17. Myotis, sp. Two specimens, $ ad., Dec. 2, and ? ad., 

 March 10. Nearly related to M. oxyotus (Peters), but clearly 

 different. Apparently the two specimens represent two distinct 

 species, distinguished by strong color differences, and by the 

 distribution of the hair on the interfemoral membrane. 



18. Alouata nigra (E. Geofroy). One specimen, an adult 

 male, taken at an altitude of 5000 feet. 



" I took this specimen from a band of about fifty. They were 

 the first I had seen. They travel by swinging from tree to tree. 

 As the specimen fell dead, the rest of the band did not appear to 

 be frightened by the noise of the gun. Two of them dropped 

 down from the tree to the ground where the dead one lay, picked 

 him up and stood him against the tree, as though they expected 

 him to climb it. Then they seemed to realize that he was dead, 

 and, dropping him, began to chatter ; then the whole band took 

 up the cry and scampered off through the treetops. The stomach 

 was partly filled with green leaves." H. H. K.
