Solarium Stonemance 

 Plate 23, Figures 4, 5 



Shell conic, depressed, whorls six, handsomely ornamented 

 with oblique, radiating plications often divaricating, cut just 

 ab'ove the suture by a single impressed spiral line, thus forming 

 a revolving row of fine beads beneath which, on the periphery 

 of the last whorl, are three more beaded spirals, progressively 

 finer, all three extending into the aperture; perpihery rounded; 

 under surface sculptured with radiating, divaricating plications 

 similar to those on the upper surface; the shell is so deeply per- 

 forated that one can look through to the apical volution; margin- 

 al teeth small, numerous. Greatest diameter 15, height 9 mm. 

 This species has a slight general resemblance to Conrad's 5". 

 t?~ilineatiim. 



This rare and exquisite shell is named in honor of Dr. Ber- 

 tha Stoneman, Huguenot College, University of the Cape of Good 

 Hope.

 ser., p. 358, pi. 46, fig. 43, 1874 — 1881. (Pliocene Moen shell). 



The thickened outer lip seems so characteristic of Rissoina 

 that the species is here referred to that genus.
