MONOGRAPH OF THE GENUS STROPHIA. 
color of the aperture, the violaceous externally, and the rather widely 
separated, prominent, white striations. 
DISTRIBUTION AND HABITS. 
I found this very handsome Strophia on the scattering shrubbery 
that grows on the rocky plains between the elevations that skirt the 
southern shore of Inagua, and the extensive salt lake of the interior, 
about twenty-five miles from Mathewstown. 
This was during the very dry month of February, and they were 
fastened to the stems of trees and bushes. 1 think their range is some- 
what further extended on this shore, but how far I cannot, at present, 
state.

Pallid Strophia. 
Plate II, 14 & 14a, shell. 
DESCRIPTION. 
Sp. Cii. Size, medium. Shell, thin. Striations, present. The 
whirls are 11. The teeth are two, and very short. Examined 25 spec- 
imens. 
Form, a pointed cylinder, the first whirl measuring most in diame- 
ter and each of the next four is less in size, then the remainder taper 
to a short point, forming an angle of about 60 degrees. The stria- 
tions are not numerous, 14 on the first whirl, rather regular, but not 
arranged m lines; they are slightly inclined from right to left, and the 
interspaces are one third wider than the prominences. The striations 
are not furrowed and the edges are rounded. 
Aperture, very large and open and the walls within it are so thin 
that the striations can be seen through them. Lower tooth, not prom- 
inent, .03 high by .08 long, and its position is a little to the right of the 
centre; the upper is placed high and is not prominent 
Margin, not produced forward beyond the diameter of the shell, is 
straight, very thin, with the edges slightly rolled backward. The front- 
al bar is moderately well developed and the elevated striations appear 
within it. 
Color of shell, externally, flesh color, deepening to pale purple on 
the two upper whirls; margin, striations, and apex, white; internally, 
pale purplish.
