MONOGRAPH OP THE GENUS STROPHtA. 159 
The size is given as about twenty-three millimeters by ten wide 
and the habitat of the shell described was unknown to Kuster. 
Pfeiffer, however, in Monographia Pleliceorum, Vol. VI, page 291 5 
gives the locality as New Providence, insularum Bahamensium.” In 
Vol. I of the same work, Page 216, he substantially gives a copy of 
Kuster’s description, but in Yoh VI, says nothing further about the 
shell than to give the habitat. Now from these facts we may reason- 
ably conclude that Pfeiffer never saw Kuster' s types, but fitted some 
shell to his description. This shell was possibly my S carlotta, but 
this has nine whirls, not ten, and can scarcely be called “ rosy-white,” 
nor does it resemble Kuster’s figures as cited at the beginning of this 
article. 
Now, while in some particulars, the shell, which I have decided 
to identify as the S. glans of Kuster, does not coincide with either his 
figure or description it is quite like both, so near in fact that I do not 
believe we shall ever find any species of the genus that will answer 
better, hence it seems to me best to fix upon this form and so 
definitely establish the status of Strophia glans. 
HABITS AND DISTRIBUTION. 
1 found the type form of Strophia glans in some fields which lie 
directly south of the little settlement of Fresh Creek, but on the 
opposite side of the creek, in December, 1888, and again in 1893. On 
both occasions I found all of the forms described, but on my first visit 
I did not find the intergrades between this species and its sub-specific 
form given below. 
Form No. 1 occurs in the southernmost fields about a mile from 
the creek, while on the borders of the creek in some rocky fields is 
form No. 2, while No. 3 is found among the bushes which border the 
fields. The Acorn Strophia lives on small shrubbery and on herbage, 
in the fields and about them, and is rather scattering, nowhere appear- 
ing in great numbers.
