Characters of Xenocarcinoides, n. gen.:- Bostrum long, compressed, above faintly grooved and notched at the tip, below hollowed and bearing on each side a thin wing. Carapace elongate-triangular, bearing large tubercles. Eyes moveable but not retractile, sunken in a pit formed by the side of the rostrum and the immoveable second joint of the second antenna. No pre- or postocular spines. Antenna with 1st and 2nd joints fused, subtriangular. Flagellum hidden under rostrum. Third maxilliped with the meropodite subquadrate, as broad as the ischiopodite, and bearing the carpopodite at its inner angle. Chelipeds large ; longer than either of the last three pairs of legs. (The second pair of legs are unfortunately wanting in the specimen.) The last three legs diminish gradually from before backwards. The dactyles are somewhat sickle-shaped, toothed below, and as long as tbe preceding joint. The abdomen of the male is six-jointed, owing to fusion of joints 5 and 6, between which, however, a furrow can still be seen. Tbe genus differs from Xenocarcinus White in the shape of the carapace and rostrum, and in the larger size of the chelipeds. 7. XENOCARCINOIDES ROSTRATUS, n. sp. (Plate XL. fig. 1.)
