near Hampstead. The specimen figured (Tab. IX, fig. ly, \h,) is from the former 

 locality ; it is the one drawn by Mr. Charlesworth in the ' Magazine of Natural History,' 

 vol. i, (new series,) p. 533, and forms part of Mr. Wetherell's valuable collection of 

 fossils from Highgate and the neighbourhood. 



The English shells are apparently young ; they are much smaller than the Dax 

 specimens, the largest I have seen cannot have exceeded 1*6 in. in diameter.
