of a fully formed pleurobranch above the base of the second walking legs and from the Macrophthalminae by the more oblique position and rudimentary character of the antennules and by the greater breadth of the interantennular septum. [...] In the form of the abdomen and in the possession of hairy-edged pouches indicating openings into the branchial cavity Scopimera is related to Tympanomerus while Dotilla and Dotillopsis agree in the deep sculpture of the upper surface and side-walls of the carapace. [...] In the female the cheliped is only about twice the length of the carapace; the carpus is proportionately much shorter and the chela shorter with fingers longer than the upper border of the palm The limb in consequence bears a close resemblance to that of male S. globosa but the borders of the merus and carpus are crested. [...] 317 This species and S. proximo differ from all other members of the genus by the fact that the tympana on the meral segments of the walking legs except for that on the upper surface of the last pair are longitudinally diided by a narrow ridge; the tympana on the merus of the cheliped do not share this character. [...] The upper and lower borders of the palm are rounded in both species and there is little difference in the shape of the chela; the granlation is however a little coarser in S. proxima and the teeth on the prehensile edges of the fingers are larger and sharper.
