Show 1900.] FROM SINGAPORE AND MALACCA. 751 half the breadth of those in front, is also slightly more prominent; the 4th, very small and tuberculiform, lies close behind tbe 3rd : all are granulated. In the larger individuals, the pubescence that covers both palms externally in the smaller tends to disappear from below upwards in tbe right palm ; leaving the upper margin, in the largest example, and the base of tbe palm still thickly covered, while the rest of the surface is naked, smooth, and of a white colour. In the last mentioned example, also, the space between the bases of tbe finger of the left chela has lost its hairv covering. Dim. d 10-5x7-5. d 7-75x6-25. d 7-5x6. $ 6-25x5. Length taken from base of rostrum to middle of posterior border. 70 a. CARCINOPLAX SUBINTEGER HIRSUTIOR, var. nov. Hab. Singapore ; littoral. A male, which has lost its right chelipede. This variety shows a much greater development of hair than the preceding species. The front has a fringe of long silky hairs, which spring from a line connecting the external angles of the front; and similar hairs are seen thickly placed on the chelipede and legs, more especially on the anterior and superior faces of the carpo- pro- and dactylopodites : the meri are relatively smooth. In the left chelipede the hairs extend to the tips of the fingers but not on them : these tips are brown, the rest of the fingers white, as seen through the less dense covering of hair. I may add that tbe 2nd of the four antero-lateral teeth (orbital angle included) is less flattened and more prominent than in C. subinteger. This variety is well-marked and the differences may be specific -e. g., the denser hairiness, the somewhat different 2nd anterolateral tooth, and the different coloration of the fingers ; but it is difficult to form a certain opinion from a single individual, in which, moreover, a chelipede is wanting.
