It is indeed a macandrewii.

It looks an Erosaria spurca! Yes, I mean the Mediterranean commonest
cowry. Coming from Eilat (Red Sea) it would be one of the so-called
anti-lessepsian migrant. Since I tend to be very reluctant in accepting
antilessepsians, I would consider the possibility of fortuitous
record. I must anyway admit that accidental import of a shell of
cowry from the Mediterranean to the Red Sea would be strange .....
I do not confirm Marco's
identification at the moment, however, I like to pay attention to
the fact that single specimens of Erosaria spurca has been found
3-4 times at various localities in the Red Sea. Probably they fall
within the category of hitchhikers not in that of Anti-Lessepsian
It seems to be a Erosaria
marginalis melocellata Lorenz & Wiese, 1990. I have some specimen
from Zanzibar Isl. (little bit different from somalian specimen)
that looks like the figured shell. I don't know if the distribution
of Erosaria marginalis melocellata reach so far north. I will be
pleased to have some information from Mr. Mienis.
does not occur in the Red Sea!
shell is really looks like Erosaria macandrewi form confused (confused
dorsal pattern), but there are several questions we have to know
before drawing a conclusion . The base of the shell in question
is white although it is never white in E. macandrewi. A possible
reason for this is too much light during making a picture. Could
you please let me know a color of the base of this specimen?
the base is creamy
white . What about the teeth ? They seem to differ from those of
standard macandrewis ... I am not sure that the shell was live taken
or not for with a magnifier one can see tiny scratches on the dorsum
here and there .
it may be a dead found,
not completely adult shell of E. macandrewi but sometimes (very
rarely) dark colored lines near the labial teeth are absent in adult
shells too. E. macandrewi is a very variable species.
I agree with
P. F. From my experience in Somalian shells, after to have see thousands
of cypraea for me is one erosaria marginalis dead taken, this explains
the atypical distribution
The dentition is close
to spurca (it can't be macandrewi with such a base) but, dorsum
coloration is undoubtedly close to macandrewi. My answer would be:
hybrid : SPURCA X MACANDREWI.
occur (very rarely but it occurs) , particularly, for cowries of
a same subgenus. As spurca and macandrewi are EROSARIAs...
