AEACHNIDA 
BY 
W. S. Dallas, F.L.S., C.M.Z.S., &c. 
A. Woi'k in progress. 
Koch, L. Die Araclmiden-Familie der Drassiden. Siebentes 
Heft, pp. 305-353, Taf. 13 & 14: 1867. 8vo. 
Of tins work only the seventh part has reached the Recorder 
as published in 1867. It will be completed in two more parts. 
B. Separate Work, 
Ohlert, E. Die Araneiden oder echten Spinnen der Provinz 
Preussen. 12mo, pp. 173, with 3 plates. Leipzig: 1867. 
This is a useful little manual of the Spiders of the province of 
Prussia, containing a clear general account of the organization 
of the animals belonging to this order, and a systematic descrip- 
tion of the species inhabiting Prussia proper. The work is of 
value as containing good characters of the families, which are 
wanting in some treatises of higher pretensions. The figures on 
the two plates represent the arrangement of the eyes in the dif- 
ferent genera. The nomenclature of the species differs consi- 
derably from that adopted by Menge, and is chiefly founded upon 
Koch^s ^ Arachniden.^ 
C. Papers published in Journals. 
Ausserer, a. Beobachtungen iiber Lebensweise, Portpflanzung 
und Entwicklung der Spinnen. Zeitschr. des Eerdinan- 
deums &c. 3*® Folge, Heft xiii. pp. 181-309. 
Contains a general account of the habits and development of 
Spiders, including some original observations. 
. Die Arachniden Tirols nach ihrer horizontalen und ver- 
ticalen Verbreitung. I. Verhandl. zool.-bot. Gesellschaft 
in Wien, Band xvii. pp. 137-170, Taf. 7 &8. 
Consists chiefly of a list of the larger Tyrolese Arachnid a 
(Araneida, Phalangiidse, and Scorpionidse), with a few introduc- 
tory remarks and descriptions of some new species.
