Pl. 18, fig. 19, p. 82. 

Vesicular cup-corals. 
Cystiphyllum, Lonsd. In this cup-coral the 
septa, though not absent, are quite subor- 
dinate to the vesicular structure, which 
takes the place also of the regular tabule, 
or rather represents them. 
A fine section to shew structure. 
Cystiphyllum Grayii, Milne Edwards, t. 72, 
fig. 3. The original figured specimens are 
in this collection and are marked. 
Cystiphyllum brevilamellatum, McCoy. A 
somewhat doubtful speeies. McCoy seems 
to think Lonsdale’s pl. 16 bis, fig. 2, Sil. 
Syst. may be this species. 
Cystiphyllum cylindricum, Lonsd. (Milne Edw. 
Brit. Fos. Cor. t. 72, fig. 2, also Siluria, 2nd | 
ed. pl. 38, fig. 3). 
Cystiphyllum Siluriense, Lonsd. (Siluria, 2nd 
ed. pl. 38,-fig. 1). This wide species fre- 
quently has accessory roots like the Om- 
phyma (p. 113). 
| Cystiphyllum, ew sp. Compressed, and largely | 
vesicular, one specimen shews the growth of 
seven buds from the calyx. 
| Paleocyclus, Milne Edwards and Haime. A 
genus of pretty discoid corals, of very small 
size; which from their external character 
were long regarded by Edwards and Haime 
as representatives of the Fungide or mush- 
room corals, and as the only coral of the 
order Aporosa in Silurian times. It really 
belongs to the Rugosa (Duncan). 
Paleocyclus porpita, Linn. (Milne Edwards, 
Brit. Fos. Cor. t. 57, fig. 1). A circular and 
very depressed money-like species. Very 
common in the Dudley limestone.
