49 Dr. J. Anderson and Mr. W. E. de Winton on a 
raised above the forehead from between the eyes. Teeth 
extraordinarily heavy, really enormous! Premaxillse entire; 
mesial suture not complete in this young specimen, but 
completely ossified, enclosing two palatal foramina. First 
upper premolar very small, triangular, with sharp cusp 
inclined inwards, rather crushed between canines and second

It seems unaccountable how Dobson could have referred 
this actual specimen to the Southern European form, but 
such is the fact. 
The following species I have not seen :— 
Dysopes ventralis, Heuglin = Nyctinomus Cestoni’, Dobs. 
(partim). 
(This is probably N. médas, Sundev.) 
Dysopes bivittatus, Heugl. = N. bivittatus, Dobs. Cat. B. M. 
p- 426. 
(From Heuglin’s description this form would appear to be 
very nearly allied to WV. angolensis, as are also D). hepaticus, 
Heugl., and D. talpinus, Heug|.) 
Nyctinomus Bemmelent, Jentink, Notes Leyd. Mus. 1. 1879,

(May possibly be the same as the 8. African bat referred 
above to N. egyptiacus.)
