Type. — Mus. Comp. Zool., No. 10,324. Young ad. ? , Boquete, Jan. 29, 1901. 



5,000 feet. 



Four specimens, Boquete, 4,000-5,000 feet altitude, January and February. 



Characters. — A large species belonging to the Oryzomys meridensis group. 

 Externally quite like 0. childi of the Bogota region of Colombia, except in the 

 color of the under parts, which are white and fulvous in patches, instead of 

 being white and gray in patches. The skull shows many good characters dis- 

 tinguishing it from that of 0. meridensis. It is slightly larger, with longer 

 rostrum, wider between orbits ; the palatal slits are about the same length, 

 but much wider ; audital bullae larger.
