NOVITATES ZOOLOOICAE XXV. 1918. 323 



Mountains, also a male from Aiidai, Arfak Peninsula, a young bird from Humboldt 

 Bay, and an adult female collected at Korrido, October 1896, by William 

 Doherty. The latter, unfortunately in very bad condition, appears to be darker, 

 but all the others agree well with two sldns from Caj)e York. We do, therefore, 

 not hesitate to call all the Papuan birds before us Cajyrimulgus macrunts yorki. 

 From the examination of one skin from Northern Territory the supposed C. m. 

 keatsi Mathews (Novitates Zoologicae, xviii. p. 291) seems to us to be the same 

 as yorki. This would also seem to be confirmed by Oberholser, who unites 

 the New Guinea birds with keatsi, while we find it identical mth yorki, having 

 only one topotypical keatsi before us, which we cannot either distinguish. 



As we have said before, we do not, at the moment, intend to discuss the 

 continental Indian form.'* of C. wacrHrus, but we must express our doubts regard- 

 ing C. macrurus anamesus Oberholser {Proc. U.S. Nat. Mus. xlviii. p. 598, 

 described from " Singapore and Sumatra"). Though we have no specimen from 

 Singapore Islands, we cannot help doubting that a different race from that of 

 the Malay Peninsula proper inhabits it, the island being so near the mainland, 

 and because two females, collected by Ernst Hartert in Deh, Sumatra, agree 

 beautifully with sldns from the Malay Peninsula. 



Oberholser's rediscovery of Peale's name bimaculaius would result in the 

 C. macrurus umbifjuus Hart, becoming C. macrurus himaculatus Peale, if only 

 one form inhabited N.E. Sumatra aiul the Malay Peninsula. Oberholser, however, 

 is of opinion that two Malayan forms of macrurus can be recognized : one occur- 

 ring in the Malay Peninsula and Indo-China, which he argues is G. m. himaculatus, 

 C. m. amhiguus Hart, being a synonym, the other in Singapore and Sumatra, 

 which he supphes with a new name, 6'. m. anamesus, terra typica Singapore. This 

 reasoning — as has akeady been pointed out by C. Boden KJoss (Ibis, 1918, p. 

 95) — is WTong. The type of C. bimaculatus came from Singapore and not from 

 Malacca town ; apparently Oberholser is not aware that the name " Malacca " 

 is apphed in most continental languages not to Malacca town only, but to the 

 whole Malay Peninsula, and was used in the same way by EngUsh writers at least 

 during the first haK of the eighteenth century. Therefore the statements of 

 the type of C. binmciilatus coming from Singapore and Malacca agree, Singapore 

 being part of what was called Malacca. The supposed chfferences between 

 himaculatus and anamesus are merely those of size, but (cf. Kloss, Ibis, 1918, 

 p. 96) it is very doubtful if they really exist, if more material is examined. In 

 any case aruimesus would be a clear synonym of bimaculatus, both being de- 

 scribed from Singapore. If two forms exist in the Malay Peninsula, the northern 

 one will have to be called amhiguus, since C. Boden Kloss has lestricted the 

 latter name to birds from Southern Tennasserim {Ibis, 1918, p. 96).

In Cat. B. Brit. Mus. xvi. p. 538 attention has already been called to the 

 great extent of white on the outer rectrices of two males from New Britain. 

 This difference is not accidental, as it occurs also in males from Vulcan Island
