COEALS OP 1HE LIAS OE ENGLAKD AEE S. WALES. 191 



Warwickshire Naturalists' and Archaeologists' Field Club in 1872. 

 Since that time a very considerable series of fossils has been obtained 

 from these King's-Sutton beds. Amongst them are the following : — 



Ammonites spinatus, not uncommon, Spiriferina oxygona. 



margaritatus, not uncommon. Pecten textorius. 



Harpax Parkinsoni. Cidaris amaltheus. 



With these are associated examples of the species of coral I have 

 here described, and three others, two of which are also described 

 here. The third one is a Thecosmilia ; but the examples which have 

 hitherto been met with are not sufficiently preserved to admit of 

 description. 



Cycloutes ctteulifoemis, n. s. (PL IX. figs. 2 & 3.) 



Corallum of a depressed cup-shape, rounded beneath, and having 

 a slight constriction immediately under the calicular margin. 



Calicular margin projecting, rounded, and a little everted. 



Calice ovoid and a little concave. Fossula central, small, abrupt, 

 deep, and elongated in the direction of the longest diameter of the 

 calice. 



Septa exceedingly numerous, thin, straight, equal, and moniliform, 

 and so closely placed together that no interval is visible between 

 them. 



There is no epitheca. 



Height of the corallum 9 lines. 



Greatest diameter of the calice 1 inch 4 lines. 



Two specimens have been obtained from the Middle Lias of King's 

 Sutton, Northamptonshire — one of them by myself and the other by 

 Mr. J. Griffin. They were associated with the same Mollusca as 

 the species I have described as Thamnastvcea EiJieridgi. 



ASTREID^E. 

 MONTLIVALTIA EOLIACEA, U. S. (PL IX. fig. 10.) 



Corallum irregularly ovoid, much depressed, broadly attached, and 

 expanded laterally into a thin undulating somewhat foliaceous, 

 but not everted, outer margin. 



Wall horizontal, epitheca thick and rugose, with only feeble 

 indications of costse. 



Calicular surface slightly convex, uneven ; the fossula excentral, 

 shallow, and slightly ovoid. 



Septa rather irregular in thickness, not diminishing as they 

 approach the fossula, and having indications of lobes rather than 

 papillae along their margins. 



There are nine cycles and six systems. 



The septa of the primary cycle meet and unite in the centre of 

 the visceral space ; those of the secondary are nearly as long as the 

 primary ; those of the third are a little shorter than those of the 

 second, those of the fourth three fourths the length of the third,
