ARACHNIDA. 
813 
complete revision of the modern genera of spiders with a list of 
the deseribed species, and full descriptions of the appearance 
and habits of the best-known species of each genus (European 
types being selected wherever they occur), and concludes with 
a synonymic catalogue of the European species of Araneida. 
The latter is defective in some respects, especially from the fact 
that the author appears to have been quite unacquainted with 
Mr. Blackwairs later papers on Araneida in the Annals and 
Magazine of Natural History, as also with his fine Monograph 
of the British Spiders published by the Ray Society, although 
the first part of the latter appeared in 1861. The descriptions 
are illustrated with numerous woodcuts representing species of 
the more characteristic genera, and showing the arrangement 
of the eyes and other parts from which the generic characters 
are derived.
