vescente fusco punctulatd, maculd magna mediand dorsali, maculis- 
que parvis lateribus castaneis; basi subrotundatd, pallescente; aper- 
turd angustd, subfleruosd, anticé latiusculd ; columella postice 
subgibbosd ; dentibus prominulis albidis interstitiis aurantiacis ; 
extremitatibus prominentibus subreflexis ; marginibus prominenti- 
bus subangulatis ; spird profundé umbilicatd. 
Shell oblong-ovate, gradually attenuating towards the anterior 
end, quite smooth; of a very light fawn or light flesh-colour, dotted 
distinctly and irregularly with small chestnut-brown spots, with much 
larger ones on both margins, and a remarkably large spot of the same 
colour about the centre of the dorsum: base rather round, of a very 
light reddish yellow colour: aperture rather narrow, slightly flex- 
uous, somewhat wider towards the anterior extremity: columella 
rather gibbous at the posterior half of the shell ; no columellar groove : 
teeth rather bold, whiter than the base, even, excepting those at the 
anterior end of the columella, where they are larger : all terminate ex- 
ternally on the columella in an even line at the edge of the aperture, 
and within, also in an even line, on the columella, except two or 
three at the anterior end, which advance a little more inwards; those 
on the lip are even, and extend a little over it, outwards ; in number 
they are from sixteen to eighteen on the columellar side, fourteen to 
sixteen on the lip; interstices between the teeth and between the 
extremities more or less of an orange colour: extremities produced, 
the posterior curving towards the columella; the posterior outer beak 
longer than the inner, the anterior very slightly so: margins, the 
outer prominent, angular, more so towards the anterior extremity ; 
the inner exists but on the anterior third of the shell, and is also 
prominent and angular; a groove across the anterior end, from the 
depression formed on either side by the projecting margins, and ter- 
mination of the channel reflecting outwards: spire umbilicated, with 
a notch or groove on the columellar side, from a partial reflection of 
the posterior channel: internal colour light reddish brown. I have 
seen but four examples of this shell, two perfect and two decorti- 
cated. Axis, {ths; diameter, {ths of an inch. 
Hab. Island of Corregidor, Bay of Manilla. Found in coarse sand 
and gravel at seven fathoms. 
In the collection of H. Cuming, Esq. 
Decorticata light brown colour ; large darker spot in the centre of 
the dorsum well-marked ; a brown spot on the outside of each ante- 
rior extremity ; aperture much paler than in the perfect shell. 
I know no species with which this elegant shell could be con- 
founded; the remarkable, large, well-defined spot on the dorsum, 
the orange (more or less) coloration between the teeth and beaks, 
and its gradually attenuating graceful form, distinguish it from all 
others. 
Mr. Cuming, whose valuable labours in the service of natural 
history were rewarded, inter alia, by the discovery of this shell, 
during their four years’ continuance in the Philippine Islands, has 
requested me to name it after an amiuble and liberal collector, Miss 
Saul, and it has afforded me much pleasure to comply with his wish.
