ARACHNIDA 79 



Three egg-cocoons were secured — one on Chatham, one on Albe- 

 marle and one on Narboro. The Chatham nest (Plate in, fig. 3) is 

 ovate, the longer diameter an inch and a half, and is composed of a 

 tough, papery web-fabric. It was attached in an upright position by 

 its larger end to an Acacia branch about six feet above the ground. 

 There was no opening, but within was an adult female and a packet 

 of eggs. The Albemarle nest resembles the Chatham one, but is 

 smaller and has an opening in the top closed by a flap which the fe- 

 male within drew tightly shut when disturbed by thrusting one of her 

 legs over the outside of it. In this one were the adult female and nu- 

 merous young spiders. The Narboro nest (Plate iii, fig. 4) differs 

 from the other two. It consists of a silken cell attached to the upper 

 surface of a flat mangrove leaf, and has two curled leaves closely 

 fastened down to its top and sides, being thus flattened, and wholly 

 hidden within the leaves. It had no opening, but contained, as did 

 the Chatham nest, a packet of eggs, and an adult female who was very 

 active when liberated. The eggs, in both cases, were held in a spher- 

 ical mass by a very gauzy silk wrapping. 



ODO INSULARIS. 

 Specimens taken on the ground under logs about Tagus Cove, 

 Albemarle. 



LYCOSA GALAPAGOENSIS. 



Found rather abundant on Chatham Island about Wreck Bay and in 

 the higher cultivated parts. The Albemarle specimens were taken at 

 sea level near Iguana Cove. Not met with elsewhere in the archi- 

 pelago. 



LYCOSA ALBEMARLENSIS. 



Taken only in the long wet salt grass growing about the inner edge 

 of the Turtle Point mangrove swamp, Albemarle Island. 



LYCOSA SNODGRASSI. 

 Taken on Chatham and Albemarle at the same localities as Lycosa 

 galapagoensis. The Hood specimens were secured under rocks near 

 Gardner Bay. 



PHIL^US PACIFICUS. 



The Narboro specimen was taken from the inside of a silk cocoon, 



otherwise empty, attached to a mangrove leaf in a swamp at Mangrove 



Point. 



CHARINUS INSULARIS. 



Rather rare in the archipelago; found on the ground under logs 

 and stones. The Albemarle specimens were taken at Tagus Cove in
