CRTT8TACEA. 52714. LamlDrus (Parthenopoides) calappoides, Adams 4' White ?Two small males are in the collection from the Seychelles, 4-12fms. (No. 194).They have the carapace relatively somewhat broader and flatterthan in the typical L. calappoides from the Philippines and EasternSeas, and are possibly distinct. The specimens of L. calap>poides inthe Museum collection are somewhat more strongly tuberculatcd, butvary between themselves as regards this character.15. Eiixanthus exsculptus, var. rugosus.This designation is proposed for a female specimen obtained onthe beach at Darros Island (No. 200), which ditfers from all thespecimens of Eiuvantlms eccsculpdus {E. mammUlatus) in the Museumcollection in having the elevations or bosses of the carapace verymuch more rugose and punctulated, so that it hassomething of theappearance of a specimen of Hypoccelus sculptus. A larger femaleis in the Museum collection from Tamatave, Madagascar [Rev,Deans Cowan), from which the figure is taken. As in the specimensof the typical form of E. ea-sculptus in the Museum collection,from Australia and the Philippines, the bosses of the carapace,althongh distinctly punctulated, are never rugose, I think this formmay prove to be specifically distinct. In E. huonii (referred to in theearlier part of this <strong>Report</strong> and in E. scidptUis) there is an additionalantero-lateral marginal tooth developed between the penultimateand last tooth. Euxanthus exscnlptns (Herbst) is referred to byHofi'mann {t. c. p. 38) as occurring at the Mauritius.16. Lophactaea semigranosa {Heller).Etoile Island, 13 fms. (a small male).This species, which is apparently well distinguished by the dispositionof the granulations of the carapace, which are absent fromthe mesogastric and cardiac regions, has been hitherto a desideratumin the Museum collection. The outer surface of the chelipedcs andthe margins of the ambulatory legs are clothed with hairs, and a fewsimilar hairs exist on the sides of the carapace near the anterolateralmargins. The coloration (in spirit) is pinkish or yellowish.is17. Lophozozymus dodone (fferhst) ?An adult male, obtained on the beach at Mozambique (No. 224),referred to this species.In this specimen the front is rather narrow and prominent, withscarcely any trace of a median emargination ; the teeth of theantero-lateral margins have some indications of having borne seta',as described by Hilj^^endorf. The merus of the chelipedcs is carinatedabove, the wrist has a cristated lobe on its inner surface ; the
