Voluta, sp., PI. 4- fi^- 3- 



This fragmentary specimen was found at Yellow bluff. It is 

 the only Voluta we have presenting the plication features as 

 shown in the figure. The costation is continued to a slight 

 extent even on the body whorl. It is just possible however 

 that this is but an aberrant form of V. neiL'conibiana, though it 

 is more probably an ancestral type of Lapparia paclilis.

Wtiitfield" s original description. — "Shell strong and robust ; 

 volutions six or more, moderately convex in the younger stages 

 of growth, becoming more ventricose, and finally angular in Lhe 

 upper part of the body whorl ; suture distin(5l ; aperture about 

 four times as long as wide, angular above, and deeply notched 

 at the base, forming more than one-half the length of the shell ; 

 columellar folds four, very strong, the upper one transverse, the 

 lower ones more oblique ; outer lip thick and smooth ; surface 

 marked only by distindl lines of growth. 



'"Dimensions. — Length 3^ inches, diameter \'Y% inches. 

 ''Locality. — Six miles above Claiborne, Alabama." 

 By this Whitfield doubtless meant Bell's landing. Aldrich 

 states in 1887 that it is found only at this locality, while in 18S6 

 he gives Nanafalia as well. It is not rare at Yellow bluff. 



Type. — Hall's colle(5lion.
