oblique, rounded, thin-edged, hardly interrupted by the body-whorl or umbili- 

 cal carina. Alt. of two specimens, A and B, A 7, B 5.5 ; max. diam. A 8.5, B 

 7.0 mm. 



This species has been generally confounded with vS. elegans, which is a 

 less elevated shell with a scalar umbilicus and generally with several elevated, 

 rather distant spirals and more prominent sculpture.

Older Miocene of the Chipola River, one mile below Bailey's Ferry, 

 Calhoun Co., Florida, Burns. 



Shell small, conical, with six whorls; nucleus small, inflated, smooth; 

 next two whorls reticulated by about four spiral and numerous transverse 

 elevated threads ; subsequent whorls with an elevated thread a little in advance 

 of the suture and two at the periphery, the posterior of these the stronger, 

 beside several rather obscure smaller ones on the base, in addition to which 

 the whole surface is minutely spirally striated; the transverse sculpture con- 

 sists of numerous minute, narrow riblets, with wider interspaces, directed in 

 harmony with the incremental lines, most elevated just in front of the suture, 

 and by which the posterior primary spiral rib is crenulated, beyond which 

 the riblets are not distinguishable from the lines of growth ; the whorl between 

 the suture and the first primary spiral is flattened ; in front of the primary it 

 is rounded, the base is swollen; the umbilicus is large and funicular; the 

 umbilical carina strong and crenulated, separated from the base by a well- 

 defined groove; the umbilical walls are coarsely sculptured by two or three 

 strong and several feebler crenulated spirals separated by excavated sulci; the 

 aperture is rounded, with a thin edge, crenulated by the exterior sculpture ; 

 color-markings, in the shape of rather distant, small purplish spots, still appear 

 on the primary spirals. Alt. of shell 5.6; max. diam. 6.0 mm. 



A single specimen of this pretty and very distinct species was obtained 

 by Mr. Burns.

The characters of this very pretty little shell are well exhibited by the 

 figures given. It measures 5.8 mm. wide and 5.5 mm. high when adult. The
