scend, anil at tliis part with more of colour ; hut they hare 
no middle line; and in the larger specimen their form i* 
much less regular than in the smaller. From the line of 
separation of the whorls run a considerable number of brown 
lines, encircling the convexity of the whorls, and uniting ths 
longitudinal lines of arrowy marks, but not actually breaking 
in on their continuity. The comparative number of these 
encircling lines, as well as their regularity, is much greater 
in the larger specimen. 
A close inspection of these shells in comparison with a 
small parcel of Naticai , of about the size of small peas, and 
which without enquiry I had believed to be all of the more 
common species, lias impressed me with the belief that the 
N. intricata is not so rare as has been supposed ; for I found 
several among them distinguished by the regular lines ot 
arrow shaped marks, and thereby easily separated from 
others of paler cast, and with only one line, of obscure linear 
marks near the border of the whorl. On further examination 
I find also on these prettily marked specimens that the spir° 
is less elevated, and possesses the general form already 
described as belonging to N. intricata. But. it is remarkable 
that in the umbilicus and band all these specimens are alike, 
and resemble N. g laucina: a circumstance which does not 
excite in my mind any doubt of their being of different 
species, and that those having lines of arrow shaped marks 
are a young state of N. intricata ; for 1 believe that th* 
observation of Professor Forbes may be depended on : that 
colour in the Naiicae is distinctive of species, but at the sain* 
time it tends to show that in their younger condition they 
resemble each other in that which subsequently constitutes 
their most important difference. In their youthful condition, 
then, the marking of the body-whorl, and the depressed and 
irregular form ot the spire must be regarded as the chief 
distinctions ; to which in the adult state must be added lb 0 
situation and structure of the band and the umbilicus inter- 
secting it; but bow far this shell is thus separated from the 
ioreign species ot Nalicaa described by authors, I have not 
the means of knowing.

This species is a common native of the Mediterranean, and 
the few dead specimens which had been found on the Cornish 
shores were judged to have been thrown where they where 
they were discovered, by some accident. But in the month 
of August 1844, a small specimen with the animal alive, was 
taken in a trawl in Mount’s bay ; and it is now preserved 1° 
the collection of Mr. R. Q. Couch at Penzance.
