DENDROPHASSA VERNANS MIZA Oberholser. 



Dcndroplinssa vcrnans viifia Oberholsek, Smiths. Misc. Coll., vol. 60, No. 7, 

 October 26, 1912, p. 3 (Simalur Island, western Sumatra). 



One adult male, No. 179591, U.S.N.M., from Sibabo Bay, October 

 23, 1902. 



This example agrees with others from Simalur Island, which, to- 

 gether with it, formed the basis of the present subspecies. This race 

 may readily be distinguished from Dendrophassa ^ vernans vemans 

 of the Malay Peninsula and Sumatra by its decidedlj^ larger size 

 and, in the male, darker under parts and less yellowish (more grayish 

 green) lower breast. Compared with Dendrophassa vernans meso- 

 chloa of Nias Island it is decidedly larger; the male is darker both 

 above and below, and has the olive green of the posterior lower parts 

 less j^ellowish; the female is darker, somewhat less yellowish above, 

 darker on the lower tail-coverts, and darker, less yellowish (more 

 grayish) on the remaining lower surface. 



Measurements of all our Simalur Island specimens are added below.

Treron ciirvirostra haliploa Obekholseb, Smiths. Misc. Coll., vol. 60, No. 7, 

 October 26, 1912, p. 4 (Sibabo Bay, Simalur Island, western Sumatra). 



One specimen, the type, an adult male. No. 179592, U.S.N.M., Si- 

 babo Bay, October 22, 1902. Length in flesh, 290 mm. " Iris orange; 

 naked orbital skin yellow green; bill pale yellow, base deep red; feet

This subspecies is readily distinguishable from Treron cnrvirostra ^ 

 harterti of Sumatra by its decidedly larger size, paler pileum, nape, 

 rump, and upper tail-coverts, and somewhat lighter under surface,
