The Turnstones are so nearly allied to the Plovers that it is doubtful whether they ought 



to be generically separated from them. They appear to form a connecting-link between 



the genera Vanellus and Tringa. They agree with the former in having the nasal aperture characters. 



extending beyond the basal fourth of the bill, and with the latter in having the toes cleft to 



the base. These two characters are sufficient to diagnose the genus. In the distribution of 



the colours on the rump, upper tail-coverts, and tail, as well as in the position of the nostrils, 



they resemble Vanellus, but in the character of their feet as well as in the glossy appearance 



of their eggs they resemble Tringa.
