06 THE NAUTILUS. 



Long ]\It., tliousands of dead specimens of the genera Helix, Cylin- 

 clrella, Cyclotus, Choanopoma, etc. were observed, but only a few liv- 

 ing Lueidella aureola Fer., were found. At Rockfort Orthalicus 

 uiidatus Beck were seen sestivating and a supply obtained, each 

 epiphragm being carefully preserved. 



At Pensacola two cemeteries were visited. In the older one Helix 

 (^Dcedalochila) pustula Fer., were tolerably abundant, and a few 

 Hyalinia. In the newer one Helix (Mesodoii) jejuna Say, var. Mohi- 

 liana Lea, were seen in great numbers. As the soil is very sandy 

 and as it had rained the night before, each shell was covered with a 

 small heap of sand. They were found on the head and foot stones 

 aud on posts. They had crawled up from one to two feet from the 

 ground. 



The following are the lists for the regions visited : 



West Indian Islands.

 specimens were found equally abundant at Barbados, St. Kitts and 

 St. Thomas. Is^o marine forms were collected at Kingston, Jamaica.
