Star corals,

(True Corals). with stony 
bases to cells.

Palewopora, p. 16. 
Paleopora, p. 17. 
Graptolites, sp. With simple not recurved cell- 
mouths. Very common. It is possibly G. 
colonus, Barrande, in Lower Ludlow, but 
more likely distinct. 
ZOOPHYTA (CELENTERATA, Huxley). 
Tabulata, or Millepore Corals. 
Fistulipora decipiens, McCoy (Ann. Mag. N, 
Hist. 2nd Ser. Vol. vi. p. 285). The cell 
tubes are so minute, and the interstitial sub- 
stance too like a sponge. 
Heliolites, Dana. A common Wenlock fossil. 
Millepore corals allied closely to the Helio- 
pora cerulea of V. D. Land. Cell tubes set 
in a mass of cenenchyma, i.e. pointed small 
tubes of much less diameter than the cells. 
Species numerous. 
Heliolites interstincta, Wahl. (Siluria, 2nd ed. 
Foss. 18, figs. 3—5, pl. 39, fig. 2. Milne 
Edw. t. 57, fig. 9). Incrusting on shells (Or- 
thoceras, or spiral shells chiefly) or amor- 
phous or pyriform when grown in rapidly 
accumulating mud. In fact, it assumes all 
shapes, like a Proteus, according to circum- 
stances, and ranges from Middle Cambrian 
to Ludlow rock. 
Heliolites, var. Murchisoni, Milne Edw. Brit. 
Foss. Cor. tab. 57, fig. 6. 
Heliolites megastoma, McCoy (Sil. Foss. Irel. 
pl. 4, fig. 14). Siluria, 2nd ed. 1859, wood- 
cut 27, fig. 7. Easily known from the last 
(not so common) by the very large close set 
cups. (Milne Edw. t. 58, fig. 2). 
Heliolites petalliformis, Lonsd. (Plasmopora, 
Milne Edw. Brit. Foss. Cor. p. 253, pl. 59, 
fig.1. Siluria, 2nd ed. Foss. 18, fig. 2, pl. 39, 
fig. 4). Regarded as a distinct genus (Plas- 
mopora) by Milne Edw. The distinctions 
seem too minute to be more than specific. 


Wenlock shale? b. 668, 
Dudley, F.C. Itis possible 
this comes from the Lower 
Ludlow shale, above the 
workable limestones. The 
species abounds near Lud- 
low.
