Buenos Ajres fox (described below) and the members of the 

 genus Cerdocyon. This, as may be gathered from Mr. Apliii's 

 interesting account ot" tlie nianinials of Uruguay, occurs side 

 by side with the " Agouara/' whicli 1 identity with Bur- 

 meister's Canis entrerianus * . 



Pseudalopex culpceola, sp. n. 



Essentially like Ps. culp<eus, but very much smaller. 



Size appruxinuitely as in the Buenos Ayres fox {Canis 

 azarce, Jkirmeister, nee Wied). Colour about as in that 

 animal, the back mixed black and {)ale buffy, the nape like 

 the back, though less heavily blackened. Under surface 

 wiiitish, the throat nearly pure white, the iuterraniia scarcely 

 darkened, and the extreme tip of the ciiin black, the extent of 

 tiie black, however, in no way comparable to what occurs in 

 the black-chinned species. Head butty rufous. Ears, outer 

 sides of limbs, and the hams bright rufous, as in culpceus. 

 'i'ail with the usual black patch over the gland and broad 

 black tuft ; the rest of the tail-hairs creamy whitish, with 

 black tips. 



Skull very like that of the Buenos Ayres fox f, con- 

 spicuously smaller than in Fs. culpceus. Forehead very 

 slightly swollen ; postorbital processes strongly developed. 

 P* comparatively smaller. 



Uind foot of type 137 mm. ; ear 90. 



Skull: greatest length 143; condylo-basal length 140; 

 zygomatic breadth 77; nasals 51; interorbital breadth 2(\'l ; 

 breadth of brain-case 46 ; palatal length 75 ; 2/ on outer 

 edge 13'-4 ; m^ and m^ conibined 17. 



Hab. Soriano, Uruguay. Type from Santa Elena. 



Type. Adult female. B.M. no. 94. 1. 24. 2. Collected 

 29th October, 1892, by O, V. Aplin, Esq. 



Distinguishable trom all forms of theCulpeo by its smaller 

 size and from the Zorro of Buenos Ayres, the Canis azarm 

 auctorum, by its practically white chin, white underside', and 

 ferruginous limbs and hams. 



* Reise La Plata, ii. p. 400 (18(>1). Biirmeister later (Republ. Argent. 

 iii. p. lo4, 1h79) stated tliat this species bad been fuiinded on a male 

 " Ca7}is cinicrivoriis " and a female " Cams azarce'; but Cerdocyons appa- 

 rently do not occur iu this region, and, taking the malea-s the type, there 

 seema uo doubt that eiitrerianus should be identilied with Mr. Aplin's 

 Agouara, an animal much more Ccrdocyon-Wka than the members of the 

 genus I'sendulojjcx, The female was no doubt tho Uuenos Ayres fox 

 described below. 



t So strong id this resemblance that, in c;iae any mistake has been 

 made in the identihcation of the skull, I think it advisable to nominate 

 the .ikin as the type
