Hirundo obsoleta perpallida Vaurie

Hirundo obsoleta perpallida Vaurie, 1951b: 15 (Hofuf) . Now Hirundo fuligula perpallida Vaurie, 1951 . See

Turner and Rose, 1989: 160.

HOLOTYPE: AMNH 559505 , adult female, collected at Al Hufuˉf, 25 °20′N, 49°34′E (Times Atlas), Saudi Arabia, on 27 November 1923, by R. E. Cheesman (no. 5044). From the Rothschild Collection.

COMMENTS: The AMNH number was cited in the original description. Vaurie (1951b: 15–18) mentioned several times that he had three specimens and gave measurements for three, including the type. Four specimens of this taxon, collected by Cheesman in November and December 1923 at Al Hufaef, came to AMNH with the Rothschild Collection. The two paratypes labeled perpallida by Vaurie are AMNH 559503, a male collected on 13 December 1923, and AMNH 559506, a female collected on 23 December 1923. The fourth specimen was apparently not in Vaurie’s hand when he named the taxon as it is not labeled perpallida by him and it is possible that it was on temporary loan at the time Vaurie was studying these swallows. The plumage is not worn, so it seems unlikely that he merely omitted its measurements. It is AMNH 559504, male, collected on 27 November 1923.

Cramp (1988: 248) placed this species in the genus Ptyonoprogne .
