Plate XIX, figs. 1. la. 
Holotype, a right valve from West Beach, Corio Bay, Reg. No. 13685. 
Description. — Shell subquadrate, somewhat convex at umbo, depressed 
towards anterior margin ; a faint median ridge extends from umbo to post- 
ventral margin. Umbo sub-central, directed anteriorly ; lunule well defined, 
long, not striate ; dorsal margin fairly straight ; anterior margin rounded ; 
posterior obliquely angular; ventral margin strongly arched posteriorly, 
tapering towards anterior end of shell. Surface ornament consists of con- 
centric ridges, somewhat flattened and reflected, interspaces plain ; no radial 
ornament. Inner margin of valve bevelled ; finely crenulated on inner side 
of bevelled edge. 
Dimensions.— Holotype : — Length, 18 mm. ; height, 15 mm. ; depth of 
valve, 4 mm. 
Observations . — This fossil resembles Salaputium communis 
(Tate) =Crassatella communis Tate in shape, but is larger and, 
unlike 5. communis, it has the inner margin crenulated. It also 
bears some resemblance to S. aldingensis (Finlay ) =Crassatella 
corrugata Tate, but the latter has a plain margin and is striate 
between the corrugations. 
Localities. — West Beach, Corio Bay (Type). North bank of Mitchell River 
above bridge 10 miles upstream from Bairnsdale. 
Geological Horizon. — Barwonian (Oligocene or Miocene) .
