304 NATURAL HISTORY COLLECTIONS IN ALASKA. 



space, and in this are irregularly set the white markings. In a baud extending under the eye from 

 -the tip of the under jaw to the posterior margin of operculum and bounded below by the lower 

 border of the deutary 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 peduucle dull white. Upper surface of head reddish olive- 

 browu. 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 uearly obsolete and white. Eyes very protrud- 

 ing aud dark. 



LiTMPENUS ANGUiLLARis (Pallas) Arrow-fish. 



32948. (-257.) Nortou Soiiud, April 2, 1881. 



Small minnow-like fish froui Nortou Sound, April 2, ISSl; very rare. From median line down 

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

 a Siugy 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 aud poorly-marked but distinct linear spaces covered 

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

 and 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 and 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 ej'es 

 aud 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 and indistinct iiairs 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 punctulated 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. 



3294.5. (146.) Kigiktowik, November, 1878. 



Arrow Jisli. — 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 cither side of the long dorsal fin and 

 terminate at the posterior extremity of the dorsal. On 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 head 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 

 and 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 leugth; forming on the snout and exactly parallel to the last-named 

 line is another pair which are i)rolonged on either side of snout and ui^ward 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 aud outer borders of dorsal spines black, forming the culminating 

 dark line.
