This handsome animal, whioh I iiave much pleasure iti 

 n.uning after Sr. Budin in recognition of the excellent work 

 he has done, is readily distinguishable from all hitherto 

 describ'^d South-Amorican species by its conspicuous white 

 tail and the proportions of its skull and teeth. C. (ropicalis 

 tiichurn.i, Thos., from Panama, also has a white tail, but is 

 larger and is otherwise wholly different. 



In the present collection there are three specimeiM of this 

 genus — one larger with large teeth, and two smaller with 

 very small molars, — but all with white tails, and it was 

 natural to assume that the two smaller were females and the 

 larger one a male. On investigation, however, not only of 

 Sr. Budin's labels, but of tlie skins themselves, d imped and 

 plial)le, I find that all are certainly males, and are therefore 

 clearly not of the same species. Consequently I am com- 

 pelled further to describe 



2. Conepatus calurus, sp. n. 



(J. H30, 361. 



A white-tailed skunk with narrower skull and smaller 

 molars than in C. budini. 



Size slightly less than in C. budini, but still exceeding 

 that of C. proteus. Fur long and thick. Hairs of nape 

 either reversed or with an inclination to have twisted whorls. 

 General pattern of colour much more white than in budini\ 

 for instead of two comparatively narrow white stripes running 

 down the black back, the whole nape and back may he said 

 to be white, with merely a narrow l)lack lino (^ to ^ inch in 

 breadth, attaining ^ inch on the loins) along its centre, this 

 line altog»;ther failing in some parts. Posteriorly the white, 

 narrows, but is continuous with that of the tail. Tail bushy, 

 white, with a tew bhuk hairs iiitermixtd. 



kSkull about as lung as that of C. budini, but narrower in 

 proportion, the mastoid breadth, in a specimen with sagittal 

 crest and worn teeth, disj)roportionately less than in that 

 animal, ilesoptcrygoid fossa narrow. 



• In describing C. aja.r (Ann. & Map. Xat. Hist. (8) xi. p. 1.'37, 1018) 

 the diagonal measures of this t^oth were given, and one of these was 

 misprinted 9 instead of 0"9. The above measurements are sounder, if 

 less eai«y to take, and in the type of C. ajax are 8"3 and 7"0 respectively.
