SjjkceronT/cteris toxophyllum^ Pet. 



This remarkable bat was described by Peters on a specimen 

 from unknown locality. It is therefore of interest to record 

 that a skin with its skull, apparently quite agreeing with 

 the original description and figure, has been received from 

 Merida, Venezuela. It was collected by Sefior S. Briceiio. 



Micronycteris hirsuta, Peters. 



Another bat described by Peters without exact locality is 

 Schizostoma Mrsutum (MB. Ak. Berl. 1869, p. 396). 



Among some specimens obtained by Mr. C. F. Underwood 

 in Costa Rica are a pair of bats, unfortunately somewhat 

 damaged, but apparently agreeing with Peters's and Dobson's 

 descriptions of the type of the above species in the Paris 

 Museum. 



Mr. Underwood's specimens were obtained at Pozo Azul, 

 at an altitude of 200 m., in Costa Rica. The male is orna- 

 mented with a tuft of long hairs situated just behind the 

 band connecting the two ears. 



Conepatus mapurito, Gm. 



A skunk from Guatemala, collected by Mr. C. F. Under- 

 wood, closely agrees with what is practically a topotype of 

 this species from Bogota, sent home by Mr. G. D. Child. 

 Both^ as also another specimen from Costa Rica, agree in 

 having two white dorsal stripes, which do not reach to the 

 tail and are divided by a black line extending forward between 

 them to the occiput. The hairs on the top of the neck are 

 directed forward and those on the crown backwards, the two 

 sets meeting in a crest running across from ear to ear. 



The identification of the real C. inapurito is of some 

 interest, as all the skunks of the genus Conepatus have been 

 lumped under this name. 



Oryzomys vestitus, Thos.* 



The typical skin of this species has been remade, and now 

 that it is properly shaped, certain reddish marks which were
