CHIROPTERA. 
Three specimens of the right maxilla; from the Upper 
Kocene of Caylux. The two complete specimens show the 
minute pm. 3, Purchased, 1884. 
Two specimens of the maxilla; from the Upper Kocene of 
Caylux. ‘These specimens are rather smaller than any of 
the others; but as the dentition is precisely similar, it is 
not improbable that the difference in size is merely an 
individual or sexual character. Purchased, 1884. 
The hinder portion of the cranium; from the Upper 
Kocene of Caylux. This specimen agrees precisely with 
the smaller crania figured by Filhol in the Ann. Sci. Geol. 
vol. vil. pl. x. Purchased, 1884. 
Two specimens of the right ramus of the mandible ; from the 
Upper Eocene of Caylux. One specimen shows the three 
true molars, the alveoli of three premolars, the alveolus of 
the canine, and the two incisive alveoli. The other speci- 
men shows the three true molars and the three premolars. 
The penultimate premolar is in contact with the two teeth 
on either side, and is placed in the tooth-row. In this 
respect the species differs from the &. ferrum-equinum 
section, and agrees with the 2. calophyllus section’ ; which 
is precisely contrary to the condition prevailing in the 
upper dentition. “This is one more of the many instances 
where the fossil forms do not agree with the subdivisions 
in which the recent forms are arranged. These specimens 
agree precisely with an enlarged figure of the mandible, in 
which the anterior teeth are wanting, given by Filhol 
in the Ann. Sci. Géol. vol. vil. pl. xi. fig. 4. 
Purchased, 1884. 
Eleven specimens of the mandible, more or less complete ; 
from the Upper Eocene of Caylux. Purchased, 1884. 
Genus PHYLLORHINA, Leach’.

The genus is confined at the present day to the tropical regions of 
the Old World and Australia.
