space, aud iu this are irregularly set the white markiugs. lu a baud exteudiug uuder the eye from 

 the tip of the under jaw to the posterior uuirgiu of operculum aud bounded below by the lower 

 border of the dentary are a series of five or six, more or less distinct, rather pale, vertical bars 

 extending at right angles to the axis of the body. The last one on jaw is scarcely more than a 

 dot. They gradually increase in size posteriorly and are well defined under the eye. Entire ventral 

 surface of head, abdomen, and caudal peduncle dull white. Upper surface of head reddish olive- 

 brown. The white under and dark upper surface of head are divided by a band passing from tip 

 of snout through eye and back to the operculum, which is entirely covered by it. Pectorals orange- 

 reddish, crossed by nearly obsolete bars of darker. Tail the same color, crossed by five distinct 

 vertical bars of darker, the outer of which is nearly obsolete. Dorsal the same shade of pale olive- 

 brownish as main part of body, with five widely-separated, nearly round blue spots, which bear on 

 their outer posterior side a bright orange spot. Anal slightly tinted with flesh color and crossed 

 by ten rather pale, slightly oblique bars. Ventrals nearly obsolete aud white. Eyes very protrud- 

 ing and dark. 



LiTMPENUS ANGUiLLARis (Pallas) Arrew-fish. 



3i948. (-257.) Norton Snuml, April 2,' 1881. 



Small minnow-like fish from Norton Sound, April 2, 1881 ; very rare. From median line down 

 colorless including the long anal fin. The pectoral fins are pale lemon-yellow and the caudal has 

 a dingy shade of orange. From median line up the color is a very pale olive, marked along the 

 median line by a series of eight to ten irregular and poorly-marked but distinct linear spaces covered 

 with niinnte dots. These spaces occupy the following linear position, while midway between them 

 aud the dorsal line on fore half of body is a similar but more obscure series of four or five areas 

 becoming very indistinct toward middle of length aud gradually disappearing when two-thirds 

 from head to tail. The median line of dotted spaces also grows less distinct until almost obso 

 lete near the tail. On each side of the dorsal line, and bordering the long dorsal fin the entire 

 length, extends a series of black dotted spaces more distinct than either of those on the sides. 

 The dorsal series begins from a small pentagonal dark figure on top of head just back of eyes 

 and on median line of head. The pentagon has a colorless space in center. Between the in- 

 distinct pentagon and the tail are nine to ten elongated irregular aud indistinct pairs of these 

 spaces; from the anterior border of each eye, a fine dark line of minute dots extends around the 

 snout, almost meeting its fellow in front. The cheeks aud opercles are finely pnnctulated with 

 dark dots. 



Fin rays: Dorsal fin extends from close to occiput to base of caudal and contains sixty-seven 

 spiny rays. The anal fin extends from anus to base of caudal and numbers two spiny rays fol- 

 lowed by from thirty to thirty-five soft rays. 



32945. (146.) Kigiktowik, November, 1878. 



Arroivfisli. — Rare. A few are caught all along the coast. Light olive above, white below. 

 A pair of dark lines pass from a point on the occiput along either side of the long dorsal fin and 

 terminate at the posterior extremity of the dorsal. Qn the top of head back of and between eyes 

 an oval heart-shaped space is inclosed by a dark line (which appears to be a continuation of the 

 dorsal pair of lines). The apex of the bead extends forward and a single dark line passes from it 

 midway between eyes; just back of nares it divides and each branch extends in a curved line out 

 aud forward a trifle, then bends on itself and extends backward in a curved line over the eye, then 

 back along the outer margin of dorsal surface and parallel to the median line, but much less distinct, 

 for a considerable part of the length; forming on the snout and exactly parallel to the last-named 

 line is another pair which are prolonged on either side of snout and upward to anterior border of 

 eye, back of which it is continued parallel to the other lines and forms a median lateral line. 

 Narrow golden iris, anterior and outer borders of dorsal spines black, forming the culminating 

 dark line.
