former list 1 included VY. chiloénsis, but find on closer examination 
that the specimens there mentioned should have been referred to an 
allied, but smaller species, the Vesp. isidori, which is probably iden- 
tical with the V. albescens of M. Geoffroy. The Bat which I now 
instance is certainly identical with the V’. chiloénsis of Mr. Water- 
house, as I have in my collection numerous specimens from various 
parts of South America, and from Mexico, with which it perfectly 
agrees, and which have been carefully compared with the type spe- 
cimen of V.. chiloénsis and found to be similar. 
2, ARCTIBEUS LILIUM, Geoff. sp. 
Phyllostoma lilium, Geoff. 
Sturnira spectrum, Gray. 
Six specimens have been sent home by Mr. Fraser. It is a very 
common species, and appears throughout the greater part of South 
America, and as far north as Mexico; but I have not seen specimens 
from Jamaica or other West Indian Islands, although the larger 
species of Arctibeus, common in South America, are also common 
there. 
3. Dresmopus ruFuws, Pr. Max. 
As many as five specimens are contained in the collection, and 
this, as well as the tolerable plenty in which it appears in other col- 
lections from South America, would seem to show that it is by no 
means a rare animal. I have also seen specimens collected in 
Mexico by M. Sallé, which were in all respects similar to those from 
South America. 
4. DieHyLia ECAUDATA, Spix. 
In the ‘ Voyage dans P Amerique Méridionale’ of M. D’Orbigny, 
plate 9, two outline figures are given of the dentition of this animal, 
from which, if we may believe in their authenticity, the Diphylla 
must be closely affined to the frugivorous Phyllostomide. It is much 
more probable, however, that these figures escaped that correction 
of the plates which they had to undergo after being executed, by the 
letter-press of the work, as the species is nowhere mentioned in the 
latter. The figures in question appear to me to refer to the cranium 
of the Phyllostoma (Arctibeus) lilium. Excepting these figures, I 
have nowhere met with any original allusion to the Diphylla smce 
the account given by the original describer, and it is probable that 
no other specimens have been met with, until the appearance of the 
present one from Mr. Fraser. The improbability of any near alliance 
with the frugivorous Phyllostomide will be best explained by the 
following note appended to this specimen by Mr. Fraser :— ; 
“Rio Napo. Murcielago. This specimen was taken by the son 
of Professor Jamieson in the act of drawing blood from a man. 
Murcielago is the Spanish name for this Bat. In general form, 
in the shape of the head and face, and in the strength of the claws, 
it bears considerable resemblance to the Desmodus, and I venture to
