84 MOTISE-COLOUBED SWIFT. 



"lu May, 1874, when near Vejer with two ornithologizing friends, 

 we found tliis species to be more abundant than C. apus, while curi- 

 ously enough at Algeciraz (wh.ere, as mentioned, there are countless 

 swarms of Common Swifts) I never could detect one single C. pallidus.^'' 



Two birds, male and female, kindly sent me by Col. Irby, marked 

 7th. May, 1874, Casa Vieja, Andalucia, have the following characters: 

 — Male: has all the upper parts mouse-colour, with the ends of the 

 primaries, black, and all the other feathers lightly edged with white; 

 forehead and cheeks lighter. Throat white; all the rest of the lower 

 parts more brown, with the feathers more strongly edged with white. 

 Tail deeply forked, an inch shorter than the long primaries. Under 

 wing coverts greyish, with a series of cross lines of white on the 

 shoulder. Rest of wing and under tail luteous dark brown. Length 

 6'I^Q inches. Wing from carpus to tip six inches. Tarsus, which is 

 thickly feathered, one inch. 



The female is larger, but in other respects does not differ from the 

 male. Length nearly seven inches. Wing from carpus six inches and 

 a half. 



This bird has been figured by Mr. Dresser, B. of E., but the ^^^^ 

 is, I believe, unknown to science. It is doubtless very similar to that 

 of C. apus.
