dered as the lower extremity or organ of attachment of this species 
of pentacrinite, I anxiously examined Mr. Harford’s fossil, with the 
hope of discovering its inferior extremity, but without success : even in 
this very large mass, nothing of this kind was discoverable. 
Small slabs of the remains of this animal are found in various parts 
of England, particularly in Dorsetshire, where, in several parts of the 
cliff on the sea-shore, the remains of the animal are found attached 
to the rocks in a pyritified state, in very considerable quantities ; but 
it very rarely happens that any pieces much larger than the two hands, 
and at the same time in tolerable preservation, can be separated from 
the rocks. 
But the vertebrae of different pentacrinites are much more fre- 
quently found in a detached than in an united state. They are often 
found in this state in different parts of Gloucestershire, Leicestershire, 
Northamptonshire, Lincolnshire, Somersetshire, Warwickshire, West- 
moreland, Cumberland, Yorkshire, and Lancashire. They are most 
commonly found in the bottom and sides of streamlets, and in the 
gravel of the rivers and sea, having been washed from the banks. 
Dr. Woodward observes that they are found plentifully in two banks 
at Whitton, in Lincolnshire, where the people call them Castles and 
Apostles. They are also frequently found in elevated situations ; thus 
they very much abound on Breedon Hill, in Worcestershire, and on 
Lassington Hill, near Gloucester, where they have obtained the name 
of Lassington Stones. Both these and trochital vertebrae, from having 
been found in abundance in particular streams, have, from time 
immemorial, given particular names to such streamlets : thus a brook 
at Strickland Head, in Westmoreland, has hence obtained the name of 
Fairy-stone Brook. 
A curious inquiry, perhaps worthy of the heraldic antiquary, is, 
how far the origin of the heraldic symbol, the mullet, has depended on 
the frequent discovery of these pentagonal vertebrae ; since this sym-
