slope of the Volcan de Chiriqui. An example from the bank of the 

 Bayano River, 10 miles above the mouth of the Mamoni River, was 

 shot by H. B. Johnson of the Canal Zone police, who reported find- 

 ing it crouched on the ground and in the act of stalking a deer. 

 The specimen is similar to the type in rich reddish color. A skin 

 without skull obtained by J. H. Batty at Boquete is recorded by Allen 

 (1904, p. 70), who says of it: "This specimen agrees with 

 Dr. Merriam's description of the type, from Boquete. The sides are 

 bright reddish; the median dorsal region is much darker — or dark 

 reddish chestnut — as is also the dorsal area of the tail; the tail 

 darkens apically, so that the apical half is decidedly blackish, the 

 tip being wholly black for the terminal two inches. The inguinal 

 region is pure white, a small pectoral area whitish, and the interven- 

 ing region is like the flanks but much paler. Fur between toe pads 

 black; ears almost wholly black, the usual lighter areas being 

 brownish black and the rest deep black." 



Specimens examined : Bayano River, I ; Boqueron, I 1 ; Boquete, I." 



Genus HERPAILURUS Severtzow 

 The single species referable to this genus, commonly accorded 

 subgeneric rank only, is a small, slender, long-tailed cat, with variable 

 but unspotted coloration, ranging from Paraguay northward through 

 the warmer parts of middle America to southern Texas. Generic 

 distinction seems well shown in the skull. Contrasted with Felis the 

 more differential characters are the elongation and lateral compres- 

 sion of the cranium, accompanied by the greater elevation of the 

 rostrum in combination with the relatively short canines, the height 

 of the latter being less than that of the anterior nares. Unlike normal 

 Felis the outer instead of the inner side of the upper sectorial is 

 longest owing to the suppressed or vestigial condition of the proto- 

 cone. The foramen ovale is placed well behind the level of the 

 glenoid cavity, a position unusual among cats, and apparently asso- 

 ciated with the elongation of the braincase.

 Felis panamensis Allen, Bull. Amer. Mus. Nat. Hist., Vol. 20, p. 71, 

 February 29, 1904. Type from Boqueron, Chiriqui, Panama. 



Herpailurus yagouaroundi seems to be a dichromatic species pre- 

 senting gray and red color phases of varying tone. H. y. panamensis 

 is a dark geographic race of which the only known specimens are
