D'Orbiguy's representation appears correct ; but the last sentence 

 of the diagnosis is perhaps taken from another associated species, 

 very likely V. varians, D'Orb., which is always "contourne oblique- 

 ment en spirale," as stated in the description of V. irregularis. I 

 have seen both species together in one group, but the former species 

 very sparingly. According to D'Orbigny, it is found at Cuba and 

 Martinique, " sur les rochers, dans les plaques d'eau, on elle a ete re- 

 cueillee par M. Cande."
