PROCELLARIIDiE. 227 



No. 12.— "Dec. 22, 1768. Parkinson" (ink MS.). 



" The head, neck, and back soot-colour, which gradually grows paler 

 on the coverts of the wings to their edges, which are bordered with white. 

 The large wing-coverts and the tail of the same sooty colour, but shaded with 

 black ; the upper coverts of the tail and the sides pure white. The beak 

 black, as are the feet, a spot of yellow on each web. P. oceanica " (pencil 

 MS.). 



Solander's MS. note reads as follows : — 



" Proc. oceanica nigra uropygii albi pennis totis albis palma nigra disco luteo. Mscr.* 



" Fig. pict. 



" Hab. in Oceano Atlantico intra Tropicos et non procul ab America australi." 



This is Procellaria oceanica, Kuhl (Beitr. p. 136, f. 1), Avho described a 

 bird in Temminck's collection, now at Leyden (Schlegel, Mus. des P.-B. 

 Procell. p. 6), and to it referred Parkinson's drawing No. 12. It is also 

 the species commonly known as Procellaria wilsoni, and is now placed in a 

 genus (^Ocea^iites) distinct from that including the common Stormy Petrel 

 (^Procellaria pelagica^. This generic name was proposed by Keyserling and 

 Blasius, and is adopted by Dr. Coues in his monograph of this family (Proc. 

 Acad. Philad.). The species thus stands as Oceanites oceanicus (Kuhl). 



The bird referred to in the drawing was obtained off the east coast of 

 South America, in the South Atlantic Ocean, opposite the mouth of the Rio 

 de la Plata. 



Parkinson, in his ' Journal,' p. 5, remarks, under the date December 22, 

 " We saw a great many birds of the Procellaria genus in lat, 39° 37' S. and 

 long. 49° 16' W.; and we also met with shoals of Porpoises of a very singular 

 species." 



The drawing is only an outline in pencil.
