On EUROPEAN SPIDERS. 23 
works of WESTRING and BLACKWALL here referred to, a tabular view is 
here given of the number of species belonging in these countries to the 
different families and genera of the order of spiders, in which I have follow- 
ed WESTRINGS system, and endeavoured to aggregate to the genera and 
families adopted by him, such species as by BLACKWALL have been other- 
wise classified. In the case of certain species among these, to me unknown, 
I have however been unable with full certainty to determine the correspon- 
ding genus in WESTRING’S system. This has been especially the case with 
several of the species comprehended by BLACKWALL, in the genus JVerene. 
Most of the species in that genus belong indeed to WESTRINGS Ærigone; 
nevertheless it is probable, that some more than the few (6) species that 
I have reckoned to Linyphia WESTR., ought to be referred to this genus: 
perhaps also one or two Neriene-species belong to WESTRINGS Theridium. 
Being unable to come to any certain conclusion in this matter, I have aggre- 
gated to the genus Ærigone WESTR. all the species (about 20 in number) 
of the genus Neriene, of whose place in WESTRING'S system I felt uncertain.
