shell behind it, with the edge beveled and produced into a sharpened 
edge, which is, however, not rolled backward. The frontal bar is not 
well developed, not protruding beyond the striations, but completely 
interrupts them. 
Color of shell, externally, ashy throughout, striations and all ; 
internally, pale brown, becoming paler on teeth and margin. 
DIMENSIONS. 
Size of type, .92 by ,45. Largest specimen, 1.05 by .50; small- 
est, .77 by .40. Greatest diameter, .50 ; smallest, .40. Longest 
specimen, 1.05; shortest, .77. 
OBSERVATIONS. 
Individual variation is toward a larger shell, with a thicker 
margin and with more striations, but not in any marked degree, on 
one hand, and toward a smaller form with a thinner margin and fewer 
striations. 
This singular Strophia may be at once distinguished from any 
other by the peculiar ashy color, which in many specimens has a 
decidedly bluish cast, but more particularly by the wide apart, 
irregular striations, which, being inclined in different degrees, give the 
shell a singularly rough appeal ance. in -4b- much so, that I know of no 
shell of this germs that approaches it in these particulars. 
This species often occurs in collections labeleld as S. glans, but 
the glans of Kuster, ns figured by him, as cited, under that head, 
further on in this monograph, is a white shell, with rather numerous, 
quite regular, striations, and dees not at all resemble 8. neglecta, 
excepting possibly in being of an oval form. 
IIABITS AND DISTRIBUTION. 
In January, 1 8S4, I found the Neglected Strophia on the borders 
of a deserted plantation on New Providence about a mile west of 
Fort Charlotte. Here they were abundant, clinging to t' e bushes, 
and were also on the fence that divided the plant- a tie 1 1 f n m the road 
that runs from Nassau to the westward. All gathered in this 
locality at that time were typical. 
Nine years later, in A* arch. 1875.1 visited the spot and found 
the plantation recuhivated. The hushes were uprooted, and the 
entire locality changed into sisal hemp fields. On these plants,
