AULACOPHYLLUM MITRATUM, Milne Edwards and Jules Haime, Pol. Foss. des Terr. Palzeoz. 
(Arch. du Mus., vol. v), p. 356, pl. ii, fig. 6, 1851. 
Corallum simple, turbinated, free, subpedicillated, thin, strongly curved; epitheca thin, 
and presenting slight circular wrinkles. 34 principal septa, rather thick exteriorly, 
extending mostly to the centre of the visceral chamber, and alternating with an equal 
number of rudimentary ones. <A furrow occupying the place of the septal fossula, not 
well defined, and indicated by the junction of the septa at the bottom of the calices. 
Height of the corallum 13 or 2 inches; diameter of the calice about 8 lines. 
Dudley, Walsall. Professor M‘Coy mentions also its existence at Coniston, Lancashire ; 
Applethwaite Common, Westmoreland; Mulock Quarry, Dalquorhan near Girvan, Ayrshire ; 
High Haume, Dalton in Furness, Lancashire ; Glyn Ceiriog, Denbighshire. 
This coral is also met with in Gothland. It does not present the characteristic 
peculiarities of Aulacophyllum in as distinct a manner as the other species of the same 
genus; but in adult specimens the pmnate arrangement of the septa is very evident. In 
A. sulcatum: they are much more numerous.
