Some measurements of spirit specimens differ but little from the above, 

 I have only seen S. airidoo^salis from the northern portion of the 

 Tenasserim provinces, the species has not yet, so far as I am aware, been 

 recorded from Mergui or Tavoy, nor is it known to occur west of the Sal- 

 ween river. It abounds around Moulmain and Amherst, and in the valleys 

 of the Houngdarau and Attaran rivers.* 



S. phayrei. 



Blyth, J. A. S. B., XXIV, 1855, p. 476 ; XLIV, Pt. 2, Extra numher, p. 36 ;— Peters, 

 P. Z. S. 1866, p. 429,— Gray, Ann. Mag. Nat. Hist. Ser. 3, XX, p. 277. 

 S. hyperythrus, Blyth, J. A. S. B., XXIV, p. 474. 



This species, as noticed by Blyth, is only known to occur west of the 

 Salween. It is not, so far as I am aware, found west of the Sitoung ; in the 

 Irawadi valley in Pegu, it appears to be replaced by S. ^ygerythrus^ whilst 

 further north, around Ava, it is represented by the closely allied >S'. tlan- 

 fordij into which it doubtless passes. S. phayrei, Mr. Davison tells me, is 

 found north as far as Pah-Khyoung at the southern extremity of Kareni ; 

 (the country of the Red Karens). 



The following are dimensions of a female from Thatone :

* Error is proverbially immortal, and consequently, attention cannot be too fre- 

 quently called to the circumstance that the localities assigned to this species and to 

 many other Asiatic squirrels in Dr. Gray's lists are incorrect.
