CHAEADRIUS. 



97 



The characters which appear to be of importance in the division of the other subgenera O'l^er cha- 

 of Charadrius do not help us much in the classification of the subgenus Pluvialis ; but it 

 may be interesting to know how they are distributed. 



The black subterminal band across the tail appears in C. morinellus and C. totanirostris, 

 and to some extent in C. veredus and C. australis. 



The absence of the white at or near the base of the outer webs of the innermost 

 primaries is absolute in C. rufiventris, C. modestus, C.fdvm, C. morinellus, and C. veredus ; 

 but in C. fdvus virghiicus the brown of this part is more or less mottled with white, and 

 in C. australis the white is replaced by buff. 



The nearly black central upper tail-coverts are more or less developed in C. modestus 

 and in C. rufiventris.
