32 PROCEEDINGS OF THE NATIONAL, MUSEUM vol. 75 



The only adult female submitted is certainly darker than the main- 

 land bird. An adult female in the United States National Museum 

 from Java (the type locality of xanthonotus) has the top of the head 

 and nape deep mouse gray, the feathers with a rather broad central 

 &ooty black stripe; the mantle lemon chrome, the feathers streaked 

 centrally with pyrite yellow; rump lemon chrome. This is quite 

 different from the warbler green back of the mainland and Mentawi 

 bird; and the top of the head is much darker than in even the 

 Mentawi bird. Whether these differences would hold in a larger 

 series I do not know. 



The single adult male from Sipora is less heavily streaked below 

 than the Siberut males, but I believe this is an individual difference. 

 One of the Siberut males has the breast and belly strongly tinged with 

 citron yellow.

GRACULA JAVANA BATUENSIS Finsch 



Gracula 'batuensls Finsch, Notes Leyden Mus., vol. 21, 1899, p. 14 (Pulo 



Tello, Batu Islands). 

 Gracula javana cnganensis Chasen and Kloss, Ibis, 1926, p. 295. 



Four males and six females, Siberut; six males, six females, and 

 one unsexed, Sipora. 



The United States National Museum possesses one adult male and 

 two adult females from North Pagi Island and three adult males 

 and two adult females from South Pagi Island. The series from 

 Siberut, Sipora, and the Pagi Islands agree in size and color and 

 undoubtedly represent but a single form. Comparing the Mentawi 

 series with one consisting of two adult males and seven adult females 

 from Engano Island, I find the former to be slightly larger, with 

 a considerably longer and heavier bill. Undoubtedly Gracula javana 

 enganensis is restricted to Engano Island. 



Gracida rohusta of Nias is a larger bird with a much larger and 

 heavier bill and the line of feathers on the sides of the neck, separat- 

 ing the bare space below the eyes from the occipital lappets, is 

 broader and differently shaped from the forms grouped under 

 Gracida javana. In Gracula rohusta the line of feathers just re- 

 ferred to is broader above, while in the forms of Gracula javana it is
