Some of the species in the foregoing table are also met with in the 

 Great Oolite of Wiltshire. A few are here and there, though rarely 

 found;, in the whole of the freestone, and others range indiscrimiDately 

 throughout the group, especially Area ovata, Avieula eomplicatay 

 Peeten vimineus^ Cidaris subangularis, and Echinus germinans. In 

 addition to these, there are several others which have not been deter- 

 mined ; and the following appear, as far as is at present known, to be 

 among the more characteristic species limited to the freestone : — 



t One of these with a smooth shell, not uncommon in the shelly freestone, is 

 described as P. lata by Mr. Sowerby, but Mr. Lycett identifies it with a new spe- 

 cies in the great oolite. It has generally lost the shell. 



It is worthy of notice, that the collection of shells from the more fossiliferous 

 portions of the freestone, and of which so large a proportion agree specifically 

 with forms in the great oolite, presents an isolated series, the greater number 

 being evidently peculiar to the freestone, and affording many distinctive and re- 

 markable characters. 



X Solarium occurs in the oolite marl near Stroud, in the coral bed (oolite 

 marl) at Crickley, and in the lower strata of the inferior oolite at Dundry, and 

 near Ilminster, but the species differ materially.
