ALCEDO MENINTING PROXIMA Richmond 



Aloedo menrnting proxima Richmond, Proc. Biol. Soc. Washington, vol. 



25, 1912, p. 104 (North Pagi Island). 

 Alcedo meninting Chasen and Kloss, Ibis, 1926, p. 281. 



One adult male, Sipora. 



The above specimen is more greenish above and lighter below than 

 the type of proxima; in the latter character it can be matched by a 

 female from North Pagi, but in the former there is no specimen in 

 the North Pagi series consisting of five specimens that matches it. 



Alcedo meninting callima and Alcedo meninting subviridis Ober- 

 holser,^^ from the Batu Islands and Nias, respectively, agree in being 

 much deeper blue above than A. m. proxima. They are much 

 alike; the only difference I can detect is the apparently longer bill 

 of A. m. callima, but this presumed difference might disappear with 

 a larger series. The series of A. m,. callima consists of three speci- 

 mens from the Batu Islands; that of A. m,. subviHdis, three from 

 Nias and one from Pulo Tuangku, Banjak Islands.

Ceyx rufidorsa Strickland, Proc. Zool. Soc. Loudon, 1846 (1847), p. 99 



(Malacca) ; cf. Hartert, Nov. Zool., vol. 9, 1902, p. 430. 

 Ceyx rufidwsus rufidorsus Chasen and Kloss, Ibis, 1926, p. 281 (part). 



One male, Siberut; three males and one female, Sipora. 



The United States National Museum has a male and a female 

 from the Batu Islands (Tana Bala and Tana Masa). 



The above series seems to have more of the Chinese violet wash 

 above when compared with the series in the Museum from various 

 islands in the South China Sea, Borneo, and Sumatra, though the 

 female from Sipora is as red on the mantle as Bornean birds. One 

 male from west Sumatra has as much of the purple wash as Sipora 

 birds. The presence or intensity of the purple wash must be more 

 or less individual. There appears to be no difference in size. 



CEYX DILLWYNNI Sharpe 



Ceyx dillvyynni Shabpe, Proc. Zool. Soc. London, 1868, pp. 591, 593 (Labuan). 

 Ceyx 7-ufidorsus rufidorsus Chasen and Kloss, Ibis, 1926, p. 281 (part). 



An unsexed adult specimen from Sipora, November 26, apparently 

 belongs to this species; it is quite different from C. r. j'ufldorsus 

 with which it was taken on the same day. Below it is white, with 

 an ochraceous orange band across the breast, the flanks of the same 

 color, instead of the light cadmium of C. r. imfidorsus ; the mantle is 

 black, the feathers rather broadly tipped with ochraceous orange. It
