Show 1877.] CRUSTACEA, CHIEFLY FROM SOUTH AMERICA. 675 versely oblong, very much broader than long, and with a slightly reflexed posterior margin. Last four joints of the legs clothed with very stiff short hairs ; the epimeral piece or coxa of the last pair of legs with the postero-lateral angle obtuse. Length of largest specimen about f inch. Hab. Kiogo, Japan ; and Borneo. (Coll. Brit. Mus.) This species is distinguished by the granulated body and the obtuse postero-lateral angle of the epimera of the last pair of legs. Tylos spinulosus, Dana, from Fuegia, differs, as its name imports, in its spinulous body from all the foregoing species. Subfamily ARMADILLIN^E. A R M A D I L L I D I U M , Brandt.

The two specimens in the collection which I refer to this species are convex, oblong-oval, very closely and finely punctulated, and with distinct scattered granules, of which there is a transverse series on the posterior margin of each segment, the granules showing elsewhere a tendency to a similar arrangement. Head transverse-oblong; eyes small, black, granulated ; channels for the reception of the bases of the external antennse deep and well defined. First two segments of the body with the posterior margins angulated on the sides ; first segment with the postero-lateral angles subacute. Segments of the tail short, lateral margins straight and forming nearly a right angle with the posterior margins; terminal segment longer than broad, triangular, with the sides straight, subacute at the extremity, flat above. Antennse with the two terminal joints (flagellum) together not as long as the antepenultimate joint, sub-equal. Uropoda, when viewed from above, with the basal joint very small, scarcely visible ; termiual joint almost completely filling the space between the terminal and penultimate segments. Colour steel gray, variegated with yellowish white; all the segments with narrow pale margins. Length 10| lines, breadth about 5 lines. This species is distinguished by its large size, closely punctulated and distinctly granulated body, and by the form of the terminal segment. Specimens, between which I cannot find differences sufficient to warrant their specific separation, are in the British Museum, from France, Tunis, Tangiers, Malta, and Sardinia. The species figured by Guerin-Meneviile asA.pustulatum(lconogr. R. A. pl. xxxi. fig. 9) is a species of the restricted genus Armadillo, perhaps A. vulgaris. |
