Oxoplecia gen. nov. 
1. Small specimen, viewed from the front, to show sub-rectangular fold and 
sinus. 
2. Side view to show beak of the largest specimen found. 
3. Cardinal area of the same specimen as fig. 2. 
4. Cross-section of the rostral portion of specimen shown in fig. 1, to illustrate 
the bifid cardinal process. 
5. Cross-section of the rostral portion of another specimen, to show dental 
supports in pedicle valve. 
6. Longitudinal section of another specimen, to show length of cardinal process. 
This genus differs from Triplecia in having the surface cov- 
ered with plications or stride, which increase by interpolation 
and bifurcation; in the large, triangular, slightly concave car- 
dinal area of the pedicle valve; in the broader, usually fiat 
deltidium; in the shorter cardinal process; and in the longer 
beak of the pedicle valve. 
Type : Oxoplecia calhouni sp. nov.
