with a thick midrib; ears rather large, rounded; tragus oblong, 
toothed on the outer side. 
Inhab. Brazils. 
I received this specimen under the name of Phyllostoma brevicau- 
datum, but it cannot be of that species, as it has no appearance of 
any tail. It agrees with P. Neuwied’s figure in having a rather wider 
interfemoral membrane than the other Arctibei, but it differs from it 
in the membranes being much more hairy, and in the absence of the 
peculiar white, epaulet-like spots. 
Length of tarsus 72'"; foot 5'’; wing-bone 1/5"; thumb 6!", 
NyYcTIPLANUS, 0. g. 
Tail none; interfemoral membrane noe; head short ; nose-leaf 
lanceolate, erect; lower lip entire, with a triangular group of warts 
in front; cutting teeth 4; ears lateral, separate; tragus denticu- 
lated; wings broad; index finger one-jointed, middle finger four- 
jointed; thumb elongate, lower joint short, inclosed, upper joint elon- 
gated, slender, free; feet moderate, toes equal, compressed. 
This genus has the same kind of nose-leaf as Phy/lostoma, but dif- 
fers from all the genera with that form of nose-leaf in having no 
interfemoral membrane. In this character it agrees with Diphylla 
and Stenodema; but these genera only have a scarcely elevated nose- 
leaf. 
NycTIPLANUS ROTUNDATUS, N. sp. 
Dark brown, beneath paler; hair yellowish brown, with dark tips ; 
of the under side paler, with pale tips; of the sides of the body dark 
blackish brown; the fore-arm above and below, and the upper part 
of the wing-membranes near the body and on the side of the legs 
hairy; nose-leaf ovate, lanceolate, about as long as broad; apex 
acuminated; ears rather acute, naked; tragal lanceolate, acute. 
Inhab. Brazils. 
Length of wing-bone 1! 72!"; tarsus 81!"; foot 5". thumb 5!!/, 
I received this specimen under the name of Phyllostoma rotunda- 
tum, which is probably the MS. name of some German zoologist.
