DECAPOD CRUSTACEANS OF THE WEST INDIES 103 end of antennular peduncle, dorsal margin faintly convex, tip not upturned; armed mth 13 to 15 small rather regularly spaced dorsal and 2 or 3 ventral teeth; posterior 5 or 6 teeth of dorsal series placed on carapace behind level of orbital margin. Eyes large, cornea well pigmented. Second pereiopods of adult male very dissimilar and unequal; major cheliped with fingers slightly longer than palm, widely gaping, with one large tooth on proximal part of opposable margin of each finger, each finger bearing several longitudinal rows of small spinules on exterior surfaces and long, stiff hairs along cutting edges; palm strongly compressed, about two or two and one-half times as long as wide, armed with longitudinal rows of spines, those on mesial margin forming spiny crest continued in reduced form on. Figure 23.—Macrobrachium faustinum, male (carapace length mm) from Dominica station 24. fixed finger and reduced also near midlength, becoming strong in proximal and distal parts oj palm, all spines on lateral and inner surfaces almost completely concealed by dense, soft fur; carpus usually as long as or slightly longer than palm and distinctly longer than merus. Third pereiopod with propodus two and one-half to three times as long as dactyl. Color pattern usually characterized by light transverse patch on posterior part of third abdominal tergum; fingers of second perei- opod and distal podomeres of third to fifth pereiopods often con- spicuously banded; second pereiopod light colored, except for bands on fingers. A medium-sized species, maximum postorbital carapace length about 18 mm. Color in life.—Body of male almost translucent with pale yellowish or pinkish suffusion produced by widely scattered orange-red ckromatophores. Rostrum with reddish-brown stripe along lower basal half extending ventrolaterally along margin of orbit almost. Please note that these images a
