Now Apalis nigriceps collaris van Someren, 1915 . See Urban et al., 1997: 271 . HOLOTYPE : AMNH 598889 , adult male, collected in the Bugoma forest , ca. 01.20N , 31.05E ( Polhill, 1988: 23 ), Uganda , on 16 October 1913 , by V.G.L. van Someren. From the Rothschild Collection. COMMENTS : In the original description, van Someren designated as type an adult male in the Rothschild Collection collected in the Bugoma forest on 16 October 1913 . Tied together with it and sharing a label is an immature male specimen presumably collected at the same time. Both of these birds are clearly marked as males on the original label, but one of them, AMNH 598890, has all of the signs of immaturity referred to by van Someren in his description. The sex of this immature has been incorrectly copied onto the Rothschild label as a female and Hartert (1920: 460) mistakenly referred to ‘‘Types: s ♀ ’’. It is a paratype of A. n. collaris . In the original description, van Someren referred to specimens from Mabira , Kyetume , Bugoma , and Ituri forests in Uganda . Paratypes in AMNH , in addition to AMNH 598890 , are two birds from the Mabira forest : AMNH 598891 , male, collected 5 May 1914 , and AMNH 598892 , female, collected 25 June 1914 . In his description, van Someren did not say how many specimens he had or whether he had examined specimens in the Rothschild Collection taken by others ; I have only considered van Someren specimens to be paratypes . Additional paratypes are in RMCA ( Louette et al., 2002: 39 ) .
