Salvtn separated the Diving Petrel of Kerguelen Island from the well-known 

 P. urinatrix of the New Zealand seas, on account of the grey mottling on the 

 throat and flanks. His description runs : — " Similar to P. urinatrix, but the feathers 

 of the sides of and middle of the throat with a blackish subterminal grey bar ; flanks 

 mottled with grey, each feather with a grey shaft ; under wing-coverts also grey, with 

 white edges and dark shafts. Sexes alike." 



Salvin gives no dimensions, so I have not been able to determine from which 

 specimen in the British Museum his description was taken, but I have no doubt that 

 it was from a Kerguelen example ; he also includes the birds from the Crozet Islands 

 under the heading of P. exsul. 



Tristan da Cunha must also be added as a habitat, for I am not able to separate 

 the birds described by Mr. M. J. Nicoll as Pelecanoides dacunhai from P. exsul. 

 This, too, was doubtless the species observed by the naturalists of the Scottish Antarctic 

 Expedition off Gough Island (Eagle Clarke, Ibis, 1905, p. 264). 



Although Diving Petrels are not often found in mid-ocean, Dr. E. A. Wilson 

 records P. exsul as seen from the " Discovery," in the middle of September, about 

 Lat. 30° S., in the Atlantic, and again in the Indian Ocean to Long. 122° E., and as 

 far south as Lat. 51°. According to Salvin its range extends to New Zealand, 

 as he recorded two specimens in the " Catalogue of Birds," one from New Zealand
