower surface of head. The white on the lower part of the sides of head and of lips is obscured 

 by crowded punctulations which give the cheeks a plumbeous shade. The maxillaries are tinged 

 slightly with yellow. Iris yellow, with orange pigment showing. The rest of head like back; ven-
