CORALS FROM THE PERMIAN FORMATION. 149 
Family STAURID A, (p. lxiv.) 
Genus Pouyomuia. 
This genus, the establishment of which was proposed by Professor King some years ago, 
was characterised by that author in the following terms : 
“A simple Cyathophyllida. Form conical. Walls solid. Primary vertical plates 
converging to within a short distance of the centre. Secondary vertical plates reaching 
about half way to the centre. Transverse plates horizontal, at irregular distances from 
each other, and extending quite across the cavity. Chambers or lamellar imterspaces 
capacious compared with those of other Cyathophyllide. Reproduction within the 
polypiferous cup.” (Avg, ‘Aun. and Mag. of Nat. Hist.,’ Second Series, vol. i, April, 1849.) 
As we have stated here above, the genus Polyccelia has of late been abandoned by 
Professor King; but it appears to us that it ought to be adopted, and in the systematic 
arrangement of the polypi, published by ourselves in 1851, it has been included in the 
family of the Stauride. (See ‘Monographie des Polypiers Fossiles des Terrains Palao- 
zoiques, Précedée d’un Tableau Général de la Classification des Polypes,’ p. 162.)

“Calophyllum vermiform; gradually enlarging from the base upwards; transversely 
wrinkled and longitudinally striated on the outside. Vertical plates dense and somewhat 
apart from each other; primaries four; secondaries sixteen. Transverse plates horizontal, 
rather thick, and at irregular distances from each other. Polypiferous cell shallow. 
“The specimen figured, which is the only one of the species known to me, was 
procured at Humbleton Hill, in the upper bed of shell-limestone.” (Avng, ‘ Perm. Foss. 
of England,’ loc. cit.)
