Fam. CORBULID^E.

Inhab. New Zealand, Tauranga, Bay of Plenty. Dr. 

 Dieffenbach. Common. Bidwell. 



Shell oblong, brown, paler rayed, rounded in front, and rather 

 more truncated behind ; periostraca dark brown, much produced. 



This species is very like the one found in the Mediterranean ; 

 but it appears rather shorter, higher, and more ventricose. 



Length 1 T 2 in., height / in. ; periostraca extends beyond the 

 margin of the shell for 3 or 4 lines. 



" The foot is very curious : it is divided at the end and fringed ; 

 when the animal puts it forth, which it can do to full two-thirds of 

 its own length, it opens and turns back like an umbrella or mush- 

 room anchor ; it serves for the purpose of taking a greater hold 

 than would be permitted to the common sort of foot. 



" They live at the verge of the extreme low-water, and below, in 

 greasy mud about 6 inches beneath the surface, and are in all sorts 

 of positions." Bidwell.
