Terrapin. Pond Turtle. 
Carapace broadly ovoid as viewed above, with margin entire, 
and greatest width about opposite commisure of third and fourth 
vertebral plates at, or a trifle before, last third in length. When 
viewed laterally greatest depth of carapace about middle of its 
length, and its margin sloping gradually down behind. Ne dis- 
tinct medjan vertebral keel, except a median obsolete trace anteri- 
orly. Posterior surface of carapace sloping down a little more 
abruptly than anterior. Marginal plates all more or less expand- 
ing, especially these postero-lateral, and those at bridge most 
steep. Posterior profile of edge of carapace becoming: slightly 
curved down. Plates forming bridge all a little longer than 
broad, and their upper edges forming distinct lateral ridge which 
extends somewhat forwards and backwards. Inguinal and axil- 
lary plates rather large and more or less inconspicuous under 
marginal plates. Plates of carapace smooth and with obsolete 
strie. Plastron large, elongately ovoid, and greatest width 
falling about last 7/; in its length or opposite middle of femoral 
plates. Gular plates with a slight median anterior emargination. 
Humerals smaller than thoracic, and abdominals largest. Fem- 
orals larger than thoracic, and anals large, their posterior mar- 
gins broadly incised. Plates on plastron with distinct angular 
strie. Head short in comparison, rather small, depressed above 
and below, and with somewhat swollen appearance posteriorly, 
upper surface more or less broadly and slightly convex. Snout 
short, deep, long as deep, though its breadth greater than either, 
and in profile triangularly convex with lower sloping down 
posteriorly to mandible. Eye large, high and anterior. Mouth 
moderate, convex in profile, sloping up posteriorly, and upper 
jaw shutting over mandible with a median notch anteriorly.
