 M. smithfieldensis.

Malleria smithfiefdensis, n. sp„, Plate 3, Fig. 17 



Shell very small, naticoid ; spire prominent and elevated ; 

 suture distinct and deep ; whorls about 3, solid, rounded and 

 smooth above with spirals on the base ; last whorl somewhat 

 descending ; upper surface smooth, with indistinct lines of 

 growth ; base with a deep umbilicus, not angulated above and 

 with strong spirals, the 1st 3 (in and around the umbilicus) e- 

 qual and separated by relatively wide interspaces, the others al- 

 ternate in strength and rapidly become obsolete and dissapear 

 towards the periphery ; the 1st spiral is within the umbilicus, 

 the 2nd and 3d, may be considered as outside ; the specimen shows 

 4 other alternating spirals and a few, very obscure ones nearer 

 the periphery ; mouth rounded, somewhat angulated above and 

 only slightly attached, internally showing the operculate shelf. 

 Greater diameter 1.00, height .75 mm. 



A series of specimens show some variation in the strength 

 and persistence of the basal spirals. Usually, they are as de- 

 scribed above, but occasionally the spirals may continue onto the 

 periphery and also on the upper surface. The species lacks the 

 radial, incised, basal lines of M. harrisi.
