REMARKS.—The proposal of a new species, based on a single specimen, in a genus which is important for its variable species, may be controversial, but it seems desirable to give attention to a taxon which with apparently differs from all others known in combination of characters: shape and indentation of rostrum and telson; prominence of suborbital angle;. The space, suborbital angle, and posterior spines of the telson are very different from those in the typical form of C.

Both forms have the large second chela peculiarly grooved on the extensor edge, as noted in the eastern Atlantic material by Crosnier and Forest, and at least half of the presumably eight posterior spines on the telson of the holotype of B. Six of eight have been .. recorded from the Philippine-Indonesian region and are dealt with individually below. •51. REMARKS.—As mentioned in the "Remarks" on the genus Nikoides, more than half of the 45 species of Processa have been recorded from the Atlantic, with a slight majority of them from the eastern Atlantic.

Lysmata trisetacea (Heller, 1861)
I am convinced by the current state of knowledge of the species of Lysmata that these two specimens represent a single species, especially since the anterodorsal region of the carapace appears slightly deformed in the Hawaiian specimen, as if it may have originally had three postorbital teeth. REMARKS.—Lysmatella differs from Lysmata only in the complete absence of epipods on any of the pereopods, compared with their strong development in the four anterior pairs in the latter genus. Powell of the Department of Zoology, University of Port Harcourt, Port-Parcourt, Nigeria, has informed me that he has found specimens of Merguia in high-salinity mangrove streams in the eastern Niger Delta.
In recording specimens of the latter species from Suriname, Holthuis noted that in male specimens 'the dactyl of the last three pairs of pereiopods is slender and unarmed' rather than bearing 'two posterior spines' and being 'less slender' as in the Brazilian holotype of M.
