Show 500 DR. J. E. GRAY ON THE CANIDAE. [Julie 25, line; nasals produced behind the hinder upper edge of the maxillaries. Canis (familiaris, var.) sumatrensis, Hardwicke, Linn. Trans, xiii. 235, t. 25 ; Raffles, Linn. Trans, xiii. 249. Canis sumatrensis, F. Cuv. Diet. d'H. N. viii. 557. Cuon sumatrensis, Gerrard, Cat. of Bones of M a m m . B. M . 81. Hab. Sumatra (B. 31.) ; Malacca (Carlton, B. M.) ; Java (Les-chenault, B. M . ). The skull figured by De Blainville (Osteogr. t. 8) is that of a domestic Dog, perhaps from Java. The skull in the British Museum is very like that of the Cuon alpinus. A skeleton sent from Paris, and marked " Canis javanicus" (160e), is a Cuon; and the skull is so like that of Cuon sumatrensis that I cannot discover any difference between them. I suppose this is the animal named Canis rutilans by Boie, and C. hodophylax, C. hodophilax, and C. hip-pophylax by Temminck, in the * Fauna Japonica' called Jamainu, said to have small, erect ears, and to be of the form and size of a Wolf. 4. C U O N DUKHUNENSIS. Dhole. B.M. Skull-nose slender, elongate; nasal bones the same length. Forehead much raised above the nose-line. Canis dukhunensis or Kolsum, Sykes, P. Z. S.

Wild Dog or Dhole, Williamson, Wild Sports. Whole, Wooler. Hab. India; Deccan (Sykes, B. M . ). The skull, in the British Museum, from Col. Sykes is of a young specimen changing its milk-teeth. There is a second skull in the Museum (158 6), received from the Zoological Society under the name of Canis dukhunensis; but it appears to be rather the skull of C. primcevus. Length from nose to occipital condyle of nose from front of orbits.. of lower jaw Width of brain case, over ears • of forehead between orbits .. of nose at preorbital foramen at back of zygomatic arches ..
