34 TRANSACTIONS OF THE WAGNER FREE 



four (on the last whorl twelve) strong, even spiral cords with hardly wider in- 

 terspaces, and five or six more closely crowded on the canal ; the fasciole 

 shows faint spiral threading of a finer kind on its surface, which is more distinct 

 on the earlier whorls ; transverse sculpture of (on the last whorl about twelve) 

 rounded ribs, which do not quite reach the suture and are obsolete on the 

 canal ; the spirals cross these without nodulation ; lines of growth faint ; 

 terminal varix stout ; notch shallow, rounded ; aperture rather wide and short, 

 with a moderate callus near the notch and on the pillar and a slightly recurved 

 wide and short canal. Max. Ion. of shell lo.o ; max. lat. 4.0 mm. 



The most notable features of this little shell are the uniformity of its sculp- 

 ture and its short and chunky form. 



Drillia podagrina n. s. 

 Plate 2, figure 9. 



Rare in the Caloosahatchie beds. 



Shell elongated, acute, sharply sculptured, with a very small, smooth 

 nucleus; spiral sculpture on the later whorls of (between the sutures three, on 

 the last whorl eight or nine) rather fine, elevated, clean-cut even threads, not 

 enlarged where they pass over the ribs ; there are also a few close threads on 

 the canal and one in front of 'the suture, beside a uniform, extremely fine spiral 

 striation, only visible with a lens, which covers the whole shell ; transverse 

 sculpture of (on the last whorl ten) rounded ribs, strongest just in front of the 

 fasciole, where they shoulder the whorl and extend forward to the canal ; 

 fasciole rather wide, well excavated and somewhat undulated by the ribs ; 

 terminal varix not very marked ; notch deep, rather wide ; aperture moderate, 

 with a well-marked callus on the pillar ; canal short, rather strongly recurved, 

 which, with a sort of constriction behind the canal, gives the siphonal fasciole 

 great prominence, while there is a shallow chink behind the callus of the pillar. 

 Max. Ion. of shell 14.0; max. lat. 5.3 mm. 



This is an elegantly sculptured little species, not very close to any of the 

 preceding. 



Drillia piscator n. s. 



Plate 2, figure 10. , 



Rare in the Caloosahatchie beds. 



Shell small, slender, eight-whorled ; nucleus at first rather large and 

 smooth, later spirally grooved ; later whorls with (on the last whorl seven) 

 rather distinct, flattened, primary spiral threads, three between the sutures, 

 beside two finer ones on the fasciole and several crowded, rounded threads on 

 the canal ; a very strong, rather angular spiral runs in front of the suture, 

 which is otherwise hardly noticeable; transverse sculpture of (on the last 

 whorl about seventeen) faint, narrow riblets, which extend from in front of the 

 fasciole over the periphery and fade away or become duplicated on the base ;
