This Asiatic species very closely resembles the American just de- 
scribed, and furnishes another of those instances of affinity, whilst 
still retaining unquestionable distinctness, which occur so frequently 
in the shells of the tropics of the two hemispheres ; and thus whilst 
both are enriched by similar forms, these present themselves under 
slight but constant differences.
