SACCOPTERYX.—DICLIDURUS. 29 
Originally described from Surinam, 8. dilineata has been received by the British 
Museum from Pard and Bogota, as well as from Guatemala, where Mr. Salvin obtained 
it both in Vera Paz and in the forests of the Pacific coast, near Santa Lucia.

Prince Wied first described this species from a female example in which the rudi- 
mentary wing-pouch was overlooked, and he consequently referred it to the genus 
Vespertilio. Its range extends northwards from Brazil through the countries mentioned 
above, the most northern habitat yet recorded being Guatemala, where it was obtained 
by Mr. Salvin.

Hab. Mexico (Boucard, Mus. Berol.); Costa Rica, Punta Arenas (Mus. Berol.'). 
The type of this species, and of Professor Peters’s genus Balantiopteryx, was received 
from Costa Rica by the Berlin Museum; and he informs me that they have since 
obtained a Mexican specimen from M. Boucard. It does not occur in Mr. Salvin’s 
Guatemalan collections; and there being no examples in the British Museum, I am 
indebted to Dr. Peters for leave to copy a figure of its wing, designed to illustrate his 
forthcoming Monograph of the Chiroptera. 
3. DICLIDURUS. 
Diclidurus, Max. zu Wied, Isis, 1819, p. 1629. 
The most important character of this genus is the position of the tail, the proximal 
part of which is contained in a fold of the interfemoral membrane, while the terminal 
vertebrae enter a pouch in the middle of the membrane. The lower side of this pouch 
is developed into two horny concave plates or capsules, the first of which is subcrescentic
