21.0 Mr. E. C. Stuart Baker on [Ibis, 



series of Suraatraii birds several have data which are not 

 reliable, being merely on dealers^ tickets witli additional 

 informatiou furnished by the pvirchaser on now unknown 

 grounds. If we accejjt average size as sufficing to 

 distinguisli races, we have the following: — 



(1) Gauropicoides rafflesi rafflesi. 



Picus rajfflesii Vigors^ Memoir Life Raffles, 1831, App. 

 p. 669 : Sumatra. 



Habitat. Sumatra. 



Average wing-measurement of 9 birds, 138 mm. (126 to 

 153 mm.) 



Of this small series the largest bears a dealer's ticket and 

 one in Lord. Tweeddale's handwriting, but it appears to be 

 an obvious Malaccan trade-skin, and the second largest 

 (with a wing of 148 mm.) is also a very doubtful one. 

 Excluding these two, the other seven have wings of an 

 average of only 134 mm, 



(2) Gauropicoides rafflesi peuinsularis. 



Hesse, Orn. Monatsb. xix. 1911, p. 192: Malacca. 



Habitat. Malacca, south of Malay Peninsula to Tenasserim 

 and S.E. Siam. 



Average wing - measurement of 39 birds, 143'5 mm, 

 (138-153 mm.) 



(3) Gauropicoides rafflesi borneonensis. 

 Hesse, toe. cit. : Borneo. 



Habitat. Borneo. 



A small bird with an average wing-measurement (16 birds) 

 of 127-5 mm (121-134 mm.) 



SASIA. 



There are two quite good species of this little Piculet : — - 



' (1) Sasia ochracea. 



With white eyebrow, and ochre or rufous back. 



-+-(2) Sasia abnormis. 



With no white eyebrow, and olive-green back.
