14. Urra Bnüxwieuir — Brünnich's Guillemot. 
Uria Troille. Briin. no. 109. 
Until the last autumn this bird was known to naturalists on the 
authority alone of Brünnich ; who, in his Ornithologia Borealis hav- 
ing described the species at present denominated the Uria Troile, 
under the specific name of Lomvia, proceeds to notice the exist- 
ence of a second species much resembling it, and which he names 
the Uria Troile: this second species is the present bird. Linneus 
originally called the first bird Alca Lomvia in his Systema Nature, 
edit. 10. (1758) vol. i. 130; but in the second edition of his Fauna 
Suecica (1761), he named it Troile. Briinnich in 1764 took up the 
specific appellation of Lomvia from the Systema Nature, adding the 
description he found given of it in the Fauna Suecica under the - 
name of Troile, and applied Troile to his new bird, referring, how- 
ever, to the. Fauna Suecica probably as authority for the name. 
From this confusion I apprehend it has arisen that both these birds 
have not since Brünnich published his work been noticed by ge- 
neral authors as distinct species. Dr. Leach on examining this bird 
ascertained it to be a distinct species; and not being aware that it 
had been previously distinguished and described by Brünnich, ex- 
hibited it at the Linnean Society as a new species, under the name 
of Uria Francsii in compliment to Mr. Frederick Franks, whom he 
then supposed to have been the person by whom it had been first 
killed. I have already had occasion, when speaking of the Pha- 
laropus Platyrynchos, to remark the accuracy in observation of 
Brünnich. 1t is but justice to attach his name to a species of 
which his claim to priority of knowledge and of communication 
is unquestionable. Latham (Synopsis vi. 330) notices this bird of 
Briinnich’s, but considers it a variety of the Foolish Guillemot. 
"The Uria Brünnichii was found in abundance in Davis's Straits,
