mainly differs by its mnch larger size and somewhat darker 

 colouration. The rufous cap is also darker and lacks the 

 black tips to the feathers which are so evident in cinerea. 



33. Aetliostoma rostratuiu Blyth. — 1 c? "V^ 1915; 1 

 $ -y-^ 1915. Iris: reddish brown. Wing: J^ 70, $ 67 mm.; 

 Tail: J* 57, 2 53 mm.; Culmen: (^ 16, ? 15 mm. 



34. Drymocataphus iiigrocapitatus Eyton. — 1 ? '/s 

 1915. Iris: reddish brown. Fairly common in the lovv-lands 

 of the southern parts of the Peninsula and extending as far 

 north as to about Lat. N. 10°, where it becomes very rare. 



35. Turdinus abbotti oliyaceum Strickl. — 1 ? ^7& 

 1915. Iris: brown; Wing: 74 mm.; Tail 51 mm.; Culmen: 17 

 mm. Compared with a specimen from Koh Lak in the Siamese 

 Malaya my single Perak-specimen certainly seems to be paler 

 and should therefore belong to the subspecies which has been 

 named T. abbotti olivaceum. The Koh Lak specimen has been 

 referred by me (Kungl. Svenska Vetenskapsakademiens Hand- 

 lingar, Band 56, N:o 2, p. 57, 1916) to typical Turdinus abbotti 

 Blyth. 



36. Pycuouotus plumosus Blyth. — 1 c? V'- l^l^- Iris: 

 dark brow^n. This is a fairly rare species in the northern 

 parts of the Peninsula, but in the southern portions it be- 

 comes more abundant. 



37. Pyciioiiotiis simplex Less. — 1 J" V^ 1915; 1 ^ 



20/4 1915; 1 9. 21/5 1915; 1 $ V^ 1915; 1 ^ ^^^ 1915. Seems 

 to be more abundant in Perak than the former species at 

 least to count by the number of specimens obtained by my 

 collector. 



38. Tricliolestes criuiger Blyth — 1 5 ^V* 1915. 

 Iris: black. The Hairy-backed Bulbul is generalh^ distributed 

 över the southern parts of the Peninsula. It probably does 

 not extend farther north than to Träng, where it seems to 

 be very rare.

 Iris: reddish brown. Wing: 96 mm ; Tail: 89 mm.; Culmen: 

 18 mm. Tnhabits the southern portions of the Peninsula
