The Double-crested and the Florida Cormorants are very nearly allied, their forms, and the structure of their plumage, being precisely similar. There is, however, a very considerable difference in size, as will be seen on comparing their measurements and average weights as given by me. The bills are similar in form, but their colours differ, as do those of the eyelids; but in the breeding season these birds may readily be distinguished by the temporary tufts or crests behind the eyes, which in P. floridanus consist of a mere line of single feathers curved downwards, while in P. dilophus they are of considerable breadth, and composed of about forty recurved feathers. In the absence of the crests, the difference in size affords the principal means of distinguishing them.

PLATE CCLVIII. Adult Male and Young Female.
This species, which is of rare occurrence in any part of the United States, is scarcely ever found farther south along the coast than the State of Maryland. I had never seen it in the flesh, until I went to Boston in 1832, when I found specimens of it in the market late in September. An old gunner in my employ brought me eight or ten in the course of a month, but they were all young birds. From one of them my son drew the figure in the plate. While I was at Pictou Professor MacCulloch presented me with a pair of adult birds in beautiful plumage. When we were on our way towards Labrador, the fishermen and inhabitants of the Magdeleine Islands, who gave the name of Curlews to the Godwits, assured me that this species breeds there in some marshes at the extremity of the principal island, and that they were in the habit of killing them as soon as they were able to fly, when they were considered excellent food. We saw none, however, on our voyage farther north, and in Labrador and Newfoundland nobody seemed to know them.
My young friend Thomas MacCulloch, who gave me, in London, several well-mounted specimens of this species, in the spring of 1835, confirmed the assertions of the people of the Magdeleine Islands, and informed me that these birds breed at times on Prince Edward’s Island, from which they spread along the coast of Nova Scotia, where they remain until very severe weather comes on, when they suddenly disappear.
I have tried to give a good figure of the adult, and that made by my son will, I hope, be considered faithful by those who are acquainted with the bird in its autumnal plumage. The adult has been represented as lying down, in order to shew the difference between this species and the Limosa melanura of Europe, to which it is allied, but from which it may readily be distinguished at all periods by the black colour of the inner wing-coverts. In the European bird these feathers are white, and the species does not occur in the United States, perhaps not in any part of North America. The females are rather larger than the males, but nothing is known respecting the nests or eggs.
