48 BRITISH POSSIL CORALS 



resemble those of Astrocoenia gibhosa, nobis, from the Sutton Stone. The species I select 

 as distinguishable in the Azzarola deposits are — 



Rhabdophyllia Sella, Stopp. 



„ Langohardica, Stopp. 



„ Meneghini, Stopp. 



„ Be-Filippi, Stopp. 



Montlivaltia Gastaldi, Stopp. 

 Stylina Savii, Stopp. 

 Thamnastrcea Batarra, Stopp. 



„ Escheri, Stopp. 



„ Meriani, Stopp. 



„ rectilamellosa, Winkl. 



These Rhabdophgllia, StgUncB^ and Thamnastraa, are represented in the lowest zones 

 the British Lower Lias by Thecosmilia, Bhabdophgllia, and AstrocoenicB. 



The strata between the Trias and the Zone of Ammonites Bucliandi in Germany are 

 very uncoralliferous, and the determinations of the species given by Quenstedt are not suf- 

 ficiently exact. MM. D'Orbigny, Terquem et Piette, and De Fromentel, have noted and 

 described the following species from the Lower Lias, below the Zone of Ammonites Buck- 

 landi, Grgphaa incurva, &c., in France and Luxembourg, and by omitting Isastraa basal- 

 fiformis, De From., which belongs to the Zone of Ammonites planorbis, the following table 

 will give all the species from the Continental Zone of Ammonites angulatus .• —
