occurrence of the species Desmodus rufus ; and though 
bats are very common about the settlements of the inte- 
rior where persons are often sucked, I have never ob- 
tained the species while travelling, all forms caught about 
the houses of the Indian stations being referable to frugivo- 
rous and insectivorous species. Glossophaga soricina is a 
common bat in such localities, and, as already mentioned, 
is looked upon by the natives as responsible for the 
damage. Possibly this may be the case, though the as- 
cription seems to me to be based on the fa6l that this is 
the species usually caught about, or observed in their 
houses at night or in the day time. If the attacks on 
the domestic animals and man be caused by thespecialised 
form, Desmodus rufus, the creature must certainly take 
refuge among the trees and stumps during the day. 
When the species is taken, it will readily be known by 
its small size, reddish colour, and peculiarly developed 
teeth. The incisor teeth are reduced to two, and are 
enlarged, long and trenchant, being nearly of the same 
size as the canines, and forming special cutting imple- 
ments. 
There yet remains another species of the leaf-nosed 
bats to be described. This is entered on the list as a 
Phyllostoma> though its exact position has not yet been 
accurately determined. It is about 14-16 inches in 
spread of wings, mouse-coloured when young and almost 
a bright tawny red when adult. The tail perforates the 
upper surface of the interfemoral membrane and projects 
above, the free portion being short, The head is rather 
elongated, but thick ; the nose-leaf well developed and 
fleshy, the edges of the horse-shoe being neatly outlined. 
The upper incisor teeth are four in number, the median
