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 ; chelipecles and legs short and rugose. Abdomen (of 

 female) composed of only two pieces, of which one is the narrow 

 basal segment. 



113. Favus gbanulatus, sp. nov. (Plate XL VII. fig. 13.) 



Hab. Singapore ; littoral. One female. 



Carapace convex in both directions, regularly honeycombed, the 

 pits beiug 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, longi- 

 tudinally 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 the 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 granulous, 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.
