352 Mr. O. Salvia's Five Montfis' Birds' -nesting 



alaribus albo brunneoque variegatis ; remigibus et cauda 

 fusco-uigris ; corpore ^infcriore reliquo albo-flavescente ; 

 iride brunuco-flava ; rostro magis virescente. 



Only about Bur-da-Rebschi or Djebel-tiar, a guauo island, 

 five miles distant from the Somali coast near Med, where we ob- 

 served six or eight pairs ; probably also on Abd-el-Kuri and the 

 cliffs of Cokotora. In November I found fledged young on Bur- 

 da-Rebschi. The flight of the adult bird is weaving, Albatros- 

 like, and not so I'apid as that of Sula fusca or the Cormorants. 

 The young birds are stupid and easy to be caught by the hand. 

 They seem to feed solely upon fishes. Not difficult to tame. 



[If not Sula cyanops of Sundeval, this species is new ! But Sun- 

 deval calls the face and naked throat simply blue, the iris "flavis- 

 sima" the beak blue, olivaceous at the tip, the feet "olive" !! The 

 Sula capensis is altogether a larger bird, and quite different in 

 the elongate form of the gular membrane, which runs down the 

 fore-neck in a narrow line. The Sula dactylatra of Lesson, 

 which I have never seen in any collection, had the feet yellow.

A flock at the end of November near Bender Gam (Somali).

 98. Pterocles alchata. (Pin-tailed Sand Grouse.) 

 The extensive sandy plains termed the Harakta, of which El 

 Tharf is one of the largest, ai-e the only localities in which we 

 met with this Sand Grouse. Like the following species, it 

 makes no nest, but scrapes a slight hollow in the sand, in 

 which it deposits its three eggs. These are laid in May, the 

 young being hatched about the second week in June. The only 

 species of Pterocles which occur in these elevated districts are
