This form of Sambar was described by Hose in the Annals and Magazine of 

 Natural History, 6 ser., vol. XII, 1893, p. 206, and the description was founded 011 

 quite a young specimen, which was said to differ from the common Indian form in 

 several particulars. Lyon (Proc. U. S. Nat. Mus. vol. 40, 1911, p. 69) sug- 

 gests that among the material collected by Dr. W. L. Abbott, there may be more 

 than one species, though he still records them all under the heading of Rusa brookei. 

 Thus »the specimens from south-eastern Borneo have a very bright and reddish colour 

 together with a conspicuous grizzling, while the specimens from western Borneo are 

 uniformly dark brownish, although the hairs are very light in colour at the base» 

 (Lyon tom. cit.). The adult specimens in the present collection seem to be inter- 

 mediate between the two colour- varietes mentioned by Lyon. Thus there is a distinct 

 reddish tint on the hairs of the lower back, but the remainder of the body is dark 

 brownish, the hairs lighter at base. Along the whole back there is a well-marked 

 black dorsal stripe commencing some distance in front of the eyes, where it is spread 

 out as a distinct area reaching as far as to the base of the horns. In the young 

 male the anterior parts of the legs are almost rufous except for a middle line 

 which is dark brown. The rufous colour is especially evident on the hind legs where 

 this colour dominates. Posterior parts of the abdomen very påle, and bordered 

 above by a narrow rufous line which separates the påle underparts from the dark 

 brownish colour of the back. Top of head extending to between the ears mingled 

 with some rufous ochraceous hairs giving a grizzled appearance.
