** PHASIANELLA.” 253 
the name in collections from the Lincolnshire Limestone generally. The small 
variety, as above described, is fairly abundant in the Lincolnshire Limestone 
at Weldon, and there are also forms which seem to connect it with the preceding, 
such as fig. lla. This particular specimen happens to display striato-punctate 
structure, reticulating with lines of growth, reminding us of Littorina punctura, 
Bean.

The following is the author’s description : “ Shell with the whorls (six) convex ; 
spire elevated, apex acute, the last whorl very large and ventricose, aperture 
oblique, base narrow.” It differs but little from P. parvula. The whorls in some 
specimens, such as the one figured (fig. 13), are rather less convex. Occurs in 
the Lincolnshire Limestone at Ponton, and perhaps also at Barnack and Weldon, 
and is probably only a local form.

Bibliography, §c.—The small shell of Eparcy (10 mm.) originally described by 
d’Archiac has relationships in the Inferior Oolite as well as in the Great Oolite of 
this country. The specimens from Minchinhampton, referred by Morris and 
Lycett to d’Archiac’s species, are very much larger, and as a rule have a slightly 
higher spire and more tumid whorls than the type.
