This specimen labelled “ Falco peregrinator ” is doubtless the 
one referred to in Strickland’s note appended to the translation of 
Sundevall’s paper on the Birds of Calcutta. He there states that he 
possessed a specimen which he referred to F. peregrinator procured 
in 1833 onboard ship between Mauritius and Madagascar. Other ex- 
amples, with which this one agrees, have been procured in the same 
seas under similar circumstances {cf. Gurney, Ibis, 1869, p. 445).
