The Costa Rica localities given above are for what von Martens 

 calls var. lineolatus, identifying it with the species so named by Con. 

 rad. It is not, however, the true lineolatus, and may be called var. 

 martensianus. Smaller, yellowish, the length of the aperture not 

 exceeding the diameter of the shell. 



Dr. von Martens further remarks: "The stripes of this species 

 are very irregular ; even in the same specimen some are near one 

 another, and others have large intervals between them ; often they 

 are more greyish violet than brown, from being situated in a more 

 internal layer of the shell, and covered by a thin whitish superficial 

 coating. Ordinarily, the stripes break up at the same height at 

 some distance from the umbilicus; in young specimens, as a general 

 rule, they break up at the angularity in the middle of the whorl. 



" The specimens from Costa Rica have generally a thinner and 

 more yellow-colored shell, and the largest which I have seen from
