and the pteiyguids are more parallel ; but these may be taken for the 

 present as coming within the range oi individual variation. 



Measurements. See table p. 217. 



iSpecimens examined. Three, the cot\-i)es and another adult 

 iemale from iluang Prae in tlie dull phase. 



Ju'iifn-ls. The two dull examples from North Siam were taken 

 in May and are exactly alike, but the traces of bright colour occurring 

 on limbs and under surface of tail indicate, I think, that thej' possess a 

 bright ))hase and that the specimen from near ivorat, taken in Sep- 

 tember, is merely an example of this and not a distinct race. 



At; my retpiest Mr. Oldfield Thomas has compared one of the 

 Muang Prae specimens with the type of liis Mioujos aaropaadatus 

 lirmanicus in the Natural History Museum ; he writes " It does not 

 appear to be hifmanicm being distinguished by its reddisli head, this in 

 the Burma species being concolor with the body as in the ordinary 

 Indian Mongoose. I think we should now use a binomial iov birtii'iid- 

 cus". 



More recently the Indian Museum has lent me an example of a 

 Burmese Mongoose obtained at Sawadi. The skin is somewliat frag- 

 mentary but it agrees with Mr. Thomas' statement in having no red on 

 the head. The pelage is shorter and less harsh than in the Siamese 

 animals but the soft under-fur is much denser while the annulations of 

 the longer dorsal hairs are much narrower, deep buif in colour and only 

 two in number. 



The Burmese skull is a little smaller than the others but its 

 post-orbital breadth agrees with the Lat Bua Kao example: its only 

 other differences, apart from size, seem to lie in the closer approximation 

 of the buUtc, which also diverge rather less posteriorly ; the smaller 

 size of the foramen magnum ; and the narrow, parallel-sided interpter^'- 

 goid space. The teeth are similar except that p' and m' are shorter 

 and more compact. 



Muuijos siamensis is probably closely allied to }[. i-alirifivns of 

 Hainan, which 1 only know from descrption ( Allen, Bull. Amer. Mus. 

 Nat. Hist., XXVI ( I'.tU'J). p. 21(1-2) and of which the external dimen- 

 sions seem very similar save for a larger hind-foot (GO mm., s. n ). The 

 Siamese form, however, is not grey in colour and has no shade of oliva-
