 it may hereafter be found to intergrade with C. tricollaris.

Forbes's Three-banded Plover is the only species in the genus which combines the two 

 characters of inner web of outer tail-feathers crossed hy three dark bars and outer web of 

 innermost primaries uniform brown. It is not only without the white on these feathers 

 which is characteristic of the typical Hiaticulce, but has also no white on the forehead. 



' Charadrius indicus of Latham (Ind. Orn. ii. p. 750) is founded on the Pluvialis minima indica of 

 Brisson (Ornithologia, ii. p. 234, 1763 edition), described from a bird said to have come from the East Indies. 

 It was probably an example of Charadrius tricollaris from East Africa, but aa the colour of the forehead is 

 not mentioned it is impossible to say.
