594 Messrs. G. M. Mathews and T. Iredale on some 



perceive to C. leucomelas, so that with our present knowledge 

 it seems strictly congeneric. A further examination of 

 Priofinus suggests that this is related to kuhli rather tlian 

 Ardenna, and that it would bear the same relation to hihli 

 as Priocella does to Fuhnarus. If only nestlings were 

 available we would be able to state definite relationships, 

 whereas at present we can only suggest them, though we 

 consider our suggestions are w'cU-founded and will later 

 prove correct. 



Calonectris leucomelas. 



Procellaria leucomelas Temminck and Laugier, Planch. 

 Color. d'Ois, vol. v. livr. 99, pi. 587, 1835 : Seas of Japan. 



Two specimens labelled : — 



" Pescadores Is., May 1909. Ptifinus leucomelas (Temm.).'' 



Measurements : — 



Culmen 54, wing 326, tail 151, tarsus 51, mid-toe 58 ram. 

 „ 55, „ 327, „ 148, „ 51, „ 58 „ 



These are both adult breeding birds in good plumage; 

 this would appear to be the first record of breeding birds, all 

 the previous notes and specimens referring to sea-killed 

 birds or migrants. 



In coloration these birds agree well with the description 

 given in the ' Monograph,'' but not with the figure, which 

 represents a difi'erent bird as is there stated ; our birds, 

 however, have the throat streaked as well as the malar 

 region. 



Genus Puffinus. 



Pvffinus Brisson, Ornith. vol. vi. 1760, p. 130. 



Type (by tautonymy) : Procellaria puffinus Briinnich. 



To this genus, as restricted to birds agreeing with the 

 type in the structure of the bill, legs and feet, and in general 

 proportions, we have the pleasure of adding a new species. 



Puffinus 'bannermani, sp. n. 



Adult. General coloration above sooty-black, the head 

 and neck bluish black washed with ashy, the hind neck 

 noticeably so ; the interscapular region shows feathers
