With a view to study .the larval and post-larval stages of the common
pshes occurring along the Madras Coast, regular plankton collections were .
made from the Sea and from the backwaters of the Cooum and Adyar
throughout the period of study. These collections contained post-larval
forms of fourteen Genera belonging to thirteen Families and a general
account of the characters of the post-Iarvre is given in this paper with
special reference to pigmentation which is one of the important diagnostic
features of the larvre of fishes
