THALASSIDROMA BULLOCKII, Fleming. 



(Bullock's Petrel.) 



By Mr. G. D. ROWLEY. 



The stream of my subject in former Numbers flowed in the direction of a 

 Duchess and an Archduchess; here it brings into presence a humbler personage, 

 and an endeavour to perform a tardy act of justice. Because a man is poor he 

 sometimes fails to receive his rights. I think we have an instance of it in the 

 present case. This bird should be called by English ornithologists Bullock's 

 Petrel, concerning which presently. 



Mr. George Robert Gray says, in his ' Genera of Birds/ vol. iii. : — 



" Thalassidroma, Vigors. 



^^ Mr. Vigors proposed (Zool. Journ.) this name in 1825, being 

 unacquainted with the fact that M. Boie had separated these birds under 

 that of Hydrolates in 1822, which name, however, cannot be adopted, as it 

 had previously been used by Vieillot. It embraces the Prince of Canino's 

 subgenus Bidweria, which was established in 1842, and also Oceanites of 

 Count Keyserling and M. Blasius, which was proposed in 1840." 



Gray gives eleven species to Thalassidroma^ and twenty- five to Procellaria, 

 Linn., " estabUshed by Linnseus in the ' Systema Naturae,' 1748. Leach used 

 Fidmarus in 1816 ; Kaup, in 1829, Rhantistes/' &c. 



Dr. Coues says that the generic name Thalassidroma must be entirely 

 suppressed, as being synonymous with Procellaria proper, and in its stead 

 proposes to use Cymochorea (Ibis, n. s. vol. iii. p. 131).
