FAUNA OF THE ALEUTIAN ISLANDS AND ALASKA PENINSULA 405 



Sigmistes smithi, a small cottoid, was described by Schultz 

 (1939) from a collection made on Igitkin Island. 



Theragra chalco gramma chalcogramma, the Alaska pollack, or 

 silver hake, was not observed in the islands, although it was 

 discovered that a young specimen had been taken in a beach haul 

 made on Igitkin Island (fig. 26). Adults were taken readily at 

 Seward and Petersburg, on the mainland. 



Trichodon trichodon was taken several times among kelp. It is 

 a small sand fish with an undershot jaw studded with fine, sharp 

 teeth. Its odd appearance attracts immediate attention.

Zaprora silenus. A specimen was taken by one of the ship's 

 crew while he was fishing for Atka mackerel from a dory. The 

 ungainly body so startled the man that his first impulse was to 

 drop it back into the ocean. Another specimen, not recognized at 

 the time, was observed off Umnak Island, hovering under a large 

 orange jellyfish (Cijanca) at a depth of about 1 foot. It followed 

 the shelter of the umbrella and the hanging tentacles. When the 

 jellyfish was netted, the fish darted into the bell and was later 

 found in the center. Color : belly is white, sides and back are olive 

 gray ; from above, it appeared orange because of the reflected light 

 from the Cyanea. The jellyfish was taken about Vi m ^ e offshore 

 (Scheffer 1940).
