Height 6°5 mm., extreme width 5mm. 
Besides being considerably smaller than Bean’s species, this variety is rather 
wider in proportion to its height, but in other respects it would be difficult to 
separate them. But cf. Bulla globulosa, Cossmann. A single specimen in my 
Collection from the Scarborough Limestone. 
There is a specimen, also in my Collection, from the Inferior Oolite near 
Radstock, which has a height of 10 mm., and whose proportions accord better 
with those of Bulla undulata.
