CRUSTACEA.,565of the legs of the first pair, but none on the second and thirdpairs of k>gs ; the fifth legs are scarcely longer than the fourth;and the dactyli, in both pairs, about eijiial the penultimate joint inlength. The rami of the uropoda are rather narrow ovate, and longerthan the terminal segment, slightly pubescent above and with longciliated margins. Length of the larger specimen (a male) about1 inch 2| lines (31 millim.).Cerf Island, 10 fms. (No. 232) ; two males.The description is taken from the largest specimen.This species is distinguished from most of its congeners by theform and extreme brevity of the rostrum, the armature of theterminal segment, &c.Prom P.'i podoplitludmus, Stimpson, from Hong Kong*, it is atonce distinguished by the length of the eye-peduncles and antennules.It is apparently allied to P. palmensis, Haswell, from Palm Island,which has, however, a longer rostrum with more numerous teeth,the second to sixth segments of the postabdomen carinated, &c.There are in the collection three small specimens of a species ofthis genus, also obtained at Cerf Island with P. riclitersii, which Irefrain at present from designating by a distinct specific name,although I cannot refer them to any described species. The bodyis everywhere covered with a short hispid pubescence. The rostrumis short and slender and acute, scarcely reaches beyond the eyes, andis armed above with five teeth, whereof the first is separated by awider interval and is placed on the gastric region, the second toothon the postfrontal region, just behind the anterior margin of thecarapace ; the second to sixth segments of the body are carinated(as in P. palmensis) ; on the sixth segment the carina terminates ina small spinule. Prom P. riclitersii they seem to be distinguishedby the much slenderer, more acute, and longer rostrum, and thelonger carina of the postabdomen ; and from P. palmensis, Haswell,with which, however, they may prove to be identical, by the fewerrostral teeth, &c.STOMATOPODA.1. Gonodactylus cMragra, Fabridns.An adult female is in the collection, from Mozambique, beach(No, 22-1), and small specimens from the Seychelles, 4-12 fms.(No. 194); Darros Island, 22 fms. (No. 185); and Etoile Island,13 fms. (No. 191).* This species cannot be included in Pcjkeus as recentlj defined by Mr.Spence Bate (Anu. & Mag. N. H. i. c. p. 173, 1881).
