We may remark of the scansorial birds in general that they 

 are very numerous on the American continent, and particularly 

 in the intertropical and southern regions, where they find abun- 

 dant food in the ancient and interminable forests which they 

 inhabit. The North American fauna contains examples of all 

 the five families, the typical group being, however, most plen- 

 tifully and generally distributed in the middle districts. Three 

 species only of the whole tribe are common to the European 

 and American faunae, viz. picus tridactylus*, which is the mo.st 

 northern scansorial bird, and canus {inalacolophus) Sw., which is 

 introduced into our list on the authority of Temminck, who says 

 that it inhabits the north of Eui-ope, Asia, and America : both 

 these belong to the typical family. The third species is certhia 

 familiaris, a type of one of the aberrant families. Doubts 

 existed as to the difference between troglodytes eiiropceiis and 

 hyemalis, but they have been abandoned by the latest writers. 

 The European fauna contains no example of the psittacidce or 

 ramphastidcJB.) and in America the psittacara carolinensis alone 

 passes the parallel of the south of Europe : a species of parrot 

 reaches the thirty-second degree of latitude in the north of 

 Africa. The coccyzns americanus has been recently added to 

 the list of European birds, four individuals having been killed in 

 Great Britain, consequently it attains a higher latitude there by 

 five or six degrees than it does on the other side of the Atlantic. 

 Temminck objecting to the geographical designations of a?neri- 

 canus, carolinensis eind dominiais, in which this species rejoices, 

 has named it cinerosiis, being a translation of Buffon's epithet 

 cendrillard.
