Mr. Cumberland’s Descriptions of 
A polished specimen of the limestone of the Black Rock contain- 
ing one of these supposed heads, is represented in plate 2, fig. 1. 
After much research, Mr. Benton found in a crevice in these beds 
a specimen of one of these heads, which is now in Mr. Miller’s 
collection. This discovery proved the truth of the supposition, as 
it was evidently the section of a similar body which caused the 
marks before mentioned in the limestone. In these crevices, clay 
was found in which were many detached plates of the upper parts 
of encrini, apparently of different species, as well as portions of 
stems or trochitae, as they are usually called; among the latter were 
several of different species both cylindrical and pentagonal. Since 
that time, many gentlemen of this vicinity have sought with much 
activity for similar objects. Their activity has been rewarded with 
considerable success, as the accompanying drawings will shew. I 
will now proceed to describe these objects, noticing the spot where 
each specimen was found. 
Plate 2, Fig . 2. 
This specimen was discovered by mein the month of August, 
1816, in a shelf of decomposing limestone, near Woodspring Abbey 
Farm, in the neigbourhood of Whorle in Somersetshire. It is to be 
regretted that these bodies are generally much broken and injured, 
and it is very rarely that one is found as perfect as the present 
specimen. Its plates are of a lightish colour, and the limestone that 
fills it is much harder than that in which it was imbedded. 
Plate 2, Fig . 3. 
Is another of the same species, from the same limestone at Wood- 
spring. This species has probably some resemblance in its nature
