Billockby. Upper Glacial, Bridlington (Woodward). 
In the Cor. Crag young specimens are very abundant, as they are also in the Middle 
Glacial sands of Hopton and Billockby, and, unlike the general condition of the fossils of 
those sands, they are usually uninjured. his species occurs in the Fluvio-marine Crag 
of Bramerton, though rarely, but it is common in the Chillesford bed, where that bed is 
not in the Fluvio-marine condition, as at Aldeby and Bramerton; but I have not met with 
it where it is in the Fluvio-marine condition, as at Horstead, Burgh, or Coltishall, nor in the 
Lower Glacial sands. It is rare in the Red Crag.

Specimens of this shell have been sent to me by Messrs. Crowfoot and Dowson from 
Aldeby, and two young specimens have occurred at Hopton.

Localities. Cor. Crag passim. Red Crag, Sutton and Butley. Chillesford bed, 
Aldeby. Middle Glacial, Hopton. 
A specimen of this shell was sent to me from Aldeby by Messrs. Crowfoot and 
Dowson, and a solitary specimen was obtained by me from the Red Crag of Sutton, 
! A system now prevails of restoring to a species the earliest name given to it from the date of Linné’s 
12th edition of his ‘Syst. Nat.,’ however long such name may have been in disuse. This is only fair and 
just, and I have endeavoured to conform to such a rule; but why this custom should be adopted with 
respect to species, yet disregarded with respect to the more comprehensive divisions of the Animal 
Kingdom, I am at a loss to understand, and I still see no reason why Linné’s term of Bivatvia should 
be superseded. ;
