The few specimens of this shell which have been brought in fine 
condition present an appearance cf exquisite finish and great beauty, 
both in sculpture and colouring. They were found in the crevices 
of rocks at low water.

Remarkable for the character of the first valve, which is broadly 
fluted by five radiating ribs. The four or five central valves, in 
several specimens, are nearly covered by a dark purple colour, the 
two last patched with green, and the first nearly white, but subject 
to some variations. Found in coarse sand among small stones at a 
depth of nine fathoms. 
Cuiton Fioccatus. Ch. testd ovali depressd, anticé ungustatd,

terminalibus radiatim sulcatis, valvis medianis utringue unicos- 
tatis, areis centralibus longitudinaliter sulcatis ; areis lateralibus 
granulatis, marginibus serratis ; valvd terminali obtuse elevatd ; 
margine rubro vel fusco, maculis et punctis albis fasciato.

This species is found at Mindinao, under stones at low water, and 
at Calapan on small stones, at a depth of fifteen fathoms. The mar- 
gin is sprinkled with white patches resembling flakes of snow, on a 
reddish brown ground. : 
Cuiton Luzonicus. Ch. testd ovali, angulatd, stramined, viridi

This small and apparently insignificant shell is very sharply 
ribbed in the central areas, and presents a very nicely sculptured 
surface when viewed through a magnifying glass. The specimens 
were taken on dead shells at a depth of fifteen fathoms.
