A COLLECTION OF MAMMALS FROM SIAM. 29 



quite small, about an inch as a liaif in diameter. It is present in 

 botli tiie adult females and, wliile in one there ia a ring of bare 

 skin 9-12 inches broad right round the neck, in the last the 

 neck is entirely devoid of hair from the ears to the shoulders — a depth 

 of 20 — 24 inches! The blood-spot is apparent]}' still in the same 

 place and is (piite small in area. 



Both Major G. P. Evans' and 'Sh: P. H. Kenip2 have dealt witii 

 this curious development at some length ami offered various expla- 

 nations to wjiich I am unable to ad<l : that the sore occurs where tiie 

 smoothness of the pelage is broken on the throat and that the result- 

 ing bareness may extend over the entire neck are the only uinioted 

 details I can contribute. 



Evans saj's that the sore occurs both on Indian and Burmese 

 Sambur, and Wroughton ( l.c.s. ) records it from South Tenasserim, but 

 Kemp has not found it on animals from Pitsanulok, Central Siam, nor 

 from Peninsular Siam : it is found, though not alwaj's, in Uusa of the 

 !Malay States, but is not accompanied by the large areas of bare skin 

 exhibited by the present animals. Nobody seems to hive noticed it in 

 captive deer.
