A bird was brought to me on September 19, which I then pronounced 

 to be a fulmar, but which 1 now believe to have been an individual of 

 this species. Unfortunately, being much occupied with other work, and 

 supposing these to be common, I disregarded it and did not preserve the 

 specimen. It never afterward came under my personal notice. Mr. 

 Eaton, naturalist of the English party, visited us on December 9, and 

 then told me that he had found a specimen, and, on December 29, the 

 specimen preserved was brought home alive by one of the men, having 

 been dug out of a very deep burrow by the dog, at a considerable dis- 

 tance inland, and well up among the hills. He found no egg. I saw 

 them following the ship on January 18, about seven hundred miles north 



of Kerguelen.

The single specimen of this bird brought home by Dr. Kidder is of special interest 

 and importance. It is of a species I never saw before, but one of which, with a degree 

 of sagacity which proves equally unexpected and gratifying, I introduced a compiled 

 account in my monograph, judging it to be, from the published descriptions, different 

 from any one with which I was then acquainted. 



The characters of this bird agree exactly with the accounts given both by Kn-hl and 

 Schlegel, II. cc, of a bird thej^ call Procellaria grisea; and there is no reasonable ques- 

 tion that all three of us have the same species in view. But there is little if any prob- 

 ability that it is the same as P. grisea of Latham, which is described as having the bill 

 two inches long, &c. (see what is said Proc. Acad. Phila. p. 148, foot-note, and p. 149, 

 text). In my monograph, I permitted "grisea Kuhl" to staud, as the names fell in 

 different so-called genera; but the groups are so closely allied, and birds of this genus 

 are so commonly called " Procellaria ", that it will tend to prevent fature misunder- 

 standing to apply to this species a new name. And, in so doing, I take pleasure in 

 recognizing, to this slight extent, the excellent service which the author of this paper 

 has rendered in extending, and especially in increasing the precision of, our knowledge 

 of southern oceanic birds.
