Summary
The distribution of the different varieties ofPtychodera flava on the east coast of South India is described, along with an account of the five varieties of this species occurring in the different regions of the Krusadai group of Islands in the Gulf of Mannar.
An examination of the surface currents in the Bay of Bengal and the Indo-Pacific region of the Indian Ocean, during the breeding season ofPtychodera flava (when its larvæ are in the plankton) suggests the probable course of distribution of the species, from a starting point near about the Maldive and Laccadive archipelago.
