A COLLECTION OF BIEDS FEOM N. E. SUMATRA. 113 



$, Toentoengan, Deli, N. E. Sumatra, 23rd December 



1917 [No. 876]. 

 Wing. $ , 82, 79 ; 2 , 79, 79 mm. 



This species seems more constant in its characters than 

 allied species and fewer subspecies exist. These specimens 

 are inseparable from P. plumosus of the Malay Peninsula. 



158. Pycnonotus brunneus brunneus (Birth.). 



Oberholser. IT. S. Nat. Mus. Bull. No. 98. p. 46 (1917).

We have, pending a revision of the whole group, followed 

 Oberholser (loc. cit.) in regarding the form of this bird with 

 squamate pileum, reddish eyes and dull brownish undersurface 

 as referable to Blyth's race of which we have examined the 

 greatly deteriorated type. 



159. Pycnonotus erythrophthalmos cyanochrous, Oberholser. 



Smiths. Misc. Coll. Yol. 60, No. 7, p. 10 (1912). 

 Pycnonotus salvaclorii. Hartert, p. 210.

February 1918 [Nos. 1009, 1012]. 

 Wing, $ , 72, 72, 70, 75 mm. 2 , 74 mm. 

 This race, as Oberholser states, is darker above and greyer 

 beneath than the typical race from the Malay Peninsula and 

 Tenasserim. That author also says that it is smaller; but the 

 dimensions of the large series in the F. M. S. Museums, which 

 range from 70-76 mm. in wing length, do not bear out his 

 statements in this respect. 



160. Rubigula dispar(Horsf.). 



Bobinson and Kloss, p. 182 ; Hartert, p. 210.

 Wing, $ , 82, 79, 81, 78, 81, 79, 82, 80, 82, 78 mm. 

 Evidently very common.
