FROM THE INFERIOR OOLITE. 513 



ribs. Surface broken by occasional prominent growth-lines, which 

 become more numerous near the margins, where small, indistinct, 

 subsidiary ribs start in the centre of furrows. 



Dimensions. 4|- inches long, by 5| wide, and 2| deep for both 

 valves. 



One specimen in the British Museum, from Brockhall, Northamp- 

 tonshire. 



This shell approaches Lima majestica in size and shape, but is 

 less compressed or pinched, and longer ; its ears are not so com- 

 pressed, the surface is more regularly convex, and the lima-line more 

 rounded, much less prominent, and shorter, so that the greatest 

 depth is at a point one quarter of its diameter in rear of it. The 

 plaits are also very different, being fewer and higher, with broad, flat, 

 smooth interspaces, and becoming much more crowded on the pos- 

 terior ear. The growth-lines are lamellar, becoming near the 

 margins irregularly crowded and foliaceous.

This shell appears to be very common in the Lower Oolites. 

 Lycett, in his ' Cotteswold Hills,' quotes it from the Upper Lias 

 Sands, the Gryphite Grit, and the Trigonia-Grit, as well as from 

 the Great Oolite of Minchinhampton. Sharp also gives it from the 

 Lincolnshire Limestone and the Northampton Sand. The speci- 

 mens which I have collected from Dan dry, Cleeve Cloud, &c, seem 

 to approach Laube's figure much more nearly than the Great-Oolite 

 specimens, which are more angulated and depressed anteriorly, as well 

 as smooth. Morris and Lycett, however, state that the smoothness 

 increases with age. In 1850 D'Orbigny, in his 'Prodrome,' Sect. 13. 

 No. 395, had given the name L. bellula to a distinct twelve-ribbed 

 species ; and as he has priority, Laube has changed Lycett's name. 

 The shell appears to be very like Lima gigantea, Sow. 



Terquem and Jourdy's figure of an aged shell show well-marked 

 rays, though both they and Morris and Lycett describe it as be- 

 coming smooth when adult.

I have an imperfect shell from the Humpliriesianus-zone of Dun- 

 dry, which appears to belong to this species ; and there is another 

 in the British Museum from the Inferior Oolite of Stroud.
