Under this name I would place a shell found common at Orange 
Harbour, in company with P. deaurata, and which, indeed, from the 
shell alone, might be ranked as one of the forms of that variable 
species. But Mr. Couthouy says, “There are also many varieties of 
this shell as to configuration, coste, &c., but in no case does the 
animal approach that of P. deaurata. The foot is more elongated or 
oval, and lighter coloured. The branchiz surround the whole body ; 
the cirrhi on the mantle are longer and more slender, and the head 
and tentacles rather shorter. The latter have also a dark purple or 
brown stripe on their upper side. The colour of the entire animal is 
olive-green, except the sides of the foot and muscle of attachment, 
which are shining white. Soup was often made of this and P. deau- 
rata, which was much relished.” 
The shell above referred to is probably the oval, elongated shell, 
with an anterior apex; the exterior is marked by flammules, but not 
the interior, except by transmitted light; the spatula at the fundus 
is dark gilded-brown. It might be taken for P. flammea, Gmelin, a 
shell which I suppose to be a New Zealand species, of a more de- 
pressed form, thinner, the ribs less numerous and less developed; the 
apex more obtuse and more central, the lines of profile much arcuated ; 
the aperture more ovate; the interior spoon-shaped, without any de- 
pression answering to the apex; the central spatula leaden-coloured, 
and the surface coloured by dark, reticulating radiations. ‘These are 
characters which best agree with Deshayes’ amplified description, as 
well as with his habitat; still it may be a question which is the real 
P. flammea.
