SNODGRASS 



of about 1,500 feet. Almost the entire surface of this island 

 consists of barren lava of apparently recent date. A few small 

 scattered remnants of an older and rather luxuriant vegetation, how- 

 ever, have been left uncovered, and it was on such an oasis that the 

 specimen of this species was taken. It was the only Epeirid found 

 here. The single James Island specimen was taken at James 

 Bay. 



This species is the most common Arachnid of Cocos Island, where 

 it generally constructs a fine, light and very delicate orb, but often 

 simply an irregular network of straight threads. 



TETRAGNATHA GALAPAGOENSIS. 



Taken only on Narboro Island at Mangrove Point and on Albe- 

 marle Island west of Elizabeth Bay. The webs are generally hori- 

 zontal. The Narboro specimens were taken in mangrove swamps. 

 Some of the Albemarle specimens are from reedy swamps back of 

 the mangrove swamps along the shore, and others were taken on the 

 barren lava, where they were associated with Cyclosa caudata. 



TMARUS STOLZMANNI. 



Both specimens taken in the small brushy canyon at head of Tagus 

 Cove, Albemarle. When disturbed they attempt to escape notice by 

 remaining perfectly motionless on a twig, with the long anterior legs 

 stretched out straight in front of the body. 



MISUMENA INCLUSA. 



Specimens all taken under bark of trees. The Albemarle speci- 

 mens are from the Elizabeth Bay mangrove swamps. None could be 

 found in the Turtle Point swamp on Albemarle, which swamp is, 

 with regard to all other species, much richer than the Elizabeth Bay 

 swamps. 



HETEROPODA VENATORIA. 



Common on Charles and Chatham Islands under stones, beneath 

 bark of trees and in houses. Charles and Chatham are the only 

 islands that have been inhabited for any length of time. 



OLIOS GALAPAGOENSIS. 



Found only at Tagus Cove, Albemarle, on Chatham and on Nar- 

 boro. Taken at Tagus Cove from sea level to top of neighboring 

 mountain — 4,000 feet ; found on ground and in holes of large carpen- 

 ter bee (^Xylocopa) in branches of bushes.
