9. Cynonycteris grandidieri. 



Cynonycteris grandidieri, Feiers, MB. AJcad. Berl 1869, p. 394. 



Head short and broad ; nostrils and upper lip as in Cynopterus 

 marginatus ; ears longer than the muzzle, lower half of the inner 

 margin of the ear-conch thickened, upper half convex, upper fourth 

 of the outer margin flattened beneath the tip, a small acute projec- 

 tion near the termination of the outer margin below. 



Wings from the outer toe as in Cynopterus ; tail very short, 

 scarcely exceeding the interfemoral membrane. 



The last two molars in both jaws quite rudimentary, especially 

 in the lower jaw, where they can scarcely be seen without cutting 

 down upon them, the other teeth as C. amplexicaudata. 



Fur of the back rather long and dense, much longer than that 

 of the under surface ; legs clothed with a few fine hairs. Above 

 brownish yellow, paler beneath. 



The pectoral teats (in the single male specimen) are so large that 

 at first sight the specimen from which this description is taken 

 appears to be a female. I have found a similar development of the 

 mammae in a male specimen of Cynopterus marginatus from Ceylon, 

 referred to under the description of that species. It is probable 

 that where two j'oung are born at a single birth, the male relieves 

 the female of the charge of one (as the weight of two might render 

 flight difficult or impossible), and at the same time performs the 

 office of a nurse. It is well known that many species of Bats have 

 occasionally two young at a birth, but I have never found a mother 

 with more than one clinging to her body. The size of the pectoral 

 teats in many male specimens (though in none yet observed by me 

 so large as in this species and in the other case referred to above) 

 lead me to think that instances of the male performing the office of 

 nurse are probably not uncommon among Bats.

 tail 0"-35, head l"-2, eye from end of nose 0"-4, ear 0"-7, forearm 

 2"-5, thumb 0"-8 ; third finger — metacarp. l"-5, 1st ph. 1", 2nd ph.
