In continuation of the work [c/. anted, p. 5]. This volume is pub- 
lished out of order, the last recorded being vol. iv. The present is an 
exceedingly valuable and important memoir, especially in regard to the 
Chernetes and Opiliones. The order Chernetes {Pseudo- Scorpiones of 
other authors), pp. 1-78, pis. xvii.-xix., contains but one family, and 
comprises, in its 6 genera, 48 species, all of which are characterized, 18 
being described as new to science. The Scorpiones (pp. 79-115, pi. xx.) 
contain 5 species only, belonging to 2 genera ; 2 species are described as 
new, and 1 new genus is characterized. The Opiliones {Phalangiidea of 
authors), pp. 116-313, pis. xxi.-xxiv., occupy the larger portion of the 
volume. 100 species are distributed among 23 genera, of wliich last 4 
are characterized as new ; 34 also of the species being described as new. 
H. Lebert* shows from the experiments of Clarizio (1693), Cornelio 
(end of the 17th century), Serrao (1742), D’Azyr (1784), Walckenaer 
(1836), Panceri (1868), and Gasco, that the old and popular stories of the 
bite of the Tarentula. are untrustworthy, or much exaggerated in their 
account of its effects on man. The like opinion is also recorded by 
him from experiments with other Spiders reputed deadly, as Latrodectus 
13-guttatus, Rossi, Argyroneta aquatica, 01k,, Trochosa ingens, Bl., and 
Chcetopelma ccgyj)tiaca, Dol. The bite of the last Spider — known at 
Cairo as “ Abu-Schebet Was, however, fatal to pigeons in ten minutes 
or half-an-hour, and to a hare in four hours. 
The same author treats fully of collecting and preserving Spiders. 
A. G. Butler, in “ Science for All,” i. (pp. 176-181, woodcuts), details 
the formation of the snare of Epeira diadeniata, Clk., from original 
observation ; the mode in which the foundation-line of the snare was 
laid being actually witnessed. The line was emitted by the Spider, 
carried out by a current of air and adhered to the nearest object of con- 
tact. The snares of other Spiders are also noticed. (See also Becker, 
supra, pp. 6 & 26.) 
H. O. McCook, P. Ac. Philad. 1879, pp. 150-152, gives a minute 
account of the copulation of a species of Linyphia.
