Oue sing-le male from the upper part of the Avsen Valley, 

 Jan. 1897. Of this species the colleetion contains even some 

 juY. females from the upper as well as from the lower part 

 of the valley. They are all young- spiders, some of them 

 have a darkbrown longitudinal indistinet marking on the 

 back, others are perfectly one-coloured.

G. immanis (SiM.). 



To identify the species deseribed by Mr. Simox is many 

 times a very dilficult matt er onh' having his descriptions to 

 stud}'. So he often describes the colour more earefally, but 

 the other organs onlv with some few words, of which it 

 sometimes is perfectly impossible to draw a sure conclusion. 

 And only more exceptionally he publishes figures of systema- 

 tically important organs. 



As for the males of the species of his genus Tomopistes 

 his descriptions are ver^* insufficient. C-oncerning T. immanis 

 he says: -bulbo ovato simplici nigroi\ on T. varius: >bulbo 

 simplici. obscure fusco». When it is question of such spe- 

 cies, which are uearly related to each other and which 

 ver}'^ probably can vary in colour and in the armature of the 

 spines, it seems to me to be necessary to describe this organ
