MAMMALIA — CHIROPTERA.

IsTiOPHORA. — Gray defines a new genus, under the name of 
Sturnira (Ann. Nat. Hist. x. p. 257). 
Tail and interfemoral membrane wanting ; nose-leaf lanceolate, 
simple ; tragus distinct ; inner surface of the lips bearded on the sides ; 
hind feet large ; lower lip with a single larger wart surrounded by a 
series of small ones. 
The species is called 8t. spectrum ; fur brown, with darker tips to 
the hairs, beneath pale whitish ; membranes dark blackish : Brazils. 
Unfortunately, neither are the teeth described, nor is a comparison 
made with the already identified genera. Dipliylla appears to stand 
nearest it. 
Gray has two other Brazilian species of this division, viz. : — 
1. Phyllostoma elongatum. — The front of the lower lip with a large 
triangular space divided by a central groove ; ears rounded, large ; tragus 
slender and lanceolate ; nose-leaf elongate, lanceolate, tapering. 
2. Phyllophora megalotis , — The groove of the lower lip not fringed 
on the edge ; fur blackish, rather pale beneath ; nose-leaf large, ovate- 
lanceolate, longer than broad ; ears as long as the head, rounded ; fore- 
arm bone 1" 3'" ; body and head 2 inches. 
I have characterized another Brazilian species, Phyllostoma excisum^ 
in these Archives, 8 Jahrg. 1 Bd. p. 358. 
Two species are added to the Rhinolophi, viz. : — 
1. Rhinolophus fumigatus, Riipp. (Mus. Senck. iii. p. 132) ; similar 
in the border of the nose and form of the ears to the Rh. clivosus, but 
the tail shorter, the fore-arm longer, the thick long fur dark smoke-grey: 
from Schoa: 2. Rh. morio, J. E, Gray (Ann. x. p. 257), like Rh. luctus, 
but reddish-brown, which is perhaps the effect of brandy : from Malacca, 
Singapore. 
Rh. ferrum equinum has been found in Algiers (Duvernoy in the 
Mem. de Strasb. iii. p. 3) ; and besides this, the Vespertilio murinus. 
Gymnorhina.^ — Blasius has imported some interesting 
observations on the Flight and Habits of Bats, their Wan- 
derings and Geographical Distribution, in the “ Versammlung 
der Naturforscher zu Braunschweig,” (p. 62). 
The question about their migration finds a sufficient solution in facts 
connected with the Vesperugo Nilssonii. This species exists generally 
in the latitude of 54:-58° in Russia, on the plains, and next it in the upper 
Harz and the Swedish mountains ; I may also add to these the hills at 
Regensburg. In summer, on account of the clear nights, it is nowhere 
to be found in all the north of Russia, between 60-70° north latitude : 
it is first to be seen there in August, when the dark nights begin.
