Article XV. FURTHER NOTES ON COSTA RICA 

 MAMMALS, WITH DESCRIPTION OF A NEW 

 SPECIES OF ORYZOMYS. 



By J. A. ALLEN. 



In a former volume of this Bulletin (Vol. Ill, pp. 203-218, 

 April, 1891) will be found a paper entitled 'Notes on a Collection 

 of Mammals from Costa Rica,' based on collections received from 

 the Museo Nacional de Costa Rica, through the kindness of Don 

 Anastasio Alfaro, Director of the Museum, and Mr. George K. 

 Cherrie, the Acting-Curator of Mammals, Birds and Reptiles. 

 Another small collection has been since received from the same 

 source, which adds eight species to the 38 given in the previous 

 list, and contains additional specimens of other species of special 

 interest. The present collection numbers about 50 skins, 

 each with the skull separate, representing 17 species. I also take 

 this occasion to record an additional species of Costa Rican Bat 

 recently presented to the Museum by Mr. Jose C. Zeledon, making 

 in all 9 species additional to those of the previous list. These 

 are distinguished by an asterisk prefixed to the current number.
