MISCELLANEOUS. 
ON THE GENUS SACCOPTERYX OF ILLIGER. 
ScureBeEr, in his work on Mammalia, described and figured a bat 
from Surinam under the name of Vespertilio lepturus, remarkable for 
having on the end of the fore-arm-bone nearest the elbow a peculiar 
sac. Illiger, from the description (for it does not appear that he ever 
saw a specimen of the species), as was his habit, formed for this bat 
a genus which he called Saccopteryr. Geoffroy, who had never seen 
the species, referred it with doubt to his genus Taphozous, which is 
peculiar to the old world; and Temminck has followed him, and 
appears to doubt the accuracy of Schreber’s description and figure. 
Among a most interesting collection of bats, birds and other animals 
lately sent to the British Museum (collected in various parts of the 
Brazils by the late Mr. Graham, who with his family was so dis- 
tressingly lost at Para, just as he was returning home with his very 
extensive collections and notes elucidating their habits), are two 
specimens which exactly agree with Schreber’s figure. The pouches 
are about half an inch long, and are convex and bag-like on the lower 
side of the fore-arm-bone, a short distance from the elbow-joint ; 
they have a slit-like opening on the upper edge of the upper side of 
the same bone about half an inch long, and the inner surface of the 
bag is plaited, and appears to secrete an unctuous fluid. From the 
side of the neck there is a rather thick band which extends to the 
middle of the bag, and there is another lesser one from the other side 
of the bag to the edge of the membrane on the front of the wing. 
I may observe that Saccopteryx is more nearly allied to Embalo- 
nura than Taphozous, and that Cuvier (Rég. Anim. i. 121) considers 
the existence of this bag in the wing as one of the characters of 
Taphozous ; for he observes, ‘‘ Un petit prolongement de la membrane
