This species appears to differ much in size; the dimensions given by writers vary from 3 to 4 
feet in length, and in alar extent from 10 to 17. The measurements given are from a specimen 
in my collection. 
Bonaparte speaks of this species as being ‘‘rare and accidental on the coasts of the middle 
States.’’ According to Latham, they abound in the North Pacific, in summer, in the vicinity 
of the Kurile Islands, being attracted to these regions by the abundance of food ; they are vora- 
cious feeders and are lean on their arrival, but soon become very fat. 
There is not, to my knowledge, any well authenticated instance of this bird having been 
procured off the coast of any part of our territory ; but being described by several writers as a 
North American species I have included it. It is possible that this species has been confounded 
with some others ' y the older authors, and that probably D. brachyura, which greatly resembles 
it in plumage, . ut is smaller, and abundant off the northwest coast, has been mistaken for it.
