Turbo confragosus, GouLp; Proceed. Boston Soc. Nat. Hist., 111. 89. 
March 1849. Expedition Shells, 54. 
Anima colourless. Head broad, mouth inferior, tentacles long and 
subulate, eyes on short basal pedicles; foot oblong oval, centrally fur- 
rowed ; winglike appendages of the mantle anteriorly, from the edge 
of which, midway, arise two short, approximate cirrhi each side; a 
spot at the inner base of each tentacle, and a submarginal band sur- 
rounding the head and foot composed of short, blue-black lines; ten- 
tacles annulated with the same. 
Suet low conical, somewhat turreted, solid, pale cinereous, surface 
rugose, the wrinkles small, rounded, uregular, oblique, slightly squa- 
mous here and there; whorls about six, somewhat shouldered above, 
declivous at the upper part, and having two angles towards the base, 
on which about every third rib is prolonged into a folded spine, quite 
small on the upper ridge, but distinct on the lower one, which consti- 
tutes the periphery of the base, and thus becomes stellate ; suture cal-. 
lous; base plane, encircled with about eight distinct, approximate, 
squamose ridges, generally alternately Jarger and smaller; aperture 
circular, lip sharp, very oblique ; columella short, rounded, at the base 
of which is a distinct white tooth, lying obliquely across it; interior 
silvery. 
Diameter an inch and an eighth; axis seven-eighths of an inch. 
Found at Dean’s Island, Paumotu Group. Couthouy. 
This species has the low conical form and bony aspect of the stel- 
late species found in the West Indies. I know of no other similar one 
from the Pacific. Its wrinkled surface, polygonal whorls, and the 
squamous basal ridges, mark it.
