5. Galerida theklae subsp. 



1 ? ad., Uio (le Uro, li. vi. \wr2. (No. 5.) 



One single specimen iu terribly worn plumage. It is imjiossible to say to 

 which form it belongs, if not to a now one. It appears to be very near to G. t. 

 superjlaa Hart, and G. t. dciclderi Erl., especially tiie former. 



0. Alaemon alaudipes (Desf.). 



1 S juv., 21. vii. 10U2. 



Moulting from the first juvenile ]iliimage to that of the adnlt bird. (No. 20.) 



7. Hirundo rustica (L.). 



2 S ad., 0. 11. vi. 10(12. (Nos. 0, i).) 



In fine spring plumage, not different from European examples. Probably 

 breeding as far south as Eio tie Oro, although Mr. Uiggenbaoh gives no information 

 on this point. As the swallow nests as far south as Mogador in Morocco, I see 

 nothing e.xtraordinary in their breeding here in the middle of the Saharan desert- belt. 



8. Motacilla campestris rayi (Bp.)- 



cJ ad., 29. vi. 1902. (No. 20.) 



In terribly worn plumage, but evidently belonging to the English race. I 

 fancy it must be a migrant which for some reason did not return to its home in 

 England for the summer, and was unfortunate enough to be met with by Riggenbach. 



9. Apus apus apus (L.). 



2 J ad., 1 juv., 11. viii. 19U2. (Nos. 34, S."), 3(i.) 



These birds are tyjiical dark European apns, and must already have been on 

 their way south, as early as August llth. 



10. Upupa epops L. 



. 1 <^, 2 ? ? (one erroneously sexed " cJ "), ~- 31- vii. 19(12. (Nos. 22, 23, 32.) 



1 suppose these birds breed at Rio de Oro. 



11. Oidemia nigra (L.). 



2 S ad., 2(1. vi. 1902 (one erroneously marked " ¥ "). (Nos. 10, 19.) 



It is strange to understand why these birds are spending the summer here. 

 They are in their black jilumage, but very strongly worn. 



12. Aegialitis hiaticula (L.). 



2 " ? ?," 7. 10. vi. 1902. (Nos. 2, 11.) 

 One iu very good jilumagc. 



13. Aegialitis alexaudrinus (L.). 



3 cJ ad.-, 1 ? ad., 7. 8. 17. vi. 19(J2. (Nos. 1, 3, 4, Id.) 

 In worn breeding plumage.
