In the Queensland examples the sulcus of the ventral valve channels the umbo 
up, and gradually broadens out towards the front, which is well sinuated. The 
°*d of the dorsal valve is not high, but narrow and ribless, except at the front sinuated 
niargia^ where it rather projects upward. The hinge line is less than the width of the 
^a-lves, the area of the ventral valve being short and low, whilst the alar angles are 
Jj^unded. Both beaks are fairly prominent, and that of the ventral valve incurved. 
® surface always appears quite smooth.

Only one specimen. It is quite decorticated, much smaller than the preceding, with 
eep well-pronounced sulcus in the ventral valve extending well up on the beak, and 
bonded by strong ridge-like margins. In the dorsal valve there is a corresponding 
iu^l'*^^ luld although not relatively so prominent as the sulcus. The hinge line was less 
I ®^otli than the width of the shell. It appears to resemble some of the Martinia

and the present species.
