[Abstract.] 



This communication contained notes on several species of Cre- 

 taceous corals. The author considered that Smilotroclius insignis of 

 Duncan must be referred to the genus CeratotrocJms ; that JS. grami- 

 latus. Duncan, was founded on immature specimens of Trochocyathus 

 Wiltshirei, Duncan ; that Micrahacia Fittoni, Duncan, is a variety 

 of Gyclocyathus Fittoni ; that the genus Podoseris, Duncan, and pro- 

 bably Syzygojyhyllum, Eeuss, are the same as Rliizangia, M.-Edw. 

 and Haime, and consequently P. mamilliformis, Duncan, and P. 

 elongata, Duncan, are species of Bhizangia. He further stated that 

 Turbiiioseris, Duncan, is identical with Leptopliyllia, Eeuss, and 

 as the specific name de Fromenteli is preoccupied in the latter genus, 

 he proposed to substitute the name Lej^tojpliyllia cmglica, Tomes, for 

 Turbinoseris de Fromenteli, Duncan. A new species, probably of 

 Smilotroclius, from the Gault of Eolkestone, and a new Isastrcea from 

 Atherfield were described, and notes added on the occurrence in 

 British localities of Barysmilia tuberosa, Eeuss, B. Cordieri, M.-Edw.
