mens from Behring's Straits submitted to him : it was fomid in 

 Davis's Straits by Captain Sabine. Two species of cmthus 

 existing in America appear to have been confounded under the 

 name of aquaticus : one of them identified by Temminck with 

 the European species ; the other, having a much more brown 

 under plumage, is figured in ihe Fauna Boreali- Americana under 

 the name of aquaticus, but, as the author last-named has ob- 

 served, it is in reality a distinct species. It was indeed described 

 as such by Latham under the appellation of the Louisiana lark, 

 and the Prince of Musignano in adopting the specific name of 

 hidovicianus, was led to deny the existence of the true aquati- 

 cus in America. Opinions vary as to the identity of parus atri- 

 capillus with the palustris of Europe. The American and 

 European gold-crests {reguli) have also been confounded though 

 they are now held to be distinct. It is to be noticed that the 

 pari and reguli are typical examples of their respective groups, 

 the parlance or titmice-warblers belonging to America chiefly, 

 while the sylviance are mostly European warblers. Temminck 

 states that the sylvia trochilus belonging to his group of mus- 

 civores or to regulus of Cuvier, exists precisely the same in 

 North America as in Europe, but it has not as yet found a place 

 in the works of the North American ornithologists. Bomhy- 

 cilla garrula is the only one of the ampelid(B which is common 

 to the two continents, and its manners and the extent of its 

 migrations as well as its form and plumage are absolutely the 

 same on both sides of the Atlantic. The vireones which feed on 

 insects, or, when these are scarce, on the berries of the myrica 

 cerifera, are confined to the New World. Of the muscicapidce 

 several species belong to the European fauna, but there ai*e no 

 typical ones in America agreeably with Mr. Swainson's views of 

 the constituents of the family : within the tropics and in Mexico 

 we find psaris cat/anus, a typical black-cap, and todus viridis, 

 considered by him to be a fissirostral form of the broad-billed 

 fly-catchers.
