22. Felis cacomitli Baird. 



Two skins with skulls, and an additional skull, Hacienda Island, 

 June 2, and Escuinapa, Feb. 28 and June 30. 



Only one of the specimens, an old male, has external measurements, 

 as follows: Total length, 963 ; head and body, 645 ; tail vertebrae, 318 ; 

 hind foot without claws, 147; ear from notch, 51. The 3 skulls, prob- 

 ably all males (of one the sex is not given), measure as follows: 

 Total length, 91 (cT), 97, 101 (c?); basal length, 97, 90, 89; 

 zygomatic breadth, 58, 64, 67; interorbital breadth, 28, 29, 3.15; 

 mastoid breadth, 37, 38.5, 39. 



One of the skins is in the deep reddish phase, the other is inter- 

 mediate between the typical red phase and the typical gray. The 

 red example is like specimens in the red phase from Brownsville, 

 Texas. 



The species is evidently rare or more specimens would have been 

 secured.
