 men and nostril sooty ; feet leaden, soles dull yellow." 

 — C. B. K. 



As far as can be judged without direct comjDarison, these 

 specimens are quite typical examples of P. nuchalis, for 

 which these localities form a very considerable extension of 

 range. The species found in south-western Siam, in Bandon 

 and Trang, is P. olivaceus Blyth, which differs in having the 

 chestnut on the sides conftned to a patch on the sides of 

 the neck.

" Iris dark ; orbital skin greenish yellow ; upper mandible 

 sooty, lower mandible with tbe base yellowish, the tip pale 

 plumbeous ; feet fleshy yellow." — C. B. K. 



Somewhat darker, with the stripes on the breast rather 

 broader than in the majority of specimens from the 

 Malay Peninsula ; the differences, however, are not constant. 



Setaria rufifrons. 



Malacopteron rufifrons Cab. Mus. Hein. i. 1850, p. 65.

a-c. 2 c? , 1 ? . Klong Menao, S.E. Siam. 10 Jan., 1915. 



"Iris brown; bill blackish, the lower mandible grey; 

 feet pinkish grey." — C. B. K. 



The occurrence of this species in Siam adds another to the 

 group of vertebrates which are found in Siam, Java, and 

 occasionally Sumatra but which do not occur in the Malay 

 Peninsula. Though I have not been able to compare the 

 above three birds with specimens from Java or Sumatra, they 

 conform exactly with the descriptions and agree also in 

 dimensions.
