Capiluna RuppeUi, var. Barroni, var. nov. (PI. XXII, Figs. 1-4.) 



The above varietal designation is applied to a number of forms 

 which are nearly circular in outline, besides being more conical 

 and elevated than the typical species. Sculpture characters, 

 however, are identical ; the numerous raised beaded ribs and riblets 

 exhibiting the usual beautiful structure of this shell. The oblong 

 perforation is also normal, and shows a slight enlargement at the- 

 posterior end. The basal margin is denticulated and laterally 

 excavated. Size variable. Dimensions of largest specimen : height, 

 15 mm.; length and width, 18 mm. 



This variety is represented by about a dozen specimens which 

 were found associated with the true C. Biippelli. It is to be seen 

 in an unnamed condition in the Eecent shell section of the British 

 Museum, labelled as from the Eed Sea, although the specimens have 

 all the appearance of coming from the beach deposits of that area. 

 Probably the form is extinct.
