MONOGRAPH OF THE GENUS STROPHIA, 
HABITS AND DISTRIBUTION. 
In March, 1893, I found the Agava Strophia common throughout 
the sisal fields to the westward of Nassau as far as the fields extend, 
and I traced it for about eight miles westward and about a mile back 
from the coast. The form becomes more typical as it recedes from 
the type location of S. neglecta, and we found some very fine, large 
specimens about a mile south of this point. 
This shell, which has beyond all doubt, been developed into what 
is nearly a well-established species through the clearing of the fields, is 
frequently found clinging to the huge leaves of the sisal plants, but it 
is also fuund on herbage and shrubbery which grows in the fields,
