GASTEROPODA. 75 
PHASIANELLA AcuTiuscuLA. Plate XI, figs. 28, 28a. 
P. Testa ovato-conicd; spird elatd, acuté; anfractibus planis, angustis; anfractu ultimo 
ovato, magnitudine modico. 
Shell ovately conical; spire elevated, acute; whorls flattened, narrow; the last whorl 
ovate, its size moderate. 
The figure most nearly approaches to P. conica, but it is less gibbose ; the spire is 
more acute, elevated ; the whorls less numerous and narrow. 
Locality. It is not uncommon, and is found in all the shelly beds near to Minchin- 
hampton. 
PHASIANELLA NucIFoRMIS. Plate XI, fig. 26. 
P. Testé ovato-elongatd; spird parva; anfractibus (6) subpianis, ultimo elongato ; 
apertura angustata. 
Shell ovately elongated ; spire small; whorls (6) flattened, the last elongated ; aperture 
narrow. 
The length of the aperture is equal to that of the spire; the spire is acute ; the volutions 
very narrow, except the last two turns, which are much elongated. Axis 9 lines, transverse 
diameter 5 lines. 
Locality. It occurs in the planking of Minchinhampton Common, but is rare. 
PHASIANELLA PARVULA. Plate XI, figs. 29, 29a. 
P. Testé parva; spird elatd, apice acuto; anfractibus (6—7) planis aut subconvevis, 
angustis; anfractu ultimo subgloboso; apertura obliquad; columella arcuaté. 
Shell small; spire elevated; apex acute; whorls (6—7) flattened, or rather slightly 
convex and narrow ; the last whorl globose and large; the aperture oblique and oval; the 
columella curved at its base. 
The length of the aperture is two fifths of the entire shell ; the whorls are more numerous, 
and the apex more acute, than is found in the other Great Oolite species ; the aperture is 
rather small and contracted at its base. Axis 5 lines, transverse diameter 24 lines. Rare. 
Locality. Minchinhampton Common.
