There appears to be no doubt about this identification. 
Azara’s statement that “la lévre supérieure a beaucoup de 
rides verticales ” shows that his animal was a Nyctinomus, 
not a Molossus, and the “ autre petite oreille verticale en 
dessous,” in the description of the ear, indicates the species 
commonly known as N. gracilis, with its high vertical anti- 
tragus. Size, colour, and locality all agree perfectly. The 
other Paraguayan Nyctinomus, N. brasiliensis, is no doubt 
Azara’s Chauve-souris neuviéme, which ‘n’a pas la seconde 
oreille verticale de la précédente”’ (cf. Ann. & Mag. N. H. 
(6) xx. p. 215, 1897).

From the description of both teeth and interfemoral mem- 
brane, it is clear that Rengger’s Glossophaga villosa is not a 
Glossophaga, but its exact determination is not easy. It is 
perhaps a Lonchoglossa with the proportions of the upper 
incisors transposed. 
One of the present specimens has an atavistic anterior 
upper premolar present on the left side.

These beautiful specimens are by far the most richly 
marked of the group that I have ever seen. Their brown 
colour forms a good setting for the bright and well-defined 
white lines of the face and back. 
17. Pygoderma bilabiatum, Wagnu. 
2 4. Sapucay. February and March. 
This peculiar bat is still but sparsely represented in 
collections, and these are the first properly made skins that 
the British Museum has received. It has not previously 
been recorded from Paraguay.
