74 MOLLUSCA FROM THE GREAT OOLITE. 



Phasianella elegans. Plate XI, figs. 27, 27a. 



P. Testa ovato-elongatd ; anfractibus (7) convexiusculis ; spird acuta, aperturd longiore. 



Shell ovately elongated, whorls (7) convex, the spire acute, larger than the aperture. 



The height of the last volution is rather more than the remainder of the spire ; the 

 whorls are narrow and convex; the sutures strongly impressed. Axis 16 lines, transverse 

 diameter 8 lines. 



Locality. The planking of Minchinhampton Common has supplied this species in 

 considerable numbers.

P. Testa ovatd, sub-globosd; spird parvd; anfractibus (6) angustis, convexiusculis, anfractu 

 ultimo amph; aperturd obliqud magna. 



Shell ovate, subglobose ; spire small ; whorls (6) narrow, convex ; the last whorl large ; 

 aperture oblique and large. 



The length of the aperture is greater than that of the remainder of the spire, and the 

 length of the last volution is twice as great as the spire. The variety of figure in this 

 species is more than usually considerable. Axis 12 lines, transverse diameter 8 lines. 



Locality. It is the most common of the Great Oolite Phasianella, and occurs in 

 all the shelly beds near Minchinhampton. 



Phasianella conica. Plate XI, figs. 30, 30a. 



P. Testa ovato- conica, acuta; spird mediocriter elatd, conica ; anfractibus (6) plants, 

 ultimo elongato; aperturd obliqud angustd. 



Shell ovately conical, acute; spire moderately elevated, conical; whorls (6) flattened; 

 the last whorl elongated ; aperture oblique and narrow. 



This species is somewhat spindle-shaped, narrowing at both ends ; the length of the 

 aperture is less than that of the spire ; but the last two volutions occupy more than two 

 thirds of the entire length of the shell. Axis 1 lines, transverse diameter 4 lines. 



Locality. It is not uncommon, and occurs in all the shelly beds, more especially at 

 Minchinhampton Common.
