Biological observations. — Attus floricola fastens its co- 
coons on dead branches, etc., on the edges of the lakes in the 
Grunewald, a forest near Berlin, and I have found as many 
as twenty or thirty cocoons closely packed together in a group 
at the N.W. corner of Hundekehle See. The number of eggs 
in a cocoon varies normally from about thirty-five to fifty, 
and eggs may be found in the cocoons throughout June, July, 
and the first half of August. 
A number laid in captivity on July 12th hatched (i.e. burst 
the egg-shell) on July 28th and 29th, i. e. after sixteen to 
seventeen days. At the time of hatching the embryos are still 
very imperfectly formed and very much resemble Locy’s 
fig. 10, except that the legs, which are curved inwards and 
ventrall}', are segmented. The pedipaljis are each provided 
at the base with a small conical tooth, which is broader than 
high and drawn out at its apex into a tiny brown point. 
Shortly before hatching the egg-shell becomes stretched and 
raised on the tips of the two teeth, which then split it across 
in front of the chelicera.^ 
' I also found the two teeth in Xysticus, Tegenaria, and Age- 
lona, the teeth and the part of the cuticnla on rvliich they stand being 
Idack in the two latter genera. These teeth do not ajijjear to have been 
pi-evionsly observed, and they have been recorded in Korschelt and
