Echinus paucimiliaris , Greg. This is the specimen referred to 
as Toxopneustes Drohachiensis , Proc. Geol. Ass. II. (now 
in the Reed Coll.) on the authority of Prof. Agassiz, 
to whom it was submitted. Upper Red Crag, Butley 
Mill. 
Echinus norvegicus , Sars. Fort William, Irish Estuarine 
clays, Magheramorne, Lough Larne. 
Sphcer echinus bredspinosiis , Lam. Mid-pleistocene, Selsey, 
Sussex. 
Strongylocoitrotus drohachiensis , Mull. Cor. Crag, Aldborough, 
early pleistocene, Bridlington, common in the Western 
Scottish series, raised beach, Portrueh. (see E. 
paucimiHaris) Some worn plates of this species were 
described by Messrs Crosskey and Robertson as a 
new species, E cumbraensis , a name afterwards 
withdrawn. Up. B. Cl. Cheshire. 
Strongylocentrotus Cotteaui , A. Bell. A very depressed 
Echinoid is sometimes met with in the Cor. Crag and 
is unlike any other with which I have been able to 
compare it. It follows the tuberculations of E . 
Woodwardi in some degree, but differs essentially 
in the proportions of height to breadth, the very 
fine example from Aldborough in the Woodwardian 
Museum being exceedingly flattened on the upper 
surface unlike the conical test of E. Woodwardi. If 
the Cambridge specimen here referred to is the one 
assigned by Dr. Gregory to S. drohachiensis , Proc. 
Geol. Ass. XII., I fear that I cannot concur in the 
attribution to the latter species, S drohachiensis being 
essentially a Northern form 
Strongylocentrotus lividus , Lam. Chillesford series, Sudbourne 
church walks. Pleist. Langbank, N B. 
Strongylocentrotus scaher , Greg. Coralline Crag, Aldborough. 
Irregular. 
Echinocyamus pusillus , Mull The type form of this 
polymorphous urchin ranges from the passage or basal 
beds of the Red Crag at Walton Naze to the 
Chillesford sands of Aldeby. The only recorded 
pleistocene localities are the Selsey “ mud deposit ”
