New AuRicuLiD.« which inhabit Jamaica. By C. B. Adams. Oct. 1849. 



Melampus coronatus. Shell obconic ; reddish purple ; with 

 several spiral punctate striaj and distant transverse striae, and a de- 

 ciduous epidermis, which is produced into a small spine at each of 

 the principal transverse striae on the spire ; spire rather short, with 

 outlines slightly concave ; apex very acute ; whorls about seven, 

 slightly shouldered, with a moderately impressed suture ,• aperture 

 with a large solid spiral prominent callus or tooth on the columella. 

 The two specimens before me may be young shells, but probably 

 belong to a new species. 



Length .11 inch; breadth .07 inch. 



Pedipes ovalis may be a variety of P. quadridcns Pfr. ; but 



when full grown it is oval ; the spiral ribs on the last whorl are 



broad and approximate, and on the whole shell they are smootli, 



without the irregular microscopic granulations of P. quadridens:
