NEW OR LITTLE KNOWN FISHES. 22_7 



head and body, a little higher than first, its middle rays 

 longest. Anal fin about 3^ in head and body; in the 

 male the first and second rays longest, the third, fourth 

 and fifth each a little shorter than the preceding one, the 

 last shortest. In the female the first ray is the shortest. 

 Caudal fin somewhat rounded. The pectoral rays below 

 the sixth are ventrally free from the connecting membrane 

 for a portion of their length. Ventral fins reaching to 

 vent, in some specimens to anal. 



Color usually reddish brown, varying to gray, intense 

 green or crimson, according to surroundings, the colors 

 developed in the presence of similarly colored algee ; dor- 

 sals, pectorals and caudal barred ; anal sometimes barred ; 

 front of spinous dorsal with an ocellated black spot. 



The types were collected in the tide pools at Neah Bay, 

 Puget Sound, by Mr. E. C. Starks. Very many speci- 

 mens are in the Leland Stanford Jr. University collection, 

 No. 3396. Others were earlier sent to us by Henry St. 

 Clair of Neah Bay. Still others were taken by Dr. Gil- 

 bert at Departure Bay, Vancouver Island. 



This species is closely related to Oligocottus maculosus, 

 with which it has been hitherto confounded. It is distin- 

 guished from the latter by having fewer filaments on the 

 head and body, an ocellated spot on front of first dorsal, 

 and by having the rays of the anal fin in the male all con- 

 nected by membrane ; the first ray of anal is much shorter 

 and weaker in borealis.

Hemitrepterus marmoratus Bean, Proc. U. S. Nat. Mua., 1890, 43. 

 Sitkalidak Island. 



This species differs from Hemitrifterus in the shorter 



first dorsal, which does not show the division found in 



the typical species of Hemitr -i-pterus. It is the type of 



the genus, Ulca, Jordan & Evermann. The specimen
