As a result of the very careful mvestigatíons effected by Pe- 
trunkevich, we have laid aside Lankesters concept as regards the 
Arachnidae, and only consider as belonging to this class the land chelP 
cerids (which correspond to Lankesters and Shiplys Embolobranchiata).* 
We partly accept Pococks division, modified by Bõrner with some ah 
terations which appear to us more in accordance with acíual hnowledgej 
and present the following scheme. (*) 
For order Pedipalpi we accept the general division into UroP, 
pygi and Amblipygi, the former subdivided into 2 tribes, — Schizopel- 
tidia Bõrn and Urotrichi Poc. — each containing a single family. With; 
Gravely we consider to the Schizomidae a single genus Schizomus 
Cook) and for Trithyreus cavernicola Hansen 1926 (nec Schizomus cavem 
nicola Gravely, 1912) propose Schizomus hanseni n. n. 
( íi ) See the scheme in the oíher page.
