Appendix masculina on second pleopod of male with deep, unarmed sinus in sinuous posterior margin. A small species, maximum postorbital carapace length about 7 mm. Color in life.—Ground color semitranslucent wdth pale greenish to bluish-green suffusion, and entire color pattern in shades of blue. Dorsal and dorsolateral portions of carapace with mottled blue but with clear dorsomedian longitudinal stripe extending from rostrum to telson; anterolateral area posterior to antennal spine wdth dark. Figure IS.—Potimirim glabra, female (carapace length mm) from Dominica station 26. blue, M-shaped mark. Posterolateral surface of branchical region with longitudinal hght stripe extending anteroventrally from level of base of abdominal pleuron and, at level of base of first pereiopod, broadening and extending anterodorsally over M-shaped mark to orbit; pair of irregular spots, one in Hght area and one below it at level of base of first pereiopod; pair of subhnear spots flanking lateral light band just posterior to expanded Hght area; larger dark spot situated anterodorsal to upper subhnear spot; posteroventral portion of branchial region with two prominent spots, more dorsal one con- tiguous with lower posterior margin of Hght band, and ventral one anteroventral to latter and situated above base of fifth leg; ventral haK of branchial region mottled with faint submarginal stripe. Tergum of first abdominal somite with two subequal, paired, rectangular bands flanking dorsomedian light band and extending ventrally almost to base of pleura; second abdominal tergum with broad anterior and very.
