VERTICORDIA TASMANICA, Sp. Nov. 



Shell small, white, inflated subrhomboidal ; umbo much 

 incurved ; on its summit a small, smooth, sharply-defined 

 prodissoconch, lunale deeply excavate. Sculpture : The 

 whole surface of the valve is ornamented with very numer- 

 ous radial rows of minute granules, giving the shell a 

 sandy appeal anc& ; at about every five rows is a narrow 

 groove or space. Interior nacreous ; under the umbo in 

 the right valve is a massive cardinal, and a small lateral 

 apparently under both dorsal margins. 



Height 4. Width 4.5 mill. 



Type, from 100 fathoms, seven miles east of Cape Pillar, 

 with several others; also from off Schouten Id.) 40 and 80 

 fathoms. Only a few examples have been taken — all single 

 valves. This species has considerable general resemblance 

 to V. torrida, Hedley, but the anterior dorsal slope is much 

 lees steep. The sculpture is without the ribs, and it is 

 larger.
