1 cJ, 1 2, Klong Bang Lai, Patiyu, Peninsular Siam. Jan. 1916. 

 [Nos, 2079, 2081]. 



The specimens from Krabin and Hup Bon, N. E. antl S. E. of 

 Bangkok, closely resemble examples of M, b. herdmorei from Mergui, 

 Tenasserim, taken in January, and also a series from Bandon, Peninsular 

 Siam, collected in July, which I regard as members of the same 

 subspecies ; the only constant differences being that the nnizy.Ies are 

 paler, being annulated with buff instead of ochraceous while, on the 

 whole, the three black dorsal stripes are a little less defined. 



The Patiyu specimens, coming from a locality intermediate 

 between the more northern places and Bandon and taken in January, 

 show greater differences ; the upper surface, except the muzzle, being 

 of a paler tone as, the annulations there and the yellow lateral stripes 

 are Naples yellow or creamy rather than rich buff, while the median 

 portion of the back between the light stripes is less ferruginous, being 

 Sudan brown in colour. The white under surface is strongly washed 

 with light orange-j'ellow instead of being white or washed with 

 ochraceous. 



In view of their provenance (surrounded by the others) it is 

 impossible to rank them as a local race so — though the}' were taken in 

 the same month as the Mergui specimens, which are old and perhaps 

 discoloured — I think we must regard them as evidence that tiiis race 

 of Menetes undergoes some seasonal change, though this is a thing that 

 is not so usual in the niore equatoi'ial portion of this region as it is 

 farther north. The genus is Indo-Chinese with several races occurring 

 in Siam or on its borders. 



Menetes herdmorei is a scjuirrel with a speckled upper and 

 white or 3'ellowish under-surface and may be recognised by a pair of 

 yellow stripes on each .side. Black ( or dark) dorsal, sub-dorsal and 

 lateral stripes are also generallj' present but the)- vary much in in- 

 tensity according to locality and to season. The back from shoulders 

 to root of tail is nnich richer and redder in colour between the inner 

 light stripes than is the rest of the upper surface. 

 (For measurements see table p. :il).
