Diagnosis
ReferenceDiagnosis
O. P. Hay 1908Carapace including 8 pairs of costal plates and 1 1 pairs of peripherals, with all or only a part of the peripherals suturally articulated with the costals and the suprapygals. All the costals sending the ends of their ribs into pits of the corresponding peripherals. Five vertebral and 4 pairs of costal scutes. The nuchal scute much wider than long. Plastron relatively small; its connection with the peripherals extensive, reaching from the second to the eighth peripherals, not by close sutures. Bridge relatively narrow. Fontanels in the midline and at the ends of the hyohypoplastral suture. Inframarginal scutes present. Lower jaw with a broad and flat crushing surface; not beakt.
B. Bohlin 1953Carapace including 8 pairs of costal plates and 11 pairs of peripherals, with all or only a part of the peripherals suturally articulated with the costals and the suprapygals. All the costals sending their ribs into pits of the corresponding peripherals. Five vertebral and 4 pairs of costal scutes. The nuchal scute much wider than long. Plastron relatively small; its connection with the peripherals extensive, reaching from the second to the eighth peripherals, not by closed sutures. Bridge relatively narrow. Fontanels in the midline and at the ends of the hyohypoplastral suture. Inframarginal scutes present. Lower jaw with a broad and flat crushing surface; not beaked. (Hay 1908 p. 127).
