51. PSEUDEMYS 979 
Description—Shell rather narrow, depressed but not 
very low, without definite dorsal keel. Vertebrals five, 
broader than long. Costals four, first longest, second high- 
est, last smallest. Nuchal well developed, not very narrow. 
Marginals 12 on each side, supracaudals distinct. Plastron 
large, somewhat shorter than carapace, truncate anteriorly, 
weakly notched posteriorly. Gular plates smallest, triangu- 
lar. Abdominals largest, with longest median suture. Axil- 
lary and inguinal plates well developed. Head moderately 
large, covered above and laterally with smooth skin. Upper 
jaw not hooked. Skin of neck granular and folded. Limbs 
covered with scales; anterior with five, posterior with four 
digits webbed to bases of long claws. Tail moderate. 
The neck is clove brown with several pale longitudinal 
lines on each side. The highest one of these ends on the 
temple in a large oval spot of the same color. The lowest 
and largest is continued forward across the middle of the 
lower eyelid, giving off, at the lower edge of the inferior 
maxillary bone, a branch which, continuing forward, crosses 
to the upper jaw, runs past the anterior edge of the orbit, 
turns forward at a right angle, and terminates at the nostril. 
The five similar lines on the nape are continued forward over 
the top of the head, and, besides being more or less undulat- 
ing, give rise to several short transverse branches. There 
are six longitudinal yellow rays on the forearm; one on each 
edge and two on each surface. Greenish yellow lines tra- 
verse the backs of the five fingers and four perfect toes. The 
vertebrals sometimes show black spots. All the marginals 
are ornamented with black ocelli. The plastron is marked 
with large longitudinal seal brown blotches, not at all like 
the double lines on this region in C. ornata.
