San Diego. Catalina Island, San Nicolas Island, California. 



The specimen Ggured is from Catalina Island, California. I 

 am not positive that it is correctly referred to H. kelle.tti. The 

 umbilicus is entirely closed in mature specimens. There are 

 traces on different parts of each shell of three different series of 

 sculpturing ; the wrinkles of growth, revolving impressed lines, 

 and a series of minute granulations running obliquely, sometimes 

 almost perpendicularly, to the incremental wrinkles. 



Forbes' original figure of H. kelletti is copied in the fourth 

 volume of the Terrestrial Mollusks.
