NOTIOOORYS. 419 



Family MOTACILLID^. 



The Wagtails' and Pipits, which consist o£ eight genera and a 

 large number of species, are chiefly distributed in the Old World. 

 Five of the genera however — Motacilla, Anihus, Neocorys, Notio- 

 corys, and Xanihocorys — are represented in the New World, but 

 only two, Notiocorys and Xanthocorys, occur in South America. 

 When Brabourne and Chubb published their ' List of the Birds of 

 South America ' nine species were recordedj one of which is repre- 

 sented in British Guiana. 



The majority of the Pipits of America have hitherto been 

 included by most authors in the genus Anihus of Bechstein. 

 But as the species of the New World are, on an average, smaller 

 and of somewhat diflFerent appearance to those of the Old World, 

 I propose that they be generically separated under the title 

 introduced by Baird for the Guiana bird. 



Genus NOTIOCOEYS Baird. 



Notiocorys Baird, Eeview American Birds, p. 15, 1864. Type 

 N. lufescens (Less.). 



Fig. 159. — Notiocorys ahariensis. 



In this genus the bill is slender and pointed, the width at the 

 hinder portion of the nostrils is equal to about half the length of 

 the exposed culmen and the height almost equal to the width. 

 The wing has the first four outer primary-quills longest and sub- 

 equal and exceeding the length of the tertials by about 15 mm. 

 The tail is nearly square at the tip and about three-fourths the 

 length of the wing. The tarsus is about twice the length of the 

 exposed culmen. Coloration : male and female similar.
