. Mexican, Central American, and Cuban cambari. t distance from tip on cutting edge of the im-movable finger. Carpopodite short, with a longitudinal sulcus above, granu-lated and tuberculated; tubercles forming one or two spines ondistal end of inner margin, and two other spines on lower sur-face, one on anterior margin, the other at the lower articulationwith the hand. Meropodite granulated, but almost smooth onthe larger portion of outer and inner face ; several strong tuber-cles at distal end of upper margin; inner and outer lowermargins each with a row of strong, spiniform tubercles, theouter row shorter. All the tubercles of the chelipeds appearsquamiform on account of a fringe of short, stiff hairs at theiranterior edges. Ischiopodite of fourth -pereiopods with a strong hook ; thishook has a subcompressed, broad base, and is subcompressed,but narrower at the tip, and is slightly twisted. The ischiopo-dite of the third pereiopods is without hook, and there is onlya slight, almost imperceptible elevation at its inferior Fig. I. Cambarus paradoxus, sp. n. First pleopod (right side) of male (I).a, outer view; b, inner view. Enlarged about four times. First pleopods (see Fig. i) reaching to the middle of the basesof the third pereiopods, stout, slightly curved backward ; innerand outer parts subequal, in close apposition to the tips. Bothtips curved gently backward, and slightly outward, horny;inner part, on posterior margin, at a short distance from the tip,with a strong, spiniform process, going off at an acute angle,and being longer than the two tips of this organ. Male of the second form: Tips of inner and outer parts of 6 ORTMANN sexual organs, as well as the spiniform process, not horny;hook of fourth pereiopods smaller and weaker. Female: Similar to the male, but chelee not so strong. An-nulus ventralis transversely semicircular, anterior margin con-vex, elevated, with a curved longitudinal fissure; posteriormargin with a subtriangular depression. S
