The species of this genus are found in Mexico, Hayti, 

 Cuba, and Jamaica. The tip of the spire usually falls off 

 when the animal has added new whorls to the shell, " a wise 

 provision of nature," says Guilding, " since its foot being so 

 short it would not have the power of drawing along so heavy 

 a shell." The single species of Diaphera is from the 

 Philippine Archipelago.
