spider presents an intermediate type between eggs with gen- 
eral superficial segmentation of the Crustacea, such as Peneus, 
and the eggs with regular discoidal segmentation, such as those 
of certain fishes, that is to say, it has a blastulation intermediate 
between periblastulation and discoblastulation. It greatly ap- 
proaches the eggs of Chelifer (Metschnikoff), Tetranychus (Cla- 
paréde), and of insects (Bobretsky). Thus is plainly manifested 
from the outset the affinity of the Araneina with the groups of 
Arachnida and with the insects. The Bezoar or guliga stones 
are concretions or calculi formed in the “ stomach and intestines ” 
of the red monkey, a species of Semnopithecus abundant in the 
interior districts of Borneo. Mr. A. H. Everett says (in the Azz. 
and Mag. Nat. Hist., March) that “accounts vary very much 
ater. Everett adds that “ the widespread idea of the medicinal 
virtue of these concretions would lead us to suppose that there is 
some foundation for their reputation.” The Cervus maral, of 
Siberia, has recently been domesticated by Cossacks in the neigh- 
borhood of Kiakhta, in Western Siberia, where there are herds of 
been domesticated, lose a good many of their original qualities.

teeth was found among numerous remains of Ursus spelaus.

THE PerIopica Cicapa, alias, “ SEVENTEEN-YEAR LocusT.”— 
The Present year will be marked by a quite extended appearance 
of this interesting insect, both a seventeen and a thirteen year 
brood simultaneously appearing. The readers of the NATURALIST 
are doubtless familiar with the habits and natural history of Cicada 
Séptemdecim Linn., and those of the thirteen-year race (C. tredectm 
ley) which agree with it in every respect except in the time re- 
quired for full development. We will, therefore, simply quote here, 
with brief comments, what was said in 1868, in the writer’s First 
“Port on the Insects of Missouri, regarding the two broods that
