tapeworms, which filled the body cavity to the extent that the 

 fish had a pot-bellied appearance. (See also Pungitius, the many- 

 spined stickleback.) 



Gymnocanthus pistilhger is a bullhead, or cottoid, of interest 

 because it was found in a sea-otter scat on Ogliuga Island. There 

 are many species of cottoids in the shoal water and tide pools of 

 the Aleutian Islands.

Kiska Island, August 19, 1938. 



Two species of Hemilepidotus are very common in the islands. 

 H. hemilepidotus, the red sculpin, is brick red to brown in color 

 (fig. 18) ; H. jordani, the Irish Lord, is a dirty, olivaceous brown 

 with irregular dark bars (fig. 19). Sculpins are bottom feeders 

 with an amazing capacity to swallow large objects. When caught 

 with hook and line, it is often necessary to dissect the fish to re- 

 cover the hook. When the boat was at anchor, sculpins were soon 

 attracted to the spot by garbage thrown overboard from the 

 galley. Among other items found in sculpin stomachs, we have 

 noted a match box, a boiled potato, a good-sized chicken leg, and 

 the entire carcass of small bird specimens discarded from the 

 skinning room. Invertebrates seem to make up most of the natural 

 diet: brittle stars, snails, clams, crabs, shrimps, amphipods, and 

 many others. 



Color notes were taken of a specimen of H. hemilepidotus from 

 Kagamil Island: red, mottled with brown, belly is white with 

 chocolate spots; color fades rapidly. A specimen from Vsevidof 

 Island : head appears as though bright-red paint had been poured
