Felis yftgiiarondi ntelantho, sub.sp. ii. 



Like true yagnarondi, but larger. 



kSize, as judged by skull, markedly larger tliau in Central- 

 American or Argentine jaguarondis. Colour of the normal 

 finely grizzled blackish brown, inclining to sepia on the 

 head and to black on the posterior back. Under surface 

 grizzled brown, the belly with a number of obsolescent 

 blackish spots. Tail and feet like body, the soles black. 



Skull larger than in any of the other jaguarondis examined, 

 strongly built, heavily ridged. Bulla? low, little inflated. 

 Upper carnassial with a large protocone in the female, a 

 comj)aratively small one in the male. 



Dimensions of male and female (the first the type), from 

 skins : — 



Head and body 830, 780 mm. ; tail 540, 535 ; hind foot 

 150, 145. 



Skull: greatest length 116, 105; condylo-basal length 

 111, 101; zygomatic breadth 75, Q)^ ', nasals (median) 24'3, 

 20 ; intertemporal constriction 29, 30 ; breadth of brain- 

 case 4:7, 45*5 ; palatal length 45, 40"5; breadth of posterior 

 palatine tube 14-2, 13; length of/ 8-4, 8-2,/ 12*8, 13-1. 



IJaJ). Tozuzo, Peru. Alt. 800 m. 



Type. Adult nuilc. B.M. no. 8. G. 17. 10. Collected 

 August, 1905, by L. Egg. Two specimens, both fully 

 adult, with basilar suture closed. 



The different forms of the jaguarondi seem to be distin- 

 guishable by little but size, as their colour varies exceedingl}^, 

 specimens from the same locality, unquestionably conspecitic, 

 often differing widely in their tone of grey, blackish, or 

 rufous. The variation in the development of the protocone 

 of the carnassial is also very striking, and is well shown in 

 the two specimens of the present form, the male having it 

 reduced (as is common in jaguarondis) and the female having 

 quite a large one. 



The largest jaguaioiidi is this one from the Peruvian Andes, 

 the central one fiom Venezuela to Argentina is intermediate 

 in size, while the Guianan and Kasti-rn Brazilian form, for 

 wliici) the name of unlcolor is available, is the smallest ol all.
