2. Macrotus boconrtiaims. 



Macrotus bocourtianus, Duhson, Ann. Sc Maq. Nat. Hist, xviii. p. 436 

 (1876). 



Ears as long as the head; front margin of the nose-leaf scarcely 

 defined, continuous with the upper lip; terminal leaf narrow and 

 subacutely pointed ; last caudal vertebra and half the antepenulti- 

 mate vertebra free ; the free portion of the tail nearly equsi to the 

 thumb in length. 



Teeth as in M. waterhousii. Fur dark brown above, paler 

 beneath.

Hob. Guatemala (Vera Paz). 



The above description was taken, from the largest of four speci- 

 mens preserved in the Paris Museum, obtained by M. Bocourt in 

 Vera Paz, Guatemala, which, through the kindness of M. Alph. 

 Milne-Edwards, I was enabled to examine and describe. All the 

 specimens agree in the remarkable length of the projecting portion 

 of the tail, and in other characters described above. 



Both M. calif orniciis, Baird, and M. nvexicanus, Saussure (evi- 

 dently synonyms of M. ivaterhousii), are described as having the last 

 caudal vertebra alone free ; and in Mr. Allen's description* of M. 

 caUfornicus the length of the free portion of the taU is given as 0"*2. 

 I have examined many specimens of M. ivaterhousii of different ages ; 

 and in aU I have found the last caudal vertebra alone free. 



Although the specimens in the Paris Museum are not full-grown, 

 as the extremities of the finger-bones show, yet the metacarpal and 

 phalangeal bones are as long as those of perfectly adult specimens of 

 M. waterhousii. It follows, therefore, that this species is larger 

 than M. waterJwnsii.
