42 Mr. 0. Thomas on new Mammals from 



from Southern Brazil, near the typical locality, Paraguay. 

 But Veraguan and Guatemalan skins, like the S. -American 

 ones, are blackish or rufous, without any of the peculiar fawny 

 tone of F. y. tolteca. 



This cat is perhaps that referred to by Baird* and Allen f as 

 F. yaguarondi. The former of these authors had for exami- 

 nation only a skull, the latter two hunter's skins, without 

 particulars, but probably from Jalisco. 



Elliot \ places in his synonymy of F. yaguarondi " F. calo- 

 mini, Baird, Mamm. N. Amer. t. 74. fig. 2 (skull) " ; but this 

 name is not on the plate, and the nearest I can find to it is 

 Baird's " Felis cacomitl, Berl. MSS.," in the synonymy of 

 F. yaguarondi^ a reference which will certainly not give a 

 status to the name, although, as already said, the skull figured 

 is probably that of this form of the jaguarondi. 



Felis mexicana, Desm., does not appear to belong to the 

 present animal, as it is too large ; but the name is in any case 

 antedated by Turton's F. mexicana^ which is one of the spotted 

 tiger-cats. 



Lynx rufus peninsularis^ subsp. n. 



Distinguished from other N.-American lynxes by its very 

 small size (see cranial measurements below). 



General colour of back pale rufous, tipped with grey, a few 

 of the median dorsal hairs black-tipped, but there is no trace 

 of longitudinal dark lines or markings, so that the colouring 

 does not agree with that of Mearns's L. rufus californicus. 

 Belly white, with black spots. Markings on face and ears 

 apparently very much as in specimens from California proper, 

 the black spot on the upper lip almost obsolete ; the whitish 

 patch on the back of the ear not extending to the anterior 

 border. 



►Skull conspicuously different from that of any of the 

 Mexican or Californian lynxes by its much smaller size, 

 lesser development of the frontal convexity, and smaller, 

 narrower brain-case. 



Dimensions of the type (an adult male, measured in 

 flesh):— 



Head and body 607 millim.; tail 154; hind foot {more 

 Americano) 160 ; ear 81. 



Skull : basal length (basion to gnathion) 91*6 ; greatest 

 breadth 76*5 ; nasals, length in middle line '2'6'b ; interorbital
