I'EUCELLARllUJi — THE PETRELS — PRIOCELLA. 



573 



Genus FRIOCELLA, Hombron and Jacquinot. 



Priocella, Homb. & Jacq. Compt. Rend. XVIII. 1844, 357 (type, P. GarnoH, Homb. & Jacq.., =Pro- 

 cellaria glacialoides, Smith). 



Char. Similar to Fulmarus, but bill much slenderer, the nasal tubes shorter, more depressed, 

 concave on top, and separated by a wide space from the maxillary unguis. 



P. glacial 



The generic name Tkalassoica, Reich. (" Syst. Av." 1852, p. iv) has usually been employed for 

 this species. But, aside from any question of priority (Tkalassoica dating L852, and Priocella 1 S44), 

 the type of Tlialassoica is explicitly stated to be the Procellaria antarctica (GiiEL.),a bird which the 

 late Professor W. A. Forbes has recently ("Zool. 'Challenger,'" Vol. IV. lss L », p, 59) made the type 

 of a new genus, Aeipetes, and which is certainly perfectly distinct generically from the type of the 

 genus Priocella. Aeipelcs, however, is clearly a synonyme of Tkalassoica.
