PRIDEAUX’S MODIOLA. 
Hinder part of the shell with elongated cancelli; hinder 
side with a rounded wing; anterior side towards the 
middle, broadly sinuated. 
The discovery of this beautiful little shell (which does 
not exceed a quarter of an inch in length), is due to C. 
Prideaux, Esq. of Kingsbridge: several specimens were 
found by that gentleman amongst sand, from Milton on 
the southern coast of Devon, and it is named after him; 
a tribute due to one of the most zealous and active investi- 
gators of the marine zoology of Britain.

This section contains several obscure species, which have 
been confounded together under the titles of Mytzlus dis- 
cors. Montagu describes two species as natives of Great 
Britain: one he has named M. discors, (but I am by no 
means satisfied that it is the discors of Linné); the other, 
which is a very distinct species, discrepans.
