Exilia waringi, new species 

 Plate 9, figure 3 



Shell elongate- fusiform ; number of whorls unknown ; penul- 

 timate whorl marked by a concave surface just above middle; 

 lower half of whorl nearly flat and parallel to the axis ; decora- 

 tion of lower half of whorl consisting of five closely spaced 

 spiral lines crossed by about twenty axial, sinuous, ribs which 

 become obsolescent near base of whorl; upper half of whorl 

 decorated by three spiral lines with alternating threads crossed 

 by strong axial ribs ; body-whorl with similar decoration ; aper- 

 ture elongate-oval; outer lip simple; inner lip marked by five 

 or six very faint lirations ( ?). 



This species resembles Cordiera microptygma Gabb but the 

 axial ribs are different in number and the form of whorl is not 

 convex. The markings on the inner lip of E. waringi are 

 probably spiral lines only and not lirations characteristic of 

 the genus Cordiera. 



Dimensions: — Length of broken type. 12 mm.; width of 

 body-whorl, 4 mm.

 bank of Live Oak Creek about three-fourths of a mile from its
