Hab. N. and E. Guatemata: Province of Peten?4, in rocky localities (Morelet 1) ; 
Livingston, Bay of Honduras (Stoll); Vera Paz (Salvin ®). 
Somewhat similar to C. ot¢tonis, Pfr., from Cuba; but of a more oblong form and 
wanting the peculiar extension of the outer peristome on the body of the last whorl, 
which distinguishes the Cuban species. The specific name has reference to the 
radiating dark brown pattern of the peristome. ‘Tristram® also gives Duefias as a 
locality, perhaps in error.
