ART. 4 BIEDS OF THE MENTAWI GROUP RILEY 9 



The specimens from Siberut and Sipora, apparently do not differ 

 from birds from Nias and Simaliir. The pure white of the lower 

 abdomen and anal region given by the describer as one of the char- 

 acters of this race does not hold, specimens with these parts as de- 

 scribed and others having them tinged more or less strongly with 

 Isabella color occurring in the above series. The race can be main- 

 tained, however, as a sort of intermediate between chinensis and 

 javanica; smaller than the former and somewhat larger than the 

 latter. 



In my report upon a collection of birds from Celebes ^^ in com- 

 menting upon this race I made a slip of the pen in saying A. p. 

 cleptea is smaller than A. /;. javanica', it is actually larger. Since 

 that paper was written the National Museum has received a number 

 of specimens of the Chinese race; all large birds.

One female, Siberut, September 12; one male, Sipora, Novem-

These two specimens have the white rumps of N. p. phaeopus, but 

 seem to have longer bills; it is possible there are more than two 

 forms of the species. 



The culmen of the male measures 85 ; the female, 95 mm.
