 at the depth of six to ten fathoms) ; Cuming. 

 Distinguished by its nodulous structure, which is a 



character of rare occurrence in this genus.

Hab. ? 



This remarkable shell has beeu thought to Ijelong to a 



Fennetiis, but its growth is perfectly regular.

Cuming's Turritella. Shell rather lanceolately pyra- 

 midal, rather thick, whorls about twenty in number, 

 flatly slanting, swollen and obtusely angled round the 

 lower part, spirally five-ridged, ridges naiTOw, rather 

 shai-p, regular; brownish white, obliquely clouded 

 thi'oughout with purple-brown streaks and blotches. 

 Hab. Panama (in mud at depths from eleven to sixteen 

 fathoms) ; Cuming. Conchagua ; Belcher. 

 Several specimens of this fine species, which I have the 

 pleasure to dedicate to Mi-. Cuming, were dredgetl by him 

 at Panama. It was also collected by Sir E. Belcher at 

 Conchagua dming the voyage of the Sulphur. Each 

 whorl is swollen outwardly at the base so as to form an 

 obtuse angle, and the five ridges which encircle them are 

 continued without change throughout the spire.

The COLUMNAR TuRRiTELLA. Shell very sharply lan- 

 ceolately tun-eted, sharply angled at the base, whorls 

 about thirty in number, the fii'st two-keeled, keels 

 approximated, the rest rather flattened, ten-ridged, 

 ridges obsoletely granulated, sutures excavated; 

 greyish-white, clouded with purple-fawu obliquely

This species has the largest number of whorls, and is the 



most elongated form of the geuus.
