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. KaAcCHUGA 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 coneave. 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.

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 tym- 
panum 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 pro- 
cess wide on the upper and lower jaws. The upper jaw with a 
subcentral acute ridge interrupted in frout by a central longitudinal 
ridge, and with an acute ridge on the inner margin which is conti- 
nuous 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 
thombic, rather high in front, nearly erect on the sides; crown 
thombic, produced and acute behind, rather longer from the pos-
