Thomisus. E. Simon (Ann. Soc. Ent. Fr. 4° ser. tome vi, pp. 285-286) 
remarks with regard to this genus that the characters of its species pass so 
gradually from one to the other that its division is impossible, and indicates, 
that Philodroma (Walck.) and Monastes (Lucas) are both to be suppressed. 
Of the latter, regarded as a section of Thomisus, he gives the characters, and 
de.scribes a new species (T. piochardi, vide infra). The characters of T. para- 
doxus lapidarius (Luc.) arc also giyen (pp. 28G-287).

Drassida*:. 
Koch (Die Araclin.’-Fam. dcr Drassklen) characterizes this 
family as follows : — Tarsi without accessory claws ; eyes 8, in 2 
or 3 rows (in the latter case 2, 4, 2) ; second pair of legs not 
longer than the rest. These characters exclude the Agelenida* 
and Dysderidce, those members of BlackwalFs family Ciniflonidoi 
which have been placed by authors with the Drassidcp., and tlic 
genera Sparassus and Argyroneta, the latter referred to this 
family both by Simon and Blackwall, all of which the author 
considers to have nothing to do with the present family. Thus 
restricted, KoclFs Drassidcn in elude the following genera, tabu- 
lated 1. c. p. 2 : — 
I. Maxillce with an excavation or transverse impression. 
A. Maxilloe excavated throughout their length. 
1. Latona, g. n. 
B. Maxillm with a transverse Impression. 
1, A toothed plato on the hinder margin of the mandibular groove. 
2. Pythonissa (0. Koch). 
2. No toothed plate on the mandibles. 
a. Median fissure wanting ...... 3. Micaria (Westr.). 
= Macaria (C. Koch). 
b. Median fissure present. 
• * Posterior row of eyes bent over and broader than the anterior. 
4. Diias.sus (Walck.). 
f Posterior row of eyes straight and not broader than the an- 
terior 6 . Melanophora (C. Koch). 
II. Maxillce convex, without an impression. 
A. Eyes in 3 rows (2, 4, 2) 6. Storena (Walck.).
