WEST AUSTRALIAN WHITE-FACED STORM-PETREL. 
Apparently Linne did not know the bird, but simply included Barr^re’s 
bird and attached therewith Rochefort’s description. I cannot see anything 
in Barr^re’s diagnosis whereby his bird can be recognised, so that we must fall 
back upon Rochefort. The latter writer gives a figure of his bird which has the 
head and neck all round dark like the back, and has the breast and abdomen 
white. There is no resemblance whatever to this bird, but it would quite recall 
Fregetta leucogaster, save that it is figured and described with a very long, deeply 
forked tail, which prohibits its acceptance for that form. Under no circumstances 
could it be deemed applicable to this delightful little Petrel, which is not ^^paulo 
minor P. pelagicaP This species was first described by Latham as noted above. 
It will be seen that he did not have a specimen, but depended entirely upon 
the drawings ; the second drawing mentioned by Latham is of Fregetta leucogaster 
Gould, which was accepted by Solander as P. fregata Linne. Solander’s beauti- 
ful description of his P. cequorea is herewith given : —

been determined ; the type-locality of Solander’s specimen described above.
