[Eead 17th June, 1886.] (Plates I.-XIX.) The Crustacea described in the following pages are mostly The Collection contains no fewer than 166 species, 38 of which are new to science, i e nearly a fourth of the whole number They are represented by about 1060 speci- littoral species mens, in an excellent state of preservation new to the 118 species are Eauna of the Bay of Bengal (including Ceylon, the Nicobar Islands, and Singapore), only 48 species in the Collection having been previously recorded from that part of the Indian Ocean These numbers are highly surprising, as the of Bengal has been explored, years ago, by many naturalists Large carcinological collections were made in former times by French naturalists on the coast of Coromandel and at Ceylon, and a still larger number of species were collected, in the years 1857-59, by the famous ISTovara Expedition, at the same In the Eeport localities and especially at the Nicobar Islands published in 1865, by Prof Heller on the Decapoda and Bay ' ' Stomatopoda collected during that expedition, no less than LINN JOUBN zoology, VOL XXII — ! DR J G DE MAN ON THE PODOPHTHALMOUS 109 species were enumerated from Madras, Ceylon, and the ScarcelyNicobar Islands, a fifth of which were new to science more than a fourth of these 109 species occur in the Mergui The Decapodous and Stomatopodous Crustacea in Collection Mergui Collection that are new to the Eauna prove to be about two thirds of the The species number of species hitherto known as inhabiting it therefore of th«se two groups now ascertained to occur in the Bay amount to nearly 300 These numbers are eloquent and demonstrate that the collection made by Prof Anderson is a most interesting one, and this interesting of the Bay of Bengal !

CRUSTACEA OF THE MERGTJI AECHIPELA&O This fact leads me to exists regarding the direct attention to the confusion that still synonymy phthalmous Crustacea of many common Indian Podomay be accounted for This circumstance by the fact that sucb authors as Milne-Edwards, de Haan, and Dana, when describing species of former carcinologists, e g of Fabricius and Herbst, had neither studied nor examined their typical specimens, preserved in the hagen, and BerHn descriptions and ; Museums of Kiel, Copen- although the diagnoses of Fabricius and the figures of Herbst were often too short or insuf- enable the species to be satisfactorily recognized ficient to A renewed examination of the typical specimens of these older carcinologists, so far as they are still available, appears to me most desirable I have made a beginning in to be this direction by examining the types of certain species described by Fabricius, Milne-Edwards, and some others, so far as this was necessary for the present Eeport and I am now occupied with a critical study of the Australian species which were described about twenty years ago by Mr Hess I have given in the present Eeport some results of these studies, which I think will prove to be of value and contribute to a more exact knowledge of the common Indian ; I have also pointed out the distinctive characters of Decapoda, Menippe Rumpliii, Fabr,, and of Myomenippe granulosa, A M.Edw., both common species of large size, but which nevertheless were insufficiently known I have furthermore given new and common full descriptions of four species of Gelasimus, and have elucidated the characters of the little-known group of Metaplaoo and those also of many species of the genus Sesarma, which are so extremely difficult to distinguish that great confusion regard- ing them is still observable in carcinological works The Collection made by Anderson contains, as already I would especia new form of the ally call attention to the following species rare Maioid genus Harrovia, two rare species of Leptodius (L nudipes and L cavipes), two species of Seteropanope a large series of Goniosoma merguiense and of Gelasimus;
