I JT^HE successful exertions of several correspondents 

 ^ enable me to give a fair report on this 



subject for the past year and a-half. From 

 Dr. A. Randall Jackson, of Hexham, I have 

 received a considerable collection of spiders 

 mostly among the more minute species, 

 which we may well call the IMicro-aranese. 

 Among these are many little-known, some 

 new to science, and several others of great 

 rarity and interest, such as Leptyphantes Whyvipcri, F. O. P.-C, 

 of which only one previous record has been made ; Gongylidiujn 

 distinctian, Simon, hitherto equally little known — (of both these 

 species the females are new to science) ; also Sintula pJwlcom- 

 vioides, Cambr., Thyreosthcnius biovaliis, Cambr., and Enlelecara 

 07m'ssa, Cambr., of which last a single example only had been 

 hitherto known (from the Cambridgeshire Fens), but has now 

 been found by Dr. Jackson on the top of Scafcll, Cumberland. 

 Dr. Jackson has also met with Diplocephalus adjaccns and 

 Diploccphalus Jacksonii, at Hexham ; both these are new to science
