Tut CassIs-SHAPED TURBINELLA. Shell ovate, ven- 
tricose at the upper part, depressly angulated, spire 
very short, base attenuated; whorls flattened above, 
encircled throughout with rounded many-scaled ridges, 
interstices excavated, also scaled, scales tubercular 
and compressed at the angle, somewhat prominent 
towards the base; columella rather concave, three- 
plaited, aperture elongated, expanded; whitish, 
stained and banded with light rusty brown, columella 
and interior of the aperture pink and brown. 
Hab. West Indies. Bahia; Kiener. 
Approaching nearest in form to the following species, 
T. rhinoceros, but easily distinguished by the beautiful 
succession of squamate ridges with which it is encircled 
throughout.

THE RHINOCEROS TURBINELLA. Shell ovate, turbinated, 
thick, ventricose round the upper part, attenuated at 
the base, spire short, acute; whorls transversely 
striated, armed round the upper part with rather 
distant large swollen tubercles, and two rows of squa- 
mate tubercles near the base ; columella three-plaited, 
aperture elongated, somewhat expanded; whitish, 
variegated with chesnut-brown, columella brown, 
plaits white.

Characterized by its large swollen rather distant 
tubercles. 
Species 34. (Fig. a and 6. Mus. Cuming.) 
TURBINELLA CHsTUS. Turb. testd ovato-turbinatd, crassa, 
ponderosa, spird brevi, acute acuminatd, anfractibus 
longitudinaliter subplicatis, transversim sulcatis, su- 
perné angulatis, ad angulum fortiter tuberculatis, 
tuberculis rudis, obtusis, tuberculorum seriebus duabus

mide crassa fibrosa induta. 
THE BOXING-CLUB TURBINELLA. Shell ovately turbina- 
ted, thick, ponderous, spire short, sharply acuminated, 
whorls longitudinally slightly plicated, transversely 
grooved, angulated round the upper part, strongly 
tuberculated at the angle, tubercles rude, obtuse, 
with two rows of tubercles near the base; columella 
four-plaited; white, covered with a thick fibrous 
epidermis.

The adult example of this species has so much the 
appearance of a monstrously developed specimen of the 
T. muricata, that I have considered it necessary to figure 
the young in both instances to exhibit the difference, which 
though slight appears constant. The furrows are broader 
in this species, the tubercles larger and more swollen, 
whilst there is an important variation in the plaits of the 
columella ;—in the 7. cestus they consist of four nearly 
equal plaits, in the 7. muricata there are five, three large, 
and two intermediate small; and this distinction occurs 
in each species throughout all stages of growth.
