latter species is said to live in the vicinity of water, upon which it 

 runs freely, and beneath which it dives when alarmed. Tarentula 

 o.qirilonaris was newly described by Fox (1940) from specimens 

 taken on Attu Island. 



A tick, whose identity is not known to us, apparently is abundant 

 on Bogoslof Island at certain seasons. According to Morris (1937, 

 p. 952), 



The murres were pestered with a tick about the size and appearance of a 

 small wood tick. These became especially numerous on the second week in 

 August. As many as 100 were picked off the inner walls of the tent each 

 day for a week. Several got on members of the party but only one tick 

 drew blood. 



We recall picking lead-gray ticks from the body of a bird killed 

 somewhere at sea in the Aleutian Islands, but the specimens have 

 been mislaid.
