Appendix to account of Cuon Primevus, the Wild Dog, or 

 Buansu. By B. H. Hodgson, Esq. 



The pungent or peculiar odour by which the Buansu, in 

 common with the. Fox, Jackal, and Wolf, is distinguished, is 

 a subject of much interest in reference to its origin and uses, 

 and I shall therefore add to this paper a short notice of the 

 results of an examination of one male Buansu, one male 

 Jackal, and one male domestic Dog, each and all of mature 

 age. Round the entire margin of the anus, then, of the 

 Buansu, was found a series of palpable distinct pores, all of 

 equal size, and equi-distantly disposed, and in number 

 amounting to ten. Of these all but the central one on either 

 side were shallow, and consisted of little more than a re- 

 duplication of the skin ; nor did they yield any secretion on 

 pressure. But the middle one on each side was found to 

 lead by a very short straight neck to a large hollow gland 

 or reservoir, which was filled with a thin, whey-like secre- 

 tion, of pungent, certainly, but not very offensive odour, 

 and nearly, though not quite identical with the charac- 

 teristic effluvia from the body of the animal, as perceived 

 by any one approaching it when alive. These central 

 pores now adverted to, were each of them big enough to 

 admit a large quill, and the straight neck by which you 

 thence passed into the sac or reservoir, had the same dia- 

 meter with the pore, but no muscular ring, and hence the 

 contents of the sac could not be ejected with force, though 

 they trickled freely out on pressure, or on simply raising the 

 lower end of the sac. The sac (each) was as big as a spar- 

 row-egg, with thin sub-membranous walls, and a delicate 

 smooth lining like silver paper ; the secreting gland, by no 

 means palpable ; and the direction of the sac downwards, 

 whereby its contents were retained, except when very full ; 

 and I perceived no other means of retention, or of rejection
