Female like male, but has only a half band of verditer-blue across the breast, this being more imperfect than in C. cyanipectus. Average measurements from three females: Culmen, 37; tarsus, 8; wing, 59; tail, 24. Length of single female measured in the flesh, 143.

“A well-marked species easily distinguished from C. cyanipectus, its nearest ally, by the heavy markings on crown and nape, by its black bill and by the entirely different color of its under surface. Like the former species, it is strictly confined to the banks of fresh-water streams and it is usually found in the woods.” (Bourns and Worcester.)

Genus CEYX Lacépède, 1799.

Bill intermediate in form between Alcedo and Halcyon, less compressed than in the former, not grooved; culmen straight and slightly flattened; only three toes, the inner or second toe wanting; tail very short and rounded; plumage very bright, red often predominating. (Blanford.)
