and the raised beaches about Chichester. It is also 
found in the submarine accumulations of the Turbot 
bank, Co Antrim. The varieties “ angulosa , rotundus , 
and triangularis , Greg., are Walton forms. E. 
hispidulus, E F., Cor. Crag and Walton passage beds, 
and var. Suffolciensis , Ag , common to all the Red 
Crags are hardly divisable from the typical species. 
Cotteau on the other hand instituted a new species, 
E. Forbesi, considering Forbes was wrong in his 
corrections of the Crag species with E. pusillus. 
E. oviformis, E. F , Cor. Crag to Chillesford beds, 
may be a distinct species. 
Rhyncopygus ( Echinarachnius) Woodi , E. F. This very rare 
species is only known by a few fragments, from the 
Coral Crag, Aldborough, the Walton passage beds, 
and the Red Crag of Sutton. One of Forbes 
examples may prove to be another species should 
perfect specimens ever be found. 
Echi nolamp as subrostratus , Greg. The only example of this 
species in the Brit. Mus. is said to be from the 
Cor. Crag, Suffolk. In the absence of any definite 
information as to its locality, I fear that this 
interesting species has no claim to be considered 
British, as the matrix to which it is attached is 
totally unlike any of the English Crags, indurated 
or otherwise. It may be a Belgian miocene Tertiary 
from, the genus being tolerably common in Belgium. 
See Lyell, Belgian Tertiaries, Q. J. G. Soc. 
Agassizia equipetala , Greg. This is another species of uncertain 
origin, the matrix being unlike the usual run of the 
Crag. Recent and fossil the genus is only known 
from the West Indies and N. America, and till 
further evidence is forthcoming as to the genus 
occurring in England, some doubt must attach to its 
genuineness as a British fossil. Coralline Crag, 
Aldborough, (Brit. Mus.) 
Brissus unicolor , Leske ( B. Scillce, Ag.) Rare in all horizons 
of the Cor. Crag.
