The carapace is slightly tumid beneath the posterior half of each pseudorostral 
suture. There is a distinet short median longitudinal carina anteriorly only; it 
ends abruptly at the middle of length of frontal lobe. 
The colour pattern is variable. Some specimens are darkly pigmented, with 
large chromatophores as shown in fig. 17, A; others are grey with few or no darker 
spots. Often, but not always, the anterior portion of the carapace is markedly 
lighter, with conspicuous demarkation.
