TEREBRATULA SANGUINEA. 
I’, testa sanguinea, subtillissime et creberrime im- 
presso-punctata, longitudinaliter costata, costis sim- 
plicibus; antice uniundalata. 
Habitat in Nova Zelandia. 
BLOOD-RED 'TEREBRATULA. 
Shell blood-red, very finely and very thickly covered by 
impressed dots, longitudinally ribbed, ribs simple ; anterior 
margin with one undulation. 
On either side of the hinge of the smaller valve is a bifid 
process, and another towards the centre of the same valve, 
as shewn in one of the lower figures. 
It seems to be a very rare species, a few specimeus only 
having been received from New Zealand.
