[Palzocyclus preacutus, Lonsdale, is the May | 
Hill Sandstone species, see p. 84 I do 
not remember that it is found in Wenlock 
strata except in 8. Wales.] | 
Paleocyclus Fletcheri, Milne Edwards (Brit. 
Fos. Cor. t. 57, fig. 3). A conical cup- | 
shaped species, more like Petraia than any 
other. The buds take their rise from the 
surface of the cup. 
Palzocyclus rugosus, Milne Edwards (Brit. Fos. 
Cor. p. 248, t. 57, fig. 4). 
Clisiophyllum vortex, McCoy, said to be from 
the Wenlock limestone—is without doubt 
the mountain limestone sp. C. coniseptum, 
Keyserling. Milne Edwards (Brit. Fos. Cor. 
t. 37, fig. 5). A common fossil in collections. 
ECHINODERMATA. 
Lepidaster, Forbes. Mem. Geol. Surv. Decade 3 | 
(distinct from Paleaster). 
Lepidaster Grayii, Forbes. Decade 3, pl. 1. 
Two fine large specimens. 
Roots, and stems (often swelled by disease) are 
extremely common, so common as to cha- 
racterize the whole formation. Separate 
plates of various genera are less common, 

but are found in the more shaly strata. 
I adopt the order in which the genera are given 
in the Synopsis for convenience of reference. 
But it is not a natural order. Some genera | 
have been since added; and many more 
remain to be described from the magnifi- | 
cent Fletcher Collection, and that of Mr 
John Gray of Hagley, now deposited in 
the British Museum. Mr C. Ketley of 
Smethwick has added largely to both col- | 
lections, both cystides and crinoids. |
