Mimicry in a Caterpillar.—S. E. Peal, writing from Assam 
to Nature, notices a singular case of mimicry on the part of a 
caterpillar, which, when suddenly surprised, erects its head in an 
attitude that caused the writer to mistake it for a shrew, probably 
the very animal that preys upon it. The resemblance is cause 
by two lateral prolongations and a pointed tip to the head; these 
when lifted in the peculiar attitude assumed simulate ears and a 
long muzzle, while the mouth parts in profile look like the mouth 
of a vertebrate. 
The same writer states that the tiger causes the Sambur deer 
to run to it by uttering a whistle which only an expert can tell 
from that of the deer. The eye and nose lumps of a crocodile 
are so like lumps of foam that Mr. Peal confesses he has been 
deceived until he saw the supposed foam sink. He believes this 
simulation useful to the crocodile in obtaining its food. 
emale chimpanzee in the Bidel menagerie, now at Paris, has 
been seen to weep as the climax of her grief when deprived of 
a child playmate. | 
ZOOLOGY. 
A. S. Packard on the Cave Fauna of North America, with 
Remarks on the Anatomy and Origin of Blind Forms.'—The 
author briefly describes some of the larger caves, with notes on 
their hydrography, temperature, origin, and geological age, the 
food-supply of the inhabitants, the means of entering or colo- 
nizing the cavern, and lists of each cave fauna. These notes are 
followed by a systematic description of the animals and their 
geographical distribution. - A comparative list of American and 
; cave animals shows that in America there are about 
sixty-two species to about one hundred and seventy-five in
