6. Epidromus texturatus, s'pec. nov. Plate vi., fig. 10. 



Shell ovately-turreted ; whorls nine and a half of regular 

 increase, terminating in a large hemispha3ric apex of two and a 

 half rapidly decreasing whorls, the tip hardly depressed. The 

 first whorl is smooth, the next is ornamented with flexuous 

 radial ribs ; the rest of the wdiorls rounded, but flattened 

 behind, ornamented with revolving threads and curved costula- 

 tions, spinosely granulated at the intersections ; the intercostal 

 spaces closely rugosely striated in the axial direction, and 

 spirally by rounded threads with linear interstices. There are 

 six lirse on the penultimate whorl, none on the posterior slope, 

 which diminish in strength towards the anterior suture ; and 

 40 to 50 costulations on the penultimate w^horl, reduced to 30 

 on the body whorl. 



Varices nine, broad, somewhat depressed. 



Outer lip shortly lirate within ; inner lip narrow, smooth. 



Length, 37 ; breadth, 14 ; length of aperture and canal, 17. 



Localities. — Blue clays, Schnapper Point ; lower beds at 

 Muddy Creek {J. Dennantl). 



The specimen from the latter locality has thicker spiral ribs 

 and larger tubercles, especially those of the posterior rib, 

 which imparts a more quadrate outline ; the costulations on 

 the last whorl are fewer. 



7. Epidromus turritus, spec. nov. Plate iv., fig. 4. 



Shell turriculate, whorls eight, terminating in a blunt apex 

 of two smooth subcylindrical whorls much smaller than the 

 regular whorls ; the third and fourth whorls bicarinate, the 

 rest of the spire whorls angulated and shouldered, and much 

 contracted towards the anterior suture ; body whorl regularly 

 and moderately convex, proportionately narrower than penul- 

 timate whorl, gradually attenuated into a broad, short, reverted 

 beak. Ornamented with narrow, flat, spiral threads (five on 

 the posterior slope of the penultimate whorl, 18 on the anterior 

 portion, two of which, one on the keel, and one nearly medial, 

 are stouter than the rest), crossed by costul^e (about 30 on the 

 penultimate whorl), which are spinulose-granulated at the 

 intersections ; intercostal spaces closely, finely, tranversely 

 striated. 



Varices three, confined to the anterior whorls, inconspicuous, 

 having the form of lamellate imbrications. 



Outer lip with numerous, short, slender ridges within ; inner 

 lip narrowly reflected, smooth. 



Length, 27"5 ; breadth, 9 ; length of aperture and canal, 13. 



Localities. — Lower beds at Muddy Creek (J". Dennant I and 

 J. B. Wilson'.)', blue clays at Schnapper Point (72. T.).
