The sesarmid crab Pseudosesarma edwardsii (Crustacea: Brachyura: Sesarmiidae) was described by De Man in 1887 as Sesarma edwardsii from "Bengalischen Meerbusen" ( = Bay of Bengal). Alcock (1900 cited from 1984, reprint edition) reported this crab from Myanmar coast, Sri Lanka, Andaman islands and Gangetic delta (without giving precise locality data).

Abstract

Polychaete species as well as their population density and month-wise variations in population has been studied at the Tolly's Nullah sewage outfall region, Koikata. Three {Namalycastis faiiveli, Dendronereis aeslurina and Nephtys oligobranchia) out of six species recorded were found to be dominant at the outfall area. In general, polychaete occurs in higher abundance (as high as 192 no./ m²) during premonsoon (February to April) period. They are found to prefer sandy and weedy substratum.
