Vor, II, Pr. 11] LOOMIS—A REVIEW OF THE TUBINARES 183 
Gifford reports having seen in the same vicinity two of these 
petrels on the 10th of June, half a dozen on the 11th, three on 
the 12th, and one on the 19th. The specimen was undergoing 
a complete moult. The worn feathers of the dorsal region are 
black, with vestiges of white tips in some instances, and the 
new feathers are heavily washed with gray and broadly tipped 
with white. The throat feathers are more or less white basally. 
In some specimens these feathers are said to be wholly dark, a 
dual coloration apparently existing in this species similar to 
that occurring in Puffinus griseus and the dark phase of Puf- 
finus chlororhynchus. ‘The tarsus is indistinctly scutellated. 
In life, according to Mr. Gifford, the bill, feet, and orbital ring 
were black and the irises dark brown. 
When Fregetia grallaria is thoroughly studied, I believe that 
wear of plumage, dichromatism, and geographic and indi- 
vidual variation will be found fully to account for Fregetta 
lawrencii Bonaparte, Fregetta melanoleuca Salvadori, and the 
variations given binomial names by Mr. Gregory M. 
Mathews.*
