The three tribes of Crabs seem still to have enough in common to justify us in keeping the old name of Brachyura in its full extent; and I have accordingly adopted de Haan's term Brachygnatha for the groups included by Ortmann in his restricted Brachyura. Following the latter writer's suggestion as to the inclusion of Thia Leach in the Atelecyclidae, it is proposed to transfer Alcock's Thiinae * bodily to that family, and Kraussia Dana is accordingly classed here. Lastly, under the heading Portunidae, there will be found certain suggestions for an amplification of Ortmann's classification, notably the establishment of a new subfamily for the genus Goniocaphyra de Man. Major Alcock's admirable series of papers on the Indian Crabs 2, containing as they do diagnoses and bibliographies for a large number of tbe species included in the present collection, make it unnecessary to give more than a very short list of references for these species. For the sake of convenience, however, a reference to the original description and, when possible, to a figure, is given, together with one to Major Alcock's work. In the case of species mentioned also in Whitelegge's report on the Funafuti Crustacea, I have included a reference to that writer's paper. Suborder BRACHYURA. Tribe DBOMIIDEA. Family DROMIID^E. Genus CRYPTODROMIA Stimps., 1858. 1. CRYPTODROMIA HILGENDORFI de Man, 1887. Cryptodromia hilgendorfi, de Man, Arch. Naturg. liii. 1, iii. p. 406, pi. xviii. fig. 4 (1887). Three males from Funafuti, one dredged in the lagoon at a depth of 23 fathoms. This latter specimen carries a big sponge. Genus DROMIDIA Stimps., 1858. 2. DROMIDIA GLOBOSA (Lam.), 1818. Dromia globosa, Lamarck, Hist. An. sans vert. v. p. 264 (1818) ; H. M.-Edwards, H. N. Crust, ii. p. 177 (1837). Dromidia globosa, de Man, Arcb. Naturg. liii. 1, iii. p. 396 (footnote), pi. xviii. fig. 1 (1887). One male from Botuma, bearing an ascidian. The tooth at the side of the carapace is rather farther back than is indicated in de Man's figure. The locality of this species has hitherto been unknown. 1 Journ. As. Soc.
