No. 46. Limnza anGusta. F. 2. Edwards. Tab. XIV, fig. 6 a—4é. 
L. testa angustd, elongata, sub-turrita, quinquies vel sexies circumvolutd ; spird elevata, 
acuminata ; anfractibus convexis, lineis incrementi obscuré striatis : apertura ovato-oblonga, 
anticé sub-dilatatd, spiram in longitudinem parum superanti; plicd columellari crassd, 
tereti, parum eminenti, sub-tortuosd. 
If it were not for the thick, round, columellar fold, and the elongated aperture, I 
should refer this species to L. longiscata, which it much resembles. It is a narrow, 
elongated, sub-turreted shell, formed of five or six convex volutions, obscurely 
striated by the lines of growth; the spire elevated and pointed. The aperture is 
a longish oval, equal to half the length of the shell, and rather spread out in front ; 
the columellar fold is thick, round, not very prominent, and but slightly twisted. 
The long narrow shape of this shell separates it from every species except 
L. longiscata ; from the latter shell it is easily distinguished by the fold, so opposite in 
character to the broad, flat, sulcated fold which characterises that species. 
Size-—Axis, 1j inch; diameter, not quite 3 an inch. 
Localities —Hordwell; Headon Hill.

L. testa ovato-acuminatd, sub-turrita, levi; anfractibus septenis, convexiusculis, suturis 
conspicuis : apertura ampld, semi-ovali, spiram in longitudinem superanti ; plicd columellari 
rotundatd, minima, parum contortd, sub-proeminenti. 
A smooth, ovate, oblong sub-turreted shell, with a moderately elevated and taper 
spire; volutions seven or eight, slightly convex, separated by a conspicuous, but not 
deep, suture, and occasionally striated by faint lines of growth: the aperture rather 
large, semi-oval, a little dilated in front, and longer than the spire; the columellar fold 
rounded, small, slightly twisted, and not very prominent. 
The English shells correspond so nearly with M. Deshayes’s figures, and with 
some French specimens, for which I am indebted to that gentleman, as not to leave 
any doubt as to this identification, notwithstanding that M. Deshayes describes the 
aperture as very oblique, and the columellar fold as much twisted, characters which 
I have not found prominent either in the English or French specimens. 
Size.—Axis, 4-10ths of an inch; diameter, 7-20ths of an inch. 
Localities. —Hordwell; Headon Hill. french: Beauchamp, near Pointoise,
