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 | 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.

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 whieh there is a transverse series on 

 the posterior margin of each segment, the granules showing else- 

 where a tendency to a similar arrangement. Head transverse-oblong; 

 eyes small, black, granulated ; channels for the reception of the 

 bases of the external antennae 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. Seg- 

 ments 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. Antennae 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 ; terminal 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 lOg 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 seg- 

 ment. 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 Gucrin-Meneville &s A. pustulatum{lconogr . 

 R. A. pi. xxxi. fig. 9) is a species of the restricted genus Armadillo, 

 perhaps A. vulgaris.
