MONOGRAPH OF THE GENUS STROPHIA. 
Aperture, large and open, measuring a trifle more just within than 
at the entrance. Lower tooth, not very prominent, .03 high by .12 long, 
and its position is just a little to the right of the center; the upper is 
placed well above it but is a mere protuberance, yet this slight elevation 
makes a complete turn around the column. 
Margin, not produced beyond the diam- 
eter of the shell, is not inclined to the right, is 
very thin, measuring .03, but the edge is not 
rolled backward. The frontal bar is not well 
developed and is smooth within. 
Color of shell, externally, white, conspicu- 
ously spotted and flecked with very irregularly 
formed markings of purplish; internally, pur- 
plish brown which gradually fades into flesh 
B color on the teeth and margin.

DIMENSIONS. 
Size of types, 1.23 by .54. Largest specimen, 1.40 by .56; smallest, 
1.10 by .48. Greatest diameter, .56; smallest, .48. Longest specimen, 
1.40, shortest, 1.10. 
OBSERVATIONS. 
There is considerable variation in respect to color and extent of 
markings, some are darker than the type and some are paler; in the type, 
the colored portions are about equal to the white, but in some cases, 
the purplish predominates, and in some, especially in paler colored spec- 
imens, the spottings are comparatively few and consequently the white 
is in excess. The aperture is also inclined considerably to the right in 
some shells. 
As a rule, however, the species is quite uniform in form and mark- 
ings. 
Known from all others, by the large size, prominent striations, 
open and thin-margined aperture, and conspicuous markings. 
DISTRIBUTION AND HABITS. 
The Flecked Strophias occur in the interior of Rum Key, where 
they are not very common, living in isolated groups in rather exposed 
situations, but among foliage and plants. The specimens collected were 
obtained on the western side of the island but I am, at present, unable 
to give the exact range of this and the preceding species, yet should 
judge that the habitat of both is comparatively extended.
