Heft. 1-6, pp. 1-304, Taf. 1-12. 8vo. Nurnberg : 1866. 
Of this work, which is to be completed in eight parts, the 
Recorder has received six. It is a monograph of the Spidei‘s 
belonging to the family Drassidoij with analytical tables of the 
genera and species. The plates contain figures only of the 
epigynes and male palpi of the different species. 
B. Separate Work. 
Staveley, E. F. British Spiders : an Introduction to the Study 
of the Araneidse of Great Britain and Ireland. I2mo. 
London : Reeve, 1866, pp. xv. & 280, with 16 plates. 
This is a popular history of British Spiders, derived chiefly 
from Blackwalhs work on the same subject published by the 
Ray Society. As in that work, no attempt to characterize the 
families is made : the genera and species correspond precisely 
with those adopted by Blackwall; but in some of the larger 
genera, such as Theridion, Linypliia, Epeira, and others, the 
order of the species is changed, and the genera are broken up 
into sections, an arrangement which will facilitate the determi- 
nation of the species. Without pretending to originality, the 
little book has evidently been compiled by a person acquainted 
with the subject ; and the descriptions, with the aid of the excel- 
lent plates (which are drawn by Tuffen W est) , ought to enable 
any moderately intelligent reader to prosecute the study of our 
British Spiders. The Plates include coloured figures of one or 
more species of each genus ; and two of them are devoted to a 
series of outline figures showing the arrangement of the eyes in 
the different genera. A few woodcuts are also scattered through 
the book, especially in the introductory portion, treating of the 
general structure of Spiders.
