like the rest of the under parts, with a small brown spot on the centre 

 of each feather. This is one of the many species to which the name 

 Falco lanarius has been given, under the supposition that it may be 

 the Lanner of the old works on falconry ; but as the original F. la- 

 narius of Linnaeus is now admitted to be the young of F. gyrfalco, 

 and as systematists are generally agreed not to trace binomial titles 

 further back than Linnaeus' s Systema, of course the specific name 

 lanarius must be dropped altogether, and the oldest binomial name, 

 Falco biarmicus, Temm., adopted for the present species. 



10. W. Tinnunculus alaudarius (Gm.). This widely diffused spe- 

 cies extends, without variation of form or colour, from Britain south- 

 wards to Central Africa and eastwards to India. 



11. N. W. Nauclerus riocouri, Vieill. 



12. Accipiter sphenurus/]\x.Y.1 Resembles^, spy^ewwrw*, Riipp., 

 in the cuneate form of the tail. Head and neck rufescent, with a 

 fuscous medial stripe on each feather ; belly white, barred with brown ; 

 back cinereous brown with rufous margins ; upper tail-covers white ; 

 tail cinereous, with three broad fuscous bars, outer feather white, 

 with five bars. 



13. N. Accipiter carbonarius (Licht.). Two specimens agree with 

 Lichtenstein's description (in his Verzeichniss einer Sammlung von 

 Saiigethieren u.Vogeln aus dem Kafferlande, 8vo, Berlin, 1842, p. 11), 

 except in having only three or four white bands on the tail instead of 

 five. With the exception of these bands, and the numerous light and 

 dark brown bands on the remiges, the plumage is wholly black ; cere 

 and legs yellow. 



Total length, 12 inches; wing, 7; tarsus, ly^^. 



14. W. Melierax gabar (Daud.). {Accipiter erythrorhynchus, 

 Sw.) 



15. Melierax polyzonus, Riipp. United by Mr. Gray to M. ca- 

 norus, Rislach {M. musicuSy Daud.), but differs in its smaller size, and 

 in having the upper tail-covers banded grey and white, while in M. ca- 

 norus they are pure white. The wing in M. polyzonus measures 12 

 inches, in M. canorus^ 15 inches. 



16. ^ . Polyboroidesradiatusi^co^.). {Falco gymnoffenySyTemm.) 



17. N. Circus pallidus, Sykes. 



18. W. Scops leucotis (Temm.). 



19. W. Scotornis climacurus (Wi&iW..). 



20. Caprimulgus infuscatus, Cretzschm., female. Agrees with 

 Riippell's plate, but wants the white wing- and tail-spots of the male 

 bird. 



21. W. Eurystomus afer (Lath.). {E. orientalise Riipp.; E. ru- 

 bescens, Vieill. ; Collaris purpurascens, Wagl.) 



22. W. Coracias abyssinica, Gm. {Coracias caudata^ Wagl.) 



23. W. Coracias ncevia^ Daud. (0. levaillantiy Riipp. ; C. nu- 

 chalis. Swains.) 



24. W. Ceryle rudis (Linn.). {Ispida bicincta, Swains.; /. bitor- 

 quata, Swains.) Identical with specimens from Smyrna and S. Eu- 

 rope. The individuals with two pectoral bands (/. bicincta, Swains.) 

 are the males.
