the California side of the river one and one-half miles below Draper's 

 house, about November 15, 1909. 



Meanwhile the hogs had become thoroughly frightened and had 

 taken to swimming the river twice daily, to forage for mesquite beans 

 on the Arizona side, where they appeared to feel safer. But in Decem- 

 ber traces of a lion were discovered on that side. After a pig and 

 a coyote had been killed by the lion, the latter was trailed and treed 

 by a dog, and shot by Draper. This was directly opposite the Draper 

 house, on December 29, 1909. Draper stated his belief that the lions 

 swam back and forth across the river at will. 



Both lions were males, the first (no. 10586) measuring before skin- 

 ning, 6 feet 6 inches in length, the second (no. 10587) 6 feet 4 inches. 

 The skull of the first is imperfect, the whole base having been shot 

 away; but that of the second is entire. The skins are flat, in fairly 

 good condition, and measure, as now tanned, no. 10586 : total length 

 2120 mm., tail 680; no. 10587: total length 2085, tail 710. 



They show the following characters. Pelage : short, fine-haired and 

 smooth ; longest hairs on middle of back 17 mm. in no. 10586, and 

 24 mm. in no. 10587 (in oregonensis from western California the pelage 

 is much heavier and coarser, 28 mm. long) ; tail slender due to shorter 

 clothing of hair (much more bushy in Pacific slope Felis). Coloration 

 pale : clay color on upper parts deepening towards hazel down middle 

 of back, and becoming whitish on mid-lower surface and on insides 

 of legs and thighs. Close examination discloses an admixture mid- 

 dorsally of black-tipped tawny hairs and fewer pure white hairs ; but 

 uniform pale hazel hairs predominate. Outer sides of legs and tops 

 of feet, pale clay color: hair of soles of feet between pads, prout 

 brown. Tip of tail dorsally (in both specimens), dark burnt umber for 

 about 50 mm. from tip ; tail otherwise dusky tawny dorsally and pale 

 clay color ventrally. Back of ears blackish, dulled because of admix- 

 ture of white hairs, especially towards tip and inner margin. Ears 

 relatively lightly clothed. Face pale, of color of back but duller; 

 black patches at bases of whiskers not conspicuous, much mixed with 

 whitish. Whiskers wholly white, except three or four dorsalmost ones 

 which are blackish, light tipped. 



While the skulls are small (see accompanying table of measure- 

 ments) as compared with oregonensis of western California, they are 

 larger than the type of "Felis aztecus browni" (Merriam, 1903, p. 

 73) as shown by the describer's measurements in the two particulars 

 given by him. Thev agree much more closely with the measurements
