8o SNODGRASS 



very dry places ; those from Narboro were found at an elevation of 

 1,500 feet on the side of the central mountain of the island. 



HADUROIDES LUNATUS. 

 Found more numerous about Tagus Cove on Albemarle than any- 

 where else in the archipelago. Not abundant, however, here. Found 

 under bark of trees and beneath logs and stones, often in excessively 

 dry places. One specimen was dug up from eight inches below the 

 surface and another found at top of Tagus Cove mountain, 4,000 feet. 



CENTRURUS PRINCEFS, 

 Rather abundant under rocks on Hood Island. On Chatham found 

 only at an elevation of 1,000 feet in the interior of island. 



ATEMNUS INSULARIS. 

 Found only on Albemarle. Rather common under the bark of trees 

 in the Turtle Point mangrove swamp. A diligent search in the 

 swamp at Elizabeth Bay at the same time of year yielded only one 

 specimen. 



CHELANOPS NIGRIMANUS. 



This Pseudoscorpion apparently has a very different habitat from 

 the last. The single specimen obtained was found within the hollow 

 of a dead twig of a bush in the small, very dry valley at the head of 

 Tagus Cove, Albemarle. The cavity in the twig opened to the ex- 

 terior by a small round hole in one side. 



AMMOTRECHA SOLITARIA. 



Only one individual met with. Found under a log at Iguana Cove, 

 Albemarle. 



AMBLYOMMA PILOSUM. 



Extremely abundant on the land tortoises of the archipelago. 

 Found adhering, often in great numbers, to the loose skin of the neck 

 and about the bases of the legs and tail. Abundant also on the vege- 

 tation of Albemarle, but not found on birds. 



ARGAS TRANSVERSA. 



The single specimen taken was found on a leaf of a bush growing 

 at an altitude of 1,200 feet on the Tagus Cove mountain. 



TYROGLYPHUS sp. 

 All taken from orb-webs on the lava fields of Narboro near Man- 

 grove Point.
