Vor. II, Pr. IT] LOOMIS—A REVIEW OF THE TUBINARES 9 
tion,” the specimens including the Gould Australian collec- 
tion and the spoils of the United States Exploring Expe- 
dition, reported upon by Peale. In the first three parts of his 
monograph, Dr. Coues was under the spell of Bonaparte’s 
great name, but in the two final parts he emancipated himself 
from this influence. The vulnerable points in the monograph 
are chiefly of the kind incident to lack of specimens and out- 
door observation. Dichromatism was mistaken for age varia- 
tion, and inconstant characters were sometimes misconstrued 
to be constant ones. Seasonal variation due to wear of plum- 
age, however, was clearly understood. Although other mono- 
graphs have since appeared, the influence of this monograph 
has not ceased. It “must always be consulted,’ remarks Mr. 
Salvin, “by those wishing to master the intricacies of this 
complicated subject.” Dr. Coues’s connection with the group 
did not wholly terminate with the publication of his mono- 
graph. He edited the “Ornithology” and was joint author of 
the “Oology” of Dr. Jerome Henry Kidder’s Contributions to 
the Natural History of Kerguelen Island (1, 1875, II, 1876), 
and he identified the birds of Dr. Thomas H. Streets’s Con- 
tributions to the Natural History of the Hawaiian and Fan- 
ning Islands and Lower California (1877). In Remarks on 
certain Procellarude (The Auk, 1897), he introduced the 
system of classification for the higher groups followed in the 
present paper, and in the fifth edition of his Key to North 
American Birds, printed in 1903 nearly four years after his 
death, he devoted upwards of twenty-six pages to the “Order 
Tubinares: Tube-nosed Swimmers.” 
In 1870, in Fauna Vertebrata nell’ Oceano, Professor En- 
rico Hillyer Giglioli gave an account of the species of ‘“‘Pro- 
cellariadee” observed by him during the voyage of the Italian 
corvette Magenta round the world, including five supposed 
new species originally described by himself and Count Tom- 
maso Adlard Salvadori in 1868 in Volume XI of Atti della 
Societa Italiana di Scienze Naturali. In 1876, in Volume I 
of Mr. George Dawson Rowley’s Ornithological Miscellany, 
appeared two articles from the pen of Mr. Osbert Salvin, en- 
titled Critical Notes on Procellarude, the first dealing with 
Parkinson’s drawings and the second with the petrels de- 
scribed as new’ by Giglioli and Salvadori in the paper cited
