1870.] MR. G. F. ANGAS ON NEW HELICES. 265 



underside of the abdomen is of a uniform blackish brown colour with 

 an indistinct pale longitudinal line on eitber side. 



The spinners of the inferior pair are strong but short, though 

 longer than those of the superior pair. 



The female resembles the male in general colour and markings ; the 

 sides of the abdomen, however, on the hinder half are paler than those 

 of the male, and are marked with two differently sized oblique irre- 

 gular blackish markings ; the genital aperture is simple, but of a dis- 

 tinctive form. 



Eight males and one female were received from the Rev. A. E. 

 Eaton, by whom they were found on Kerguelen's Land under stones, 

 and running also at times on the ground. 



This spider (as above observed), the only one found on the island, is 

 of great interest, being unmistakably allied to Tegeuaria and Agelena, 

 though quite distinct from both.
