DIVING PETREL. 
I consider three easily separable subspecies are confused under the name 
P. garnotii, and would name them : — 
P. garnotii garnotii Lesson ; coast of Peru. 
P. garnotii lessoni^ subsp. n. ; coast of Chili. 
This form is much larger than the Peruvian bird, and has a noticeably 
heavier bill, with the inner wing-coverts grey and white-mottled. 
P. garnotii magellani, subsp. n. ; Straits of Magellan. 
This bird is easily referable to the genus Puffinuria by its bill-characters, 
and is separable from the preceding by its inferior size and the pure white 
coloration of the inner wing. 
Specimens collected by NicoU at Molyneux Sound, Smythe’s Channel, 
were named by him as typical P. urinatrix when he separated his P. dacunhm. 
But his diagnosis shows that he used an entirely different bird for the preparation 
of his specific characters relating to his new species. All the P. garnotii group 
are noticeable at sight by the distinct demarcation of the dark colouring of the 
head from the pure white of the throat. The same birds were again referred 
to P . urinatrix by the author of the Monogra'pTi, who noted their peculiarities 
of coloration, but did not recognise that they were close to P. garnotii. 
I have seen birds from Trinidad Channel, Woods Bay, and Punta Arenas which 
belong to this form, while specimens from Cockle Cove and Cove Harbour 
(Messier Channel) are referable to P. urinatrix coppingeri. 
I would note that when Quoy and Gaimard {Yoy, ‘‘ Uranie ” et “Physic.,^^ 
Zool., p. 137, 1824) introduced their Procellaria herard, they added (p. 136): 
On trouve dans les manuscrits de Commerson, sous le nom de procellarius 
falMandiuSj un petrel qui a quelques rapports avec celui-ci. Cependant il a 
le dos parseme de plumes blanches qu’on ne voit pas dans le notre.
