about as large as the small circular tympanic cavity behind, but 
attached to the temple rather below the upper margin of the tym- 
panic cavity. ‘The upper jaw (with the sheath on) has a sharp edge 
with a broad internal groove edged on the inner side by a slight 
ridge. Palate rather concave, especially in front. The sheath of 
the upper jaw with a slightly bidentate notch in front, and simple 
straight sides. The lower jaw strong, erect on the sides, shelving, 
convex, and rounded in front, covered with a horny sheath, and with 
a central acute point. 
15. Bevuta. 
Head very large, short, covered with a thin and hard skin, over 
the orbit and other fleshy parts covered with very small granular 
scales. Nose high, truncated in front; nostrils in the upper edge 
of the horny beak. Beak of the upper jaw high, convex, with 
broadly arched dependent sides and a central notch. Lower jaw 
strong, convex in front, with a central acute sharp-edged point. 
Thorax oblong ; back three-keeled ; vertebral plates elongate sub- 
trigonal, areola of discal shields with a narrow longitudinal ridge. 
Toes strong, expanded, with transverse band-like shields, united, to 
the claws, by a narrow scaly web. Asiatic. 
Skull solid. Nose-hole square; the front and sides of the upper 
lips shelving inwards. Orbit large, oblong, subquadrangular, lateral. 
Palate flat, internal nostrils anterior, with a short oblong concavity 
behind each. Alveolar plates moderate, band-like, rather wider 
behind, rather concave. Lower jaw short, strong, convex in front, 
and wide and thick behind, with a conical central prominence and a 
broad flat alveolar edge that is broader behind and with a very 
slightly raised outer margin. 
Bellia has the large head, with dependent lips, of Damonia; but 
the alveolar surface of the upper jaw is not so wide, and the inner 
nostrils are anterior. 
BELLIA CRASSICOLLIS. 
Emys crassicollis, Bell; Gray, Cat. Shield Rept. B. M. p. 20. 
Skull (as seen through the skin of the stuffed specimen) broad, 
depressed, ovate, sides shelving outwards ; orbit subsuperior, on the 
lateral edge of the crown; crown flat, rhomboid, broader in front, 
rather produced and narrow in the middle of the hinder edge, which 
is almost as far from the back edge of the orbit as that part from 
the end of the nose; zygomatic arch short, broad, convex, forming 
part of the crown, and wider than the back edge of the orbit in front, 
not quite so wide as the front edge of the tympanic cavity behind ; 
edge of tympanic cavity rounded; sheath of the upper jaw very 
strong, and high in front and on the sides, lower margin truncated 
in the middle, and larger and arched on the sides ; the lower jaw 
strong, short, broad in front, covered with a broad horny sheath. 
Toes strong, short, webbed to the claws, covered with band-like 
shields. Feet like those of the American Emydide.
