During a recent visit to the Paris Museum I had an opportunity 

 of examining the type of (E. sericea, concerning which I had occa- 

 sion to publish some notes in 'The Ibis' for 1875 (p. 373). On 

 seeing this type I at once recognized a specimen of (E. lessoni ! (E. 

 sericea (Less.), placed in the genus Adamastor by Bonaparte and 

 Coues, has therefore no existence as a species distinct from CE. 

 lessoni.

a. Young. Kerguelen. 



The species included in Cabanis and Reichenow's paper on the 

 Birds collected by the ' Gazelle ' (J. f. Orn. 1876, p. 329) under the 

 name Procellaria mollis, belongs here. Last year I examined in 

 Berlin the specimen brought home by the ' Gazelle,' and found it to 

 belong to this species. 



The ' Challenger ' specimen is quite young, but interesting, as 

 showing that these birds moult at once from the downy plumage into 

 the feathering of the adult bird.
