126.1; condylobasal length, 118.7; interorbital breadth, 26.8; least width of palatal 

 shelf, 16.8; maxillary tooth row (alveoli), 45.1; upper carnassial, crown length, 

 9.6, crown width, 9.8. 



Remarks. — The general range of the present subspecies embraces the 

 peninsula of Yucatan and adjoining territory as far south and west as 

 the Isthmus of Tehuantepec. Like the representatives of other widely 

 ranging sul)species inhal)iting the general region it is characterized by 

 pale colors. Occasional specimens, however, as one from Huilotepec 

 (near Tehuante])ec), Oaxaca, have the upper parts more heavily over- 

 laid with black, indicating gradation toward the darker Central 

 American forms. It is closely allied to P. I. hernandezii, but the 

 characters pointed out are distinctive.
