9. Rhytidoceros subruficollis (Blyth) ; Elliot, Monogr. 

 Bucer. pi. xxxvi. 



No. 415. Moeara Mengkoelem, river Rawas, Nov. 18, 

 1881. Irides rich reddish brown; bill white, but at base 

 streaked with green ; skin below throat sea-green, mottled 

 and marked with cobalt, then a bright cobalt line, followed 

 by a broad black band and a rich cobalt region ; legs and 

 feet black. '' Koko.'' 



This species is new to Sumatra, but having been recorded 

 from Borneo, it was quite likely to occur in the former island 

 also. The specimen sent by Mr. Forbes is in the black plu- 

 mage of the female bird ; but from the colouring of the soft 

 parts it would seem to be a young male, as he expressly 

 mentions an appearance of sea-green on the throat. Mr. 

 Elliot states that one of the characters distinguishing R. 

 subruficollis is the absence of the black bar on the throat. 

 Although I cannot detect it on the skin, Mr. Forbes seems 

 to mention it particularly in his description of the soft parts.
