218 MOLLUSCA. 
Dr. Pfeiffer received his specimen of this species from Dr. von der Busch in 
Bremen, with the statement that it came from Costa Rica. The Berlin Museum 
received examples of it many years ago from Mr. Carmiol, who travelled in Costa 
Rica, but he could not give the locality more definitely. Dr. Gabb has also reported 
it from the same country, without nearer indication.

Differs from O. costaricensis in the peristome not being expanded and in the more 
numerous linear brownish stripes. I have not seen a specimen of it.
