A COLLECTION OF BIRDS FEOM N. E. SUMATRA. 75 



The second bird is an adult male, undoubtedly of this 

 species, though it does not quite agree with the description of 

 the type, differing as follows. Upper lores grey, superciliary 

 stripe black posteriorly, the feathers with white bases. A 

 narrow black band starting at the nostrils completely sur- 

 rounding the eye. Beneath this, starting at the chin, a broad 

 silky white band ending at the ear coverts, which are silky 

 white ; this again is bordered by a black band. The feathers 

 in the centre of the throat black with white bases and ulti- 

 mately white with black tips. A clearly defined narrow black 

 band separating the black and white throat from the olive 

 brown breast. Wing 142 mm., tail 57, tarsus 44, bill from 

 gape 26 mm.

 1916, 29th January 1917 [Xos. 731, 740, 643, 648, 

 752, 667, 769, 672].

These specimens which are very uniform inter se agree 

 with specimens from the Malay Peninsula and must we think 

 be regarded as belonging to the continental form of the spe- 

 cies, E. chinensis chinensis. They differ from the insular 

 form E. c. lineata (Scop.) which is recorded from S. & W. 

 Sumatra, in being much lighter in general colour and in 

 having the back in the male much less blotched with black. 

 We have compared the males with a specimen of E. c. lineata 

 from Paku Saribas, S. W. Sarawak, Borneo. 



3. Gallus galhis(Linn.).

 ruary 1918 [Xos. 995, 6, 1026-8].

Agree exactly with a series from the Malay Peninsula and 

 have large white lappets on the sides of the neck.
