of ancient Aleut villages that the middens are grayish in color. 

 Sea urchins are eaten by the present-day natives. A small child 

 was seen sucking the brown contents of one at Nikolski. The 

 shell was cracked open and the orange part (gonad and liver) 

 was eaten with the fingers. Sea urchins do not seem to be par- 

 ticularly palatable to fish. For example, in 20 cod stomachs ex- 

 amined at Chuginadak Island, only 1 small urchin was found. 

 The occurrence of sea urchin remains in sea-otter, blue-fox, and 

 sea-gull droppings has been mentioned elsewhere. 



According to Clark, no other species of Strongylocentrotus oc- 

 cur in the Aleutians. A fisherman stated that he had seen the 

 large purple S. franciscanus at Sitka, Alaska, but he had not seen 

 it in the Aleutians. 



The sand dollar, or sea biscuit, Echinarachnius parma, is thinly 

 scattered along the Aleutians. Dead shells were seen or collected 

 on the beaches of seven islands. Clark says that this is the only 

 species of sand dollar in the Aleutians.
