Now Gymnoris dentata buchanani ( Hartert, 1921 ) . See Hartert, 1928: 198 ; Dickinson, 2003: 718 ; Fry and Keith, 2004: 42–43 ; and Summers- Smith, 2009: 810. HOLOTYPE : AMNH 717565 , adult male, collected at Zinder , 1500 ft , 13.46N , 08.58E ( Times Atlas ), southern Niger (= French West Africa , as on label), on 19 February 1920 , by Angus Buchanan. From the Rothschild Collection. COMMENTS: In the original description, Hartert designated as the type of buchanani the specimen bearing Buchanan’s field number 414. The Rothschild Collection held a single specimen when Hartert named buchanani , but he noted: ‘‘There are in the British Museum two females collected at Yo and Kuka, near Lake Chad , which must belong to this new subspecies.’’ Most recent authors consider dentata monotypic, but Summers-Smith (2009: 810) recognized buchanani .
