old nests on rocks and prominent hills along the coast. Once 

 on the island of Debir I found a nest on the roof of a de- 

 serted fisherman's hut. Another stood on the vaulted ceiling of 

 an old cistern near Aualites, in the neighbourhood of Zeila. 



The nest is built of strong dry branches and boughs, is nearly 

 cylindrical, from two to three feet high, very strong and solid, 

 and above rather flat. The lining consists of smaller branches, 

 algiB, seagrass, and fungi. Abu-ketdf, Arab. 



6. Helotarsus ecaudatus. (A., D.) 

 Mountainous districts of Somali. 



7. Falco ELEONORiE, Falco concolor, lliippell. 



Island of Barakan in the Red Sea. Old mule : of a uniform 

 blackish schistaceous grey, with the throat pale, iris dark brown, 

 lores and naked space round the eye sulphur-yellow; beak 

 bluish-corneous, yellowish at the base; feet deep-yellow, nails 

 blackish-corneous. Wings 8" longer than the end of the tail. 

 Measurements (taken from fresh birds) : toe 12"; wing 10" 2"'. 

 Younger bird: ground-colour dirty brownish-black; throat very 

 pale. Young : above dark cinereous, margins and tops of plumes 

 ferruginous; below rufous with dark longitudinal spots along 

 the shafts; throat pale; beard very distinct, dark blackish. 



One adult specimen from Dahalak shows darker stripes on 

 the back ; but these are not so distinct and well-marked as in 

 F. ardesiacus, V. The throat was in this specimen of a dirty 

 whitish colour. 



I found this fine falcon not further north than 16°, on naked 

 rocks and coral islands, in the archipelagos of Dahalak, Hanakil, 

 Amphila, near Has llachemeh and on Bur-da-Rebschi. It lives 

 there during the breeding-season (Aug. to Sept.) in pairs, feeding 

 upon smaller birds and locusts, of which latter it tears out the 

 legs on the wing, like F. rufipes. Both sexes had breeding-spots. 

 On the 30th of August I discovered four breeding pairs on a rock 

 near the island of Dahalak el Kebir (15° N.L.), and found three 

 nests, which were placed very artlessly on the rocky precipice. 

 One contained three, the two others each two eggs. In size and 

 colour the eggs were intermediate between those of F. eesalon and 

 F. suhhuteo. Bonaparte (judging from his description of this
