Diagnosis.—Carapace with antennal and hepatic spines, without branchiostegal spine. Rostrum usually reaching to or slightly beyond end of antennular peduncle, dorsal margin sinuous, tip slightly upturned; armed with 11 to 16 rather regularly spaced dorsal and 3 or 4 ventral teeth; posterior 4 to 6 teeth of dorsal series placed on carapace behind level of orbital margin. Eyes large, cornea well. Figure 21.—Macrobrachium carcinus, male (carapace length mm) from Dominica station 96. pigmented. Second pereiopods of adult male subequal, robust; fingers slender, very slightly shorter than palm, gaping in proximal part, strongly crossing at tips, opposable margin of each armed near midlength (dactyl) and near end of proximal third (fixed finger) with large tooth, fixed finger partially pubescent; palm slightly compressed, more than three but less than four times as long as wide, armed with scattered spines, spines longer and less numerous near margin continuing onto fixed finger but not forming crestlike row; carpus about half as long as palm and slightly shorter than merus. Third pereiopod with propodus slightly more than twice as long as dactyl. Color pattern characterized by longitudinal dark and light stripes on carapace and abdomen. A very large species, maximum postorbital carapace length more than 90 Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original United
