 the second typical family of the Dentirostres, is reciprocally 

 effected by various forms belonging to the subdivisions of 

 each, which, mutually losing some peculiar characteristics of 

 the typical representatives of their own family, assume in a 

 greater or less degree those belonging to the other. Thus 

 the Short-legged Thrushes (forming SWAINSON'S subfamily 

 BracJiypodina) become nearly allied to the subfamily Lani- 

 ana, by the intervention of the genus Triclioplwrus ; and also

 species of the smaller Thamnophili, or Bush-Shrikes of Ame-
