MONOGRAPH OF THE GENUS STROPHIA. 
75 
DIMENSIONS. 
Size of type, 1.42 by .55. Largest specimen, 1.27 by .58; small- 
est. 1.12 by .50. Greatest diameter, .50: smallest, .48. Longest spec- 
imen, 1.42; shortest, 1.12. 
OBSERVATIONS. 
This is a very uniform species, specimens varying very little from 
the type. I am not the first, by any means, to collect this species, as I 
have seen it in collections, but always labelled with the name of some 
other species, though why, I cannot well imagine, as it is one of the 
most strongly defined species found on the Bahamas. 
This species well represents the short toothed form 
of Strophia prevalent on the Bahamas and in some por- 
tions of Cuba; see Fig. 10, where I have given a section 
of S. alba, showing short tooth, and compare with Plate 
II, 1 b, where is given a section of S. pannosa, one of the 
long toothed species. 
Known by the large size, open aperture, short 
tooth, white color, prominent striations, and form as 
given. 
DISTRIBUTION AND HABITS. 
I found the White Strophia common on the west coast of Rum Key, 
near the salt pond, on the low shrubbery between it and the beach, 
frequently quite near the sand. At this time they were quiet, as the 
weather was dry.

DESCRIPTION. 
Sp. Ch. Size, large. Shell, not very heavy. Striations, present. 
'Teeth, two and short. Whirls, 11. Examined 150 specmens. 
Form of shell, rather cylindrical, with the first two whirls equal 
in diameter, and the third is but little smaller; from this, the shell slopes 
to an obtuse point, forming an angle of 65 degrees. The striations 
are numerous, 25 on the upper whirl, prominent, regular, but not ar- 
ranged in lines, and the interspaces are not as wide as the prominences. 
The striations are rounded but not furrowed.
