Show 204 OR. J. B. GRAY ON THE TORTOISES. [Mar. 11, acute teeth in the centre in front. The alveolar surfaces rather broad, the upper with a single triangular ridge separated by a central concavity; the lower with a single ridge parallel to the edge. The vertebral shield rugulose, with a broad flat-topped keel ; the costal shields with an indistinct central keel more prominent behind, the part above the keel rugulose, that below it smooth ; inguinal shields very wide. 6. KACHUGA BERDMOOREI. There are two specimens in spirit, purchased of Mr. Theobald, in the British Museum. The alveolar surfaces of the upper and lower jaws very wide, as wide behind as before, rugulose, tubercular; the upper one with a very strong triangular submarginal ridge ending short of the centre and in front sharply turned towards the outer margin ; the central part concave in front, and flat behind; the portion behind the ridge very broad. Lower jaw with a very strong triangular ridge stopping short of the centre, which is concave. The upper beak even on the side, with a broad triangular central nick with a slight tooth on each side; the lower with a short conical centre ; the whole surface of the upper and the outer surface of the lower grooved and rugose. The nostrils small, circular, pierced in a horny plate that edges the nose and with a lower process produced downwards, on the upper edge of the beak. Hab. ? 18. P A N G S H U R A , Gray. Pangshura, Gray, Cat. Shield Rept. p. 36. The beaks of Pangshura tecta, in a specimen in spirit, are unlike the beaks of Tetraonyx; the gape is scaly, but the lower beak is broad in front, with a rather curved hinder edge, and there is a series of more or less distinctly separate long trigonal shields below the outer margin on the hinder part of the beak. The skin on the crown is continuous, without any grooves; the skin over the tympanum is soft, with some very obscure concentric wrinkles or grooves. 1. PANGSHURA TECTA. Emys nomadicus, Theobald. A specimen in spirit in the British Museum. The alveolar process wide on the upper and lower jaws. The upper jaw with a subcentral acute ridge interrupted in front by a central longitudinal ridge, and with an acute ridge on the inner margin which is continuous in the centre. Alveolar process in the lower jaw broad, with a strong triangular ridge parallel to the margin, and with a short central longitudinal ridge. Labial edge of the upper beak simple, of the lower beak acute and bent up in the middle. Skull (as seen through the skin in the stuffed specimen) ovate rhombic, rather high in front, nearly erect on the sides; crown rhombic, produced and acute behind, rather longer from the pos- |
