PROCELLARIID^. 229 



Berthelot (Orn. Canarienne, p. 45) is really the same as this species, its 

 range in the Atlantic Ocean extends north of the Equator to the neighbour- 

 hood of the Canary Islands. 



The specimen obtained during Cook's voyage, the subject of Parkinson's 

 drawing and Solander's note, was secured off the east coast of South America, 

 about opposite the mouth of the Rio de la Plata. 



No. 14.— "Dec. 23, 1768. Lat. 37° South. 8. Parkinson" fink MS.). 

 " The large feathers of the wing, the tail, beak, and feet are black ; the 

 belly and coverts of the tail white. No. 7. Procellaria fregata " (pencil MS.). 



" Proc. fregata nigra abdomine medio uropygioque albis pedibus totis nigris. Mscr.*" {Solander's 



MS.). 



The sketch is partly in pencil outline, partly coloured. 



Whether this bird really represents Linneeus's Procellaria fregata may 

 be open to question, though I think it answers better to the description 

 than any other known species. That it is P. leucogaster of Gould, and 

 P. grallaria of Vieillot, T have little doubt. Its synonymy vinll therefore stand 

 as follows : — 



Fregetta* grallaria. 



Procellaria fregata, Linn. Syst. Nat. i. p. 212 ? Solander, MS. ; Parkinson, Icon. ined. No. 14 ; 



KuM, Beitr. p. 138. 

 Procellaria grallaria, Vieill. N. Diet. d^Hist. Nat. xxv. p. 418. 

 Procellaria leucogaster, Gould. 



The subject of Drawing No. 14 was procured in South America, off the 

 mouth of the Rio de la Plata.
