A new species of deep-water oregoniid spider crab of the genus Pleistacantha Miers, 1879, is described from the Indian Ocean. The species is distinct in possessing a prominently inflated carapace in which the median parts of the branchial regions almost meet. It can also be distinguished from its closest congeners, P. moseleyi (Miers, 1885), P. pungens (Wood-Mason, in Wood-Mason and Alcock 1891), and P. ori Ahyong & Ng, 2007, in its more elongate and less spinose chelipeds and ambulatory legs, shorter third maxilliped, trapezoidal male pleon and a male first gonopod which is relatively stout with a short subdistal dorsal papilla

Range extension and molecular taxonomy of Propeamussium arabicum (Mollusca: Bivalvia: Propeamussiidae) from Indian waters

The thin shelled pectinoidean bivalve, Propeamussium arabicum is a molluscan species originally described from Gulf of Aden. This paper records the first report of this species in Indian coast and explains the extended distribution of the species towards eastern Arabian Sea
