The natatores, like the cetacea which they represent, in- 

 habit the waters, the majority seldom coming ashore except 

 for the purpose of nidification ; and they are mostly common 

 to the two continents, especially the marine ones. The generic 

 groups are almost entirely the same in the same parallels of 

 latitude ; and even where the species are peculiar, there is a 

 surprising uniformity in the numbers of each group, as may be 

 observed on consulting the table in page 167- The common white 

 pelican of America is considered as distinct from the onocro- 

 talus of the old world by Mr. Audubon, and some occasional 

 differences in the bill are pointed out in the Fcnma boreali- 

 americana ; but in most other respects the American and Eu- 

 ropean pelicans have a very close resemblance. The breeding 

 plumage of many of the northern gulls is still very imperfectly 

 known, and the exact number of species and their distribution 

 will remain uncertain until some ornithologist, who has the re- 

 quisite opportunities of observation, accomplishes a revision of 

 the genus. The characters of the black-headed gulls especially 

 require elucidation. 



In concluding our remarks on North American ornithology, 

 made chiefly with a view of pointing out its peculiarities, by 

 contrasting it with that of Europe, we may refer the reader to 

 the Pi'iuce of Musignano's " Specchio comjiarativo" * , &c.,
