MEMOIRS. 
On severed new species of Encrinite and Hypanthocrinite from the 
neighbourhood of Dudley. From a report by the Curator of the 
Dudley and Midland Geological Society. 
In tlie observations wiiich the committee of tlie Dudley and 
Midland Geological Society made in tlie first report kid before the 
society, at its formation in January 1842, with regard to the com- 
plete series of fossils from the Silurian rocks of the neighbourhood 
which their museum at that period contained — complete, indeed, 
so far as the then existing knowledge extended — they ventm^ed 
to remark, that numerous as were the various genera and species 
already known, they yet felt confident that new discoveries in 
this interesting field would be continually mado, to reward the 
careful and persevering research which they hoped the establish- 
ment of this society would encourage. 
The fortunate results which have attended the researches of 
several of its members, even in the short period which has since 
elapsed, have fully justified these expectations. During the past 
quarter, several very beautiful and perfect specimens have been 
discovered of that peculiar fossil to which the curators alluded 
in the first report as partaking of characters allied both to the 
pentremite and encrinite, although essentially different from 
either. The body is composed of irregularly shaped plates. 
It is divided into four parts, by bands apparently running down 
from the top of the body, and reaching nearly, in some spe- 
cimens fully, to the point where the column and body join. 
In some instances, two of these divisions are larger than the 
others, and may be called the front and back of the fossil^ the 
two smaller divisions forming the sides. It is, however, possible 
that this apparent irregularity, which is not evident in every 
specimen, may result merely from unequal compression. Each 
of the four bands possesses a double row of small rays, and one
