﻿127 Florida Oligockne Shells 



the last third of the body whorl, their termination being marked 

 by a more pronounced varix-like riblet ; space between this ter- 

 minal rib and the outer lip showiug strong, transverse lines of 

 growth. Ribs on the body whorl seven. Notch U-shaped, dis- 

 tinct ; outer lip thickened near the edge ; pillar with a moderate 

 callus. Length of shell 9.5 ; greatest width 3.75 mm. 



Chipola marls, Bailey's Ferry, Florida.

Drillia Meimieri, n. s. 

 PI. II, fig. 5. 



Shell resembling D. Grabaui but much larger and stronger. 

 Whorls without the nucleus, which is eroded in the single speci- 

 men found, eight ; spiral sculpture of sub-equal, shallow, narrow 

 grooves extending from the notch to the base of the whorls ; sub- 

 sutural band very slightly nodular ; transverse sculpture of 

 fairly distinct ribs (thirteen on the last whorl) which become 

 weaker and tend to fade out on the last whorl. The ribs extend 

 from the notch to the succeeding suture and to about the center 

 of the body-whorl. Notch distinct, broadly U-shaped ; canal 

 short, wide ; aperture rather narrow ; outer lip not lirate within ; 

 pillar with a rather thick callus. Length of shell 41 ; of aperture 

 18 ; greatest width 21 mm.

Drillia nemoralis, n. s. 

 PI. II, fig. 6 

 Shell small, rather solid, about eight-whorled, nuclear whorls 

 eroded in the specimen found ; spiral sculpture of raised threads 

 covering the whorls except on the sub-sutural grooves, which are 

 smooth ; transverse sculpture of riblets (seven on the body- 

 whorl), which are strongest at the periphery of the volutions and 

 do not cross the subsutural grooves ; aperture oval-elliptical ; 

 notch slight and inconspicuous ; pillar with a moderate callus.
