LANCHESTER O N CRUSTACEANS [June 19, circular and complete, small; eyes very small, but not fixed; endostome deeply excavate in the middle line; exopodite of exterior maxillipedes broad, and not reaching beyond the middle of the merus; chelipedes and legs short and rugose. Abdomen (of female) composed of only two pieces, of which one is the narrow basal segment. 113. FAVUS GRANULATUS, sp. nov. (Plate XLVII. fig. 13.) Hab. Singapore ; littoral. One female. Carapace convex in both directions, regularly honeycombed, tbe pits being more distinct on the branchial regions or lateral expansions, the elevated parts covered with relatively large rounded granules ; a rather strong prominence-granulated, and with two deep sulci on either side-on the narrowed uro-cardiac region. The marginal line is regularly curved, and defined as a non-pitted, but granulated border ; edges thick, and under side of lateral expansions honeycombed, transversely concave, longitudinally convex. Front very small, appearing as a slightly upturned prominence in the anterior margin ; epistome and tip of exterior maxillipedes just visible from above. Chelipedes very rugose, with carpus just appearing from under tbe carapace; hand as high as it is long, and as thick also, in its posterior portion ; fingers shorter than hand, curved, with short decussating tips. Legs rugose and grauulous, with carpo- and propodites obtusely carinate. Maxillipedes and abdomen also granulate; the latter (in a female) with four distinct grooves, marking the segmental sutures. The rather long and narrow 7th segment, which nearly reaches the base of the maxillipedes, is partially fused on to the large, only slightly rounded, middle piece. The sternum is deeply hollowed.
