Report on a small collection of Mysidacea from the northern region of the Malacca Strait



A list of the 18 species represented in the collection is given. Of these, two are here recorded for the second time, namely, Anchialina parva Ii and Pleurerythrops inscita Ii. The female of the latter was hitherto unknown and is now figured. li's suggestion that Gastrosaccus philippinensis W. M. Tattersall might be synonymous with G. bengalensis Hansen proved to be correct on re-examination of types material of both. One species, Acanthomysis ornata, with very aberrant armature of telson and uropods, is new to science and is fully described and figured.
