eluding tlie mamillate apex of two subglobose wliorls ; earlier 

 ones bicarinated, stoutly costated, and latticed by spiral lirae, 

 and frilled lamella? of growth. Anterior whorls bisected by a 

 strong keel raised into wide cuneate compressed serrations, 

 almost tabulated above, conically contracted in front with a 

 strong spiral thread in the middle line ; there are about nine 

 unequal lir?e on the posterior slope of the penultimate whorl, 

 and an equal number in front of the keel. Last whorl a little 

 ventricose in the middle line, rounded at the base, and con- 

 tracted into a long, nearly straight, open canal ; there are 

 eight rounded plications on the whorl, vanishing on the base ; 

 anterior portion of whorl with raised angular encircling lirae, 

 with alternating slender and stouter threads in the interspaces; 

 whole surface crossed by thin continuous lamellae, which pro- 

 ject into vaulted scales on the encircling keels and lirae ; canal 

 ornamented as the base, but the vaulted scales on the stouter 

 ridges projecting into small sharp points. 



Aperture angularly rounded ; outer lip thin, lirate within, 

 continuous with the inner lip which is continued as a sharp, 

 thin, elevated lamina to the extremity of the canal. 



Length, 82 ; breadth, 24 ; aperture, height, 16 ; width, 11 ; 

 length of canal, 35.

 Muddy Creek ; gastropod-bed of the Eiver Murray Cliffs, near 

 Morgan ; and in a well sinking 24 miles north of Morgan. 



Yar., pi. vii., fig. 6, with a longer straight declining shoulder; 

 plications rounded, uot produced into sharp points, the angula- 

 tion which is less prominent. The figured specimen is an ex- 

 treme form, but it is connected wdth the type by graduating 

 specimens.

Shell narrowly fusiform, terminating in an obtuse apex of 

 two smooth subglobose whorls ; whorls eight (excepting the 

 nuclear ones), convex, angular, spirally lirate, and transversely 

 plicate. The lirae are stout convex equal and equidistant, 

 sometimes with a thread in the interstices, about 10 on the 

 penultimate whorl. Costae broad, rounded, about eight to 10 

 on each of the anterior whorls, but diminish in number up the 

 spire, and scarcely appear in front of the periphery on the last 

 whorl. 



Length, 21 ; breadth, 9 ; length of canal and aperture, 16.
