P ‘ 2 
~ Genus CanceLLarra.— Lamarck. 
C. pulcherrima. Pl. 1, fig. 15. 
C. testa sub-fusiformi, cancellata, striis longitudinalibus equalié 
bus transversis, lineis crebrissimis parvis, transversis, sub-crassa, 
umbilicata; spira obtusa,.mammillaté; anfractibus senis, con- 
vexis, superné angulatis ; suturis impressis ; umbilico parvo; col- 
umella duabis plicis; apertura sub-elliptica ; canale brevissimo ; 
labro crassissimo. 
Shell sub-fusiform, cancellate, with the longitudinal striee 
equal to the transverse ones, with small transverse lines very near 
each other, somewhat thick, umbilicate ; spire obtuse, mammil- 
late; whorls six, convex, angular above ; sutures impressed ; um- 
bilicus small; columella with two folds; mouth sub-elliptical ; 
canal very short ; outer lip very thick. 
Length -4. Breadth of an inch. . 
Remarks.—This elegant little species is remarkable for the 
raised points at the intersections ‘of the longitudinal and trans- 
verse stri, which render it muricated, and give it a beautiful ap- 
pearance. It resembles considerably C. mudtiplicata, Lea, but 
may easily be distinguished from that species, by its being cancel- 
ate and muricate, but I cannot determine whether the shape of 
the mouth differs, as the outer lip of my only specimen is very 
much fractured. 'The mouth is just half as long as the shell. 
Genus Trrron.— Lamarck. 
T. pyramidatum. PI. 1, fig. 16. 
T.. testa turrita, crassa, polita, transverse striata; spira acuta ; 
anfractibus nonis, convexis ; suturis impressis; columella levi ; 
apertura sub-elliptica, sub-effusa. 
Shell turrited, thick, polished, transversely striate ; spire acute ; 
Whorls nine, convex; sutures impressed; columella smooth; 
mouth sub-elliptical, somewhat effuse. 
Length Breadth °3 of an inch. 
Remarks.—It is with some hesitation that I have placed this 
Shell in the genus Triton, to which, however, it appears to be- 
long, from its irregular varices, of which some of the whorls have 
but one, and some two. Tt appears to have had a rostrum at the 
of the mouth, but as I have only a single specimen, which 
has it broken, I cannot determine its size. It is remarkable as
