Contains notices and descriptions of some Spiders detected in 
the South of France, three of which are described as new. 
Boisduval (Entomologie liorticole, pp. 0e5-9G) gives a general account of 
the structure and liahits of the animals of this class, and a more detailed 
description of the Acarina, with especial reference to the species which are 
injurious to horticulture. Of the Araneida he describes only Epeira diadcma 
and Theridion heriignum. 
ARANEIDA. 
Schiner (Verli. zool.-bot. Gcs. in Wien, xviii. pp. 916 922) 
records some observations on the spinning of Spiders. lie ob- 
served the formation by an Epeira of a sort of band of silk 
threads, which were then carried out and elongated by aerial 
currents, and gave rise to an infinite quantity of small floating 
threads. These adhered to neighbouring objects, and the Spider 
then made use of them to escape. The Spider could evidently 
select the threads which led to a desirable resting-place*. 
Schiner remarked that after a time the quantity of fine fila- 
* Schiner does not appear to have been acquaii ted with the observations 
of Terby and Ausserer on the same subject. See ^Record,’ 1867, p. 184.
