444 On Birds obtained at Madeira. 



one of these was shot, hut it fell over the cliff and was lost. 

 We returned to Madeira the same evening, and the birds 

 obtained were the following : — 



1. Crithagra butyracea. 



2. Linota cannabina. 

 A nest with young. 



4- 3. Thalassidroma bulweri. 



We caught a number of pairs in holes among the stones, 

 but they had not yet begun to breed. Bill and feet black ; 

 tarsi greyish pink. Iris deep brown. 



- 4. PUFFINUS KUHLI. 



Also paired, but no eggs. They defended themselves fiercely 

 and bit with great power. Legs and feet pale pink, outer 

 toe and web dusky. Bill dull yellow, darker towards the 

 tip. Iris dark brown. 



J 5c PUFFINUS OBSCURUS. 



Only one specimen caught, an adult female, which had 

 not bred. It seems curious that at Porto Santo, which is 

 only about forty miles distant, this species had not only bred, 

 but that some of the young were in nearly adult plumage. 

 The bill is lead-coloured ; the outer toe, sole, and back of 

 tarsus black, rest livid. Eye dark brown. 



We were unfortunate in obtaining no specimens of either 

 (Estrelata mollis or Pelagodroma marina. 



6. Larus leucoph^us. 



C. Specimens from Lime Island, Porto Santo. 

 The three islands of Porto Santo lie north-east of Madeira, 

 and, like the Desertas, consist of three main islands, from 

 one of which, known as the Lime Island, we obtained some 

 interesting specimens. This island contains lime-quarries, 

 and supplies all the lime used for building purposes in 

 Madeira ; before their discovery it had all to be brought 

 from great distances by ship, and was so expensive that the 

 older houses in Funchal are built with mud and merely faced 

 with lime. The two birds obtained were : —
