 S. ANTILLARUM Shuttleworth. 



The shell, the only Scutellina I have seen from the Gulf or 

 Antilles I suppose to be Shuttle worth's species. It is a small thin 

 shell, about 8 by 6 mm. at the base, and 3'0 mm. high. The apex 

 is situated in the posterior fourth of the length, and has a minute 

 dextral half-immersed spiral nucleus, whose extent is marked by a 

 slight contraction where the conical shell begins. The anterior 

 slope is prettily and evenly arched, the posterior slope steep and 

 concave beneath the apex. The surface is of a brownish straw- 

 color, the interior subtranslucent white of brilliant polish but not 

 nacreous. The sculpture is of very numerous, fine, radiating raised 

 lines, with minute spines or vaulted scales closely set upon them, 

 giving a rasp-like surface ; there are no regular concentric lines, but 

 only occasional lines of growth. 



I have described it thus fully as I suspect Shuttleworth's name is 

 a mere catalogue name which has never been validated by a de- 

 scription or figure. At least, after very full search I have failed to 

 find any description or reference to a description. It is not the 

 Patella (Acmsea) antillarum of Sowerby and Philippi.
