312 Mr. C. H. B. Grant on a Collection of 



169. Micropus apus apus. European Swift. 



Hirundo apus Liun. Syst. Nat. 10th ed. 1758, p. 192: 

 Sweden. 



a. S ad. Lengototo, 6000 ft. Nov. 10. 



Total length in flesh : 7^ inches. Wing : 167 mra. 



This specimen has apparently not yet started to moult. 



Sixteen specimens collected by myself in England have 

 the "wing-measurement as follows : — Ad. ^ 176-170, one 

 fully fledged young bird 165 ; ad. ? 175-165 mm. Total 

 length in flesh : ^ 7^-7 { ; $ 7|-7| inches. 



Of two adult specimens in the British Museum collection 

 from Norway, one, a male, has the wing 172 and the other 

 (unsexed) has the wing 107 mm. ; also two adult males from 

 Hampstead have the wing 166 and 165 mm. 



[Irides brown ; bill black; feet blackish flesh-colour.] 



170. Micropus apus pekinensis. Chinese Swift. 

 Cijpselus pekinensis Swinhoe, P. Z. S. 1870, p. 435 : 



Peking. 



a. ? ad. Lengototo, 6000 ft. Nov. 10. 



h. S ad. 10 miles S.W. of Maroto, 3900 ft. Jan. 31. 



Total length in flesh : 7 & 6| inches. Wing : 164. & 

 156 mm. 



Both these specimens agree perfectly with birds from 

 Peking ; both are in moult, the wing-feathers not being 

 fully grown, which accounts for the small measurements 

 given above. 



[Irides brown ; bill black ; legs and toes black or blackish 

 flesh. Abundant.] 



In naming these two birds I have examined the whole 

 series of the " apus " group of Swifts in the British Museum 

 collection, and append the following remarks and wing- 

 measurements : — As regards Africa, the names that have to 

 be dealt with are, besides M. a. apus and M. a. pekinensis, 

 Cypselus shelleyi Salvad. Ann. Mus. Civ. Gen. 1888, p. 227 : 

 Dembi, Shoa; Apus apus carlo Kollibay, J. f. O. 1905, 

 p. 302 : Northern Tunisia; Apus apus mar witzi, Reichw.
