24 PEOCEEDIXGS OF THE NATIONAL MUSEUM Si "aoA 



Two specimens from Simalur Island {Culicicaqja ceylonensis perc- 

 nocara Oberholser) and two from Nias Island {Gulicicapa ceylon- 

 ensis pellonota Oberholser) described in the same paper with the 

 Pagi bird beIon<T apparently to one form. They agree, however, 

 in having the throat and chest darker, the breast and belly a deeper 

 yellow, the pileum darker, and the backs more yellowish than in the 

 Mentawi form. The name Gulicica'pa ceylonensis 'percnocara, stands 

 first on the page and is the one to be used, with peUonota as a 

 synonym. There is no appreciable difference in size between the two 

 forms. 



GRAUCALUS SUMATRENSIS CRISSALIS Salvador!' 



Graucalus crissalis Saxvadori, Ann. Mus. Civ. Storia Nat. Geuova, ser. 2, 



vol. 14, 1894, p. 592 (Si Oban, Sipora Id.). 

 Artamides sumairensis halistephis Obekholsek, Smiths. Misc. Coll., vol. 60, 



no. 7, 1912, p. 14 (South Pagi Id.j. 

 Coracina sumatrensis c?'lssalis Chasen and Kloss, Ibis, 1926, p. 288. 



Six adult males, three immature males, and nine females, Sipora ; 

 four adult males and four females, Siberut. 



The series from Siberut appears to be slightly darker and on the 

 average a trifle smaller than that from Sipora, but the differences 

 are too slight, in my opinion, to warrant providing it with a name. 

 I can not appreciate any differences between South Pagi Island speci- 

 mens and those from Sipora. Doctor Oberholser, in naming A. s. 

 halistephis^ apparently overlooked Salvadori's description of G. cris- 

 salis. 



Graucalus s. crissalis is the darkest of all the forms thus far 

 described from the islands off the west coast of Sumatra, with the 

 possible exception of Graucalus smnatrensis kannegieteH of Nias, 

 of which I have seen no specimens. 



VOLVOCIVORA CULMINATA CULMINATA (A. Hay) 



Cehlepyris culminatus A. Hay, Madras Journ. Liter, and Sci., vol. 13, pt. 2, 



1844 (1845), p. 157 (Malacca). 

 Lalage fimbriata culminata Chasen and Kloss, Ibis, 1926, p. 289. 



Two males and one female, Siberut. 



The males agree Avith a specimen of this form from the Kateman 

 River, E. Sumatra, in color and size. The t3^pe of Gampephaga 

 coiiipta Richmond and another female from Simalur Island are 

 darker above, the postocular stripe is broader; it is more heavily 

 barred below than in the single female from Siberut. The Simalur 

 bird evidently represents a recognizable form. A pair of Volvo- 

 civora finibriata from Java in the United States National Museum 

 are so much darker than cuhninata that I can see no utility in making 

 the latter a form of it. A. culminata is, however, evidently divisible 

 into several forms.
