On the 13th of June, 1881, I met with an adult male of 

 this rare spider on a furze bush on Bloxworth Heath ; its 

 only previous record as a British species is that of a female 

 near Lyndhurst, Hants, in July 1858.

On the 14th of June, 1881, I found au adult female under 

 a thin clod of earth on Bloxworth Heath ; it had only occurred 

 once previously in this district (an adult male, in the month of 

 June, about ten years ago), crossing the path in a wood. 



Genus Neriene, B1. 



Neriene innotahilis, Cambr. 



Neriene innotahilis, Cambr. Spiders of Dorset, pp. 131 and 574. 



Adult females were found among dead leaves in woods near 

 Hoddesdon at the beginning of July 1881. I have usually 

 found the males adult at Bloxworth in May and the beginning 

 of June. The epigyne is large and very prominent. 



Neriene agrestis, Bl. (PI. I. fig. 2 h.)

While on a visit to Mr. F. M. Campbell at Hoddesdon, in 

 July 1881, I met with several examples of both sexes of this 

 spider among low plants, and under stones in the damp oozy 

 bed of a small stream, where it appears to be of frequent 

 occurrence, though confined to that one spot.
