CYOK.

pm. ^, m. Iizi- 1'*^<^ muzzle is proportionally shorter, and the 

 line of the face, when viewed from the side, is slightly convex, 

 instead of being straight or concave as in other Canidce. 



The mammte are more numerous, being 12 or 14 instead of 10. 

 There is long hair between the foot-pads. 



In all other respects the genus Cifon agrees with Canls. Cyan 

 has a very peculiar geographical distribution, being found in 

 Central Asia as far north as the Altai, the Amurland, and Saga- 

 lien, and throughout the Oriental region, but not, so far as is 

 known, in Northern China or Japan. 



There is some doubt about tlie specific characters, but two 

 distinguishable forms appear to inhabit our area *. 



Synopsis of Indian and Burmese Species. 



A. Larger and stouter; hair long-, with woolly 



uuderfur, ferruginous red to tawny. Skull 

 G"75 to 7 inches long ; tarsus and hind 

 foot over 7 inches C. duhhtinensis, p. 143. 



B. Smaller and slighter ; hair short, no under- 



fur, brighter ferruginous. Skull 6'2o inches 



long, tarsus 6 C. rutilans, p. 147. 



The term "wild dog" applied to these animals is clearly a 

 misnomer, for in every important detail in which the genus Gyon 

 differs from Canis (wolves and jackals) — in the form of tlie skull, 

 the dentition, and the number of mammae — domestic dogs agree 

 with the latter and not with the former. The name has doubtless 

 been applied to the present genus on account of its hunting in 

 packs, like hounds, its fine handsome and bold appearance, and its 

 courage. 



A description of the anatomy of this genus is given by Dr. 

 Murie (P. Z. S. 1872, p. 715). The anal glands have been de- 

 scribed by Hodgson (Calc. Jouru. N. H. ii, p. 412), and the skeleton 

 by Dr. Campbell {ihid. p. 209). The strong and unpleasant odour 

 of the animal, which resembles that of the jackal, appears due, in 

 part, to the secretion from these glands.

Canis dukhunensis, Si/kes, P. Z. S. 18;jl, p. 100, 1832, p. 15 ; Bhfth, 



J. A. S. B. xi, p. 591. 

 Canis priuisevus, Hodyson, As. lies, xviii, pt. 2, p. 221 (1833), with 



liarure. 



* These were united by BJytli, Jerdon, Murie (P. Z. S. 1872, p. 720), and 

 others, and I am by no means confident that the distinctions here pointed out 

 are sufficiently constant to justify separation, but they are found in all the 

 specimeus I have been able to examine— seven or eight of C dukhiinettsis or 

 pririKBVus, and four of C. rutilans.
