Basileuterus vermivorus olivascens Chapman

Basileuterus vermivorus olivascens Chapman, 1893: 343 (Princestown, Trinidad).

Now Basileuterus culicivorus olivascens Chapman, 1893 . See Chapman, 1894: 24–25; Hellmayr, 1935: 500–501; Curson, 2010b: 793; and Lovette et al., 2010: 765–766.

HOLOTYPE: AMNH 58974, adult male, collected at Princestown, 10.16N, 61.23W (Times atlas), Trinidad, on 1 March 1893, by Frank M. Chapman (no. 2770).

COMMENTS: In his preliminary description of olivascens, Chapman listed only the holotype, giving its AMNH number and noting that his paper on the complete collection had been delayed and the collection would be fully documented later. Chapman (1894: 24–25), in his paper on the entire Trinidad collection, reported that he had six specimens from Trinidad. These would have been available to him for the earler paper, and I consider the five additional specimens paratypes of olivascens (ICZN, 1999: 76, Art. 72.4.1). These paratypes are: AMNH 58975–58979, two males, three females, collected at Princestown in March 1893, by F.M. Chapman.
