^Synotus. Dr. Allen proposes to separate generically the two American 
Barbastelles, S. macrotis and JS. tow?isencU, from the European species. Proc. 
Acad. Nat. Sc. 1865, p. 173. Adding fresh descriptions of both species, he 
characterizes the new genus, which he names Corynorhinus. Prof. Peters says 
that this genus differs from Synotus only by having molars, instead of

Plecotus auritus. Mr. W. Sowerby has observed in an example kept in 
captivity that it caught flies by means of the interfemoral membrane, which, 
pressed against the abdomen, formed a kind of trap or bag, in which the in- 
sect was kept until withdrawn and devoured. Ann. & Mag, Nat. Hist. 1865,

M. E. Hardy has reported on a deposit of guano in a cave near Vesoul in 
France, the entire mass being estimated at 700 or 800 cubic metres. It is the 
accumulation of the excrements of innumerable bats inhabiting the cave.

Potamogale. Prof, du Bocage, in the memoir quoted above 
(p. 5), has given a most important contribution to the know- 
ledge of this animal. A shorter communication on the same 
subject appeared in the Proc. Zool. Soc. 1865, p. 403. He 
received from Angola the perfect skin of an adult female, a skull, 
and the greater part of a skeleton, and a foetus. It proves to
