1 The absence of the first primary in C. cruralis anu the length of the second 

 point to the Motacillidce as the position of this genus. C. rufescens, however, 

 has a small first primary, the second being long, as in G. cruralis. The forma- 

 tion of the wing is quite different from that of Megalurus, Malacocercus, &c., with 

 which genera Strickland associated Cinclorhamphus (Contr. Orn. 1848, p. 26). 

 Notwithstanding the presence in some species of a small first primary I consider 

 this genus should be placed in the Motacillidce.
