State of Vera Cruz. It also occurs on the island of Cozumel, whence Mr. 

 Gaumer sent us a single specimen. It is found too in British Honduras and 

 in some abundance in Northern Vera Paz in the heavily forested country, 

 lying at an elevation of about 1500 feet above the sea" (Salvin and God- 

 man). 



We can not foUow Mr. Ridgway in reducing this form to a race of the 

 Brazilian M. mastacalis, from which it is widely separated geographically, 

 and consider it as distinct a species as any of the other forms herein admit- 

 ted to recognition. Its ochraceous under parts are a character shared by 

 only one other species, M. villosus, and should entitle it to stand alone. 



Specimens examined. — Mexico: Orizaba, Vera Cruz, 1; Buena Vista, 

 Vera Cruz, 2; Teapa, Tabasco, 2. British Honduras: Manatee Lagoon, 

 3; Quamin's Creek, 1; Toledo District, 2; unspecified, 1. Guatemala: 

 Choctum, Vera Paz, 3; unspecified, 7. Total, 22.
