SOME NEW OR UNFIGURED AUSTRALIAN SHELLS-- HEDLEY. 27 



Habitat. — With Periploma micans and other shells, this was 

 labelled in Mr. J. Brazier's writing "seventy-five fathoms, five 

 miles east of Sydney Heads." 



Fig. 8. 



Three separate valves represent the species. 



The novelty seems to resemble Sarepta speciosa, A. Adams," 

 more than S. abyssicola, Smith.* Neither illustration show the 

 hinge structure clearly enough to enable me to draw a detailed 

 comparison.
