MONOGRAPH OF THE GENUS STROPHIA. 
3 
I found these shells in the Museum collection bearing the simple 
label “ Havanna Cuba”. Beyond all doubt, this is the principal species 
which Ferussac had in hand when he described his Pupa chrysalis in the 
work cited at the head of this article, as his description clearly indicates . 
while his excellent figure, although the markings are a little darker in 
color, coincides almost exactly with the specimen which I have consid- 
ered typical and figured on plate I. Owing to the broad interpretation of 
what constituted specific characters which prevailed in his time, Fer- 
ussac included two quite different shells in his plates as this species, 
namely fig. 7 on plate 153, and 7-8 on plate- 1 56, but what these are, I 
have not yet determined. Thus the localities given by Ferussac, other 
than Cuba ( Guadaloupe and Martinique) are probably those of the other 
species figured. The size of Ferussac’s type is given by him as 35 mill, 
long by 13 mill, in diameter. Below I have given his diagnosis in the 
original Latin accompanied by a translation. 
“ P. testa elongata. turrita, cvlindrica, apice obtusa, longitudin- 
alifcer plicata, grisea, lineis fuscis angulatis ornata ; apertura ovato- 
rotunda, intus fulva, marginata, unidenfcata.” 
This may be translated as follows. Shell elongated, turreted 
cylindrical, apex obtuse, longitudinally striated, gray, ornamented with 
narrow, dark lines, aperture, round ovate, fulvus inside, margined, 
one-toothed.

DESCRIPTION. 
Sp. Ch. Size about medium, shell rather thick and heavy. 
Striations, present. Whirls, 11. Examined 29 specimens. 
Form of shell a pointed cylinder, the first whirl being the largest, 
then each successsive whirl is a little smaller to the fourth, from which 
the shell tapers more suddenly to a semi-obtuse point, forming an 
angle of fifty degrees. The striations are moderately numerous, 
twenty to the first whirl, but they are not very prominent. Are 
quite regular, but not arranged in lines. They are rather straight 
being curved slightly to the right at their lower terminations, and are 
slightly inclined from right to left. They are not furrowed, but rounded 
and polished, and the interspaces between them are twice their width. 
The aperture is not especially large, measuring but a little more with- 
in than at the entrance. Both teeth are represented by a mere tuber- 
cle scarcely to be seen even with the aid of a magnifying glass.
