400 NOVITATES ZoOLOaiCAB XXIX. 1922. 



? 1123. Chaetuia sabini ogowensis Neum. = Chaetura sabini ogowensis. 



Chaetura sabini ogowensis Neumann, Bull. B.O. Club, xxi. p. 69 (1908—" Ogowe and Aruwimi Rivers 

 Loango and Fernando Po "). 



Type: ^ ad., Ntungo (Lake Onange), Ogowe River, Gabun, 17.vii.l907. 

 W. J. Ansorge leg. No. 524. 



(The author examined not less than 19 specimens, but was only able to 

 compare it with one, the type, from the typical locahty, which does not differ, 

 except by being much larger. This character, however, is probably not constant, 

 as a specimen from Sierra Leone now in the British Museum has wings of only 

 127 mm.) 



1124. Chaetuia thomensis Hart. = Chaetura thomensis. 

 Chaetura thomensis Hartert, Bull. B.O. Club, x. p. liii. (1900— Island of San Thom6, W. Africa). 



Type : Ad., Pedroma, San Thome, November 1899. Albert Mocquerys leg. 

 (Figured in Novitates Zoologicae, 1901. No less than nine specimens 

 of this very distinct species are now in the Tring Museum.) 



1125. Chaetuia ussheri benguellensis Neum. = Chaetura ussheri benguellensis. 

 Chaetura ussheri benguellensis Neumann, Bull. B.O. Club, xxi. p. 57 (1908— Benguella). 



Type : ^ ad., Blasbalk Fontein, 26. xi. 1905. W. J. Ansorge leg. No. 611. 



(Another specimen was obtained atCassualaUa in northern Angola, 30 . vi . 1908, 

 by the same collector. It agrees with the type in having a much narrower white 

 rump band, interrupted from the white abdominal band by a brown stripe ; 

 these birds would thus agree with Chaetura ussheri stictilaema, but Neumann 

 says it is paler. More material of the very rare C. u. stictilaema and of benguellensis 

 is desired, to confirm the difEerences of these forms.) 



1126. Chaetuia ussheri shaipei Neum. = Chaetura ussheri sharpei. 

 Chaetura ussheri sharpei Neumann, Bull. B.O. Club, xxi. p. 57 (1908 — " South Camaroon "). 



Type: ^ ad., Efulen, South Cameroons, 15.vii.l905 (not 15. iv. 1902). 

 G. L. Bates leg. No. 919. 



(Of this very distinct form we have now eight skins, and there is a series 

 in the British Museum.) 



1127. Miciopus willsi Hart. = Apus melba willsi. 

 Micropus willsi Hartert, Nov. Zool. iii. p. 231 (1896 — E. Imerina, E. Madagascar). 



Type : adult, E. Imerina, l.ii.l896. Rev. WiUs leg. 



(Described from a single specimen. It differs from Apus melba africana by 

 its much smaller size, not only shorter wings and tail, but narrower remiges and 

 rectrices, smaller bill and feet ! This can hardly mean anything else than a local 

 species, or rather subspecies of Apus melba. Since 1896 it has not been redis- 

 covered, but Madagascar, notwithstanding the great amount of excellent work 

 which has been done there, is not so thoroughly and exhaustively explored that 

 this may seem incredible. It must also be mentioned that no other Apus melba 

 has ever been obtained there !)
