broad. Plastron intermediate, as to size and shape, between C. 
nove-qunee and C. oblonga, strongly angulated laterally ; lobes

its length; the longest plastral shields are the pectorals; intergular 
once and a half as long as the suture between the pectorals ; suture 
between the anals shorter than that between the femorals. A series 
of seven or eight transverse lamelle on the upper surface of the

pectorals ; suture between the anals as long as, or shorter than, 
that between the femorals. A series of six or seven transverse
