j[ it’s figure is deprefled and flat3 it’s mouth the moft patent of all the fhells, the 
limpet only excepted: it has a fhort fpiral turn running into the mouth at the head, 
and has no perforations in any part of the furface. 
Authors have confounded this fhell with the Auris mariana, or Haliotis 3 but with 
how much impropriety is evident, from the want of the perforations, which are the 
diftinguifhing character of that genus, and from the difference in the fpiral turn of 
the fhell. 
The animal inhabiting this fhell is a nereis5 and in this alfo it differs from the 
haliotis, that and the patella being inhabited by a limax.
