A single specimen of this shell has been kindly lent to us by Mr. 

 Millard, of Bristol, who is not acquainted with its locality : we 

 have seen another specimen in Mr. De Ferussac's collection, which 

 was brought from South America by M. De Humboldt. 



SlioU suborbicular, rather discoid, with a very short spire; vo- 

 lutions four, the upper ones nearly covered, the last very large, 

 rounded above and its lower edge rather keeled, with a very 

 rounded keel ; umbilicus spreading, its columellar callus spiral, 

 flattened at its lower end : aperture large, interrupted at its upper 

 part by the last volution, obliquely produced at the lower part.

 septenis, coiivexiusculis, laevissimis, olivaceis, longitudinaliter in-

 La Guayra. Two specimens have been presenttd to the British 

 Muscuuij by Dr. N. 11. Oxcytie.
