Turboyiilla (Mormula) mitchelliana , .n. sp. 

 Plate III, fig. 3 



Shell medium ; spire smooth, embryonic whorls bent to one 

 side and partially immersed ; whorls nine T surface smooth, shell 

 shouldered at suture and compressed below same. Inner lip 

 reflected and bearing" one fold ;' outer lip sharp, striated with- 

 in. The body- whorl is large ; looking down on the shell from 

 the a^ex the suture seems to cut under the whorls. 



Height 7.5 ; maximum diameter of body-whorl 2.5 mm. 



Six miles east of Thomasville, Ala. Woods Bluff beds. 



This species is about the size and shape as Turbonilla an- 

 ita Aldr. but has no spiral lines, also carries a prominent fold 

 on the columella. Dr. P. Bartsch has kindly determined its 

 generic position. ■ 



Eulima extremis, n. sp. 



Plate III, fig. 4 



Shell polished ; whorls nine or ten ; suture very shallow 

 showing indistinctly ; aperture elongate ; outer lip slightly sin- 

 uous ; inner lip reflected over the lower part of the pillar. 



Length of longest specimen 7 mm. 



Claiborne Sand bed on Tombigbee River about one mile 

 above St. Stephens, Ala. Also at Claiborne. 



This species is longer than E. adculata Lea, and more slen- 

 der, that species averaging about eight whorls, while this has 

 nine to ten. All specimens of this species show a broad con- 

 striction below the suture, and even retain some traces of a col- 

 or band there. The suture in Lea's species is plainly marked. 

 Eulima lugubris Lea has a more circular aperture, a more thick- 

 ened and reflected columellar callus and is broader.
