* Mr Edward Forbes considers this as the young of the A. tetragona of 

 Turton; but it differs much in size and appearance, both from the figure 



g'ven by him in his Malacologia Monensis, and by Turton in his British 

 ivalves. 



-f- This shell, found by Captain Portlock in stratified beds in Ireland at an 

 elevation of 400 feet above the level of the sea, he considers to be an un- 

 known species. 



* { I observed a specimen of this shell in the museum at Newcastle, erro- 

 neously named N. pallidula, from the brick-earth, Norfolk. It is described 

 and figured by Mr Forbes, Malacologia Monensis, p. 31, pi. 11. fig. 6, 7.
