1915.] Allen, American Deer of the Genus Mazama. 908 
171; occipitonasal length, 160; preorbital length, 86; zygomatic breadth, 
79; orbital breadth, 78; interorbital breadth, 38; occipital breadth, 60; 
breadth of braincase, 55.5; nasals, 56 & 15; maxillary toothrow, 53; m!1-3, 
29.5. Ratio of preorbital to condylobasal length, 53.7. 
Known at present only from original specimens, respectively from the 
two Tunkas, Yucatan, and Apazote, Campeche. 
This is the only species of the brown group known from north of Vene- 
zuela, as the specimen recorded by me from Nicaragua (this Bulletin, 
XXVIII, p. 95, April 30, 1910) proves on reéxamination to belong to a small 
species of Odocoileus, probably O. truez.
