PROCELLARIID^. 333 



This drawing, which is roughly executed and tinted in dark brown, 

 appears never to have been certainly recognized. Kuhl says (Beitr. p. 145) 

 that he could not decipher the name inscribed on it. This I cannot under- 

 stand ; for it is plainly written. 



Bonaparte hesitatingly refers it to Q^strelata mollis (Gould). Gray, 

 with doubt, places it near (E. mollis as a distinct species, but gives as its 

 habitat the Pacific Ocean — clearly a blunder, so far as the evidence on the 

 drawing goes. 



With the types of Signor Giglioli and Count Salvadori's Q^strelata 

 armingoniana before me, I have little difficulty in recognizing the long-lost 

 Procellaria sandaliata, Solander. The drawing, however, may lay claim to 

 represent the White-breasted Petrel of Latham, who, in his ' Synopsis,' states 

 that such a species existed in the collection of Sir Joseph Banks. This might 

 be considered to refer to a specimen ; but in the ' General History ' Latham 

 uses the words " From the drawings of Sir Joseph Banks." Now, as no other 

 drawing at all answers to Latham's description, the inference is that it must 

 be considered to represent the White-breasted Petrel, and hence Procellaria 

 alba of Gmelin, who, in this as in so many cases, affixed a Latin name to 

 Latham's description. 



There are some points connected with Latham's description w^hich do 

 not quite agree with the drawing and Solander' s brief diagnosis, but which 

 are to a considerable extent lessened by comparing the specimens of 

 CEstrelata armivjoniana with the text of the ' Synopsis.' The chief discrepancy 

 lies in the colour of the legs, which Latham describes as " black-brown, the 

 fore part of the toes halfway black ;" whereas the note on the sketch says, 

 " the legs and upper part of the feet pallid white, where marked off^ pallid 

 brown," rendered in Solander's MS. " pedibus albidis palma antice nigra." 

 Both descriptions clearly point to a species of CEstrelata ; and the diff'erence, 

 being one of the perishable colour of soft parts, is not of much consequence.
