@ Dromades Sharpe, Review Rec. Att. Classif, Birds, 1891, 72. Includes only the 
curious monotypic genus Dromas Paykull, of eastern Africa (including Madagascar) 
to southern India, Ceylon, etc. The single species, D. ardeola Paykull, differs from 
all other Limicole in a considerable number of characters, among which are its 
peculiar nidification, the single immaculate white egg being deposited at the end of 
a long burrow.

Tam not at all sure that the Glareole and Cursorii should be combined in one group, 
but most certainly Dromas should be removed from close association with either. _
