(vide Bull. B. O. C. vol. xxxiii. pp. 56-59). On that island 

 and on Allegranza the new Chat (Saxicofa d. muriela), 

 recently figured in ' The Ibis/ was discovered. 



Dr. H. O. Forbes showed a number of slides illustrative 

 of the bird-life on the Guano Islands off the coast of Peru, 

 taken during 1911, 1912, and 1913. The chief species 

 shown were : — 



(1) Molina's Pelican (Pelecanus thagus). A set of 

 slides showing the nesting-ground, with the birds upon their 

 nests, the unfledged young, and immature birds in various 

 stages from the nestling to the fully-feathered condition. 



(2) The White-breasted Cormorant (Phalacrocorax 

 bougainvillii) — a species belonging really to the Antarctic 

 region which had strayed north with the cold Humboelt 

 Current. Several general views of the nesting-grounds 

 of this species on the Chincha, Pescadores, and Asia Islands 

 were exhibited, showing the enormous nesting-assemblages; 

 also 12 slides portraying the nests with the incubating 

 birds, the fledglings, the more mature birds, and the 

 remarkable "streams/' millions in number, in which this 

 Cormorant leaves for and returns from the feeding-areas 

 out at sea. 



(3) The Brazilian Cormorant (P. vigua) showing its nest 

 on rocks — feathers, bones of bird?, and seaweed being used 

 as building-material. 



(4) The nesting-habits of the Neboux's Booby (Sula 

 nebouxii) were illustrated by 18 slides, showing the sparse 

 manner of nesting on the " pampa/' the nests, and the 

 young in various stages from the fledgling to the first 

 full plumage, when the birds were able to provide for them- 

 selves. 



(5) The Variegated Booby (Sula variegatu) . This species, 

 though so similar to Sula nebouxii, has a very different 

 nesting-habit ; its nest was invariably placed close to the 

 top of the cliffs overhanging the tea or on ledges on 

 their face. Although they are distributed all along the
