The object of this work is identical with Forbes and Hanley ^s 
celebrated History of British Mollusca ; but the high price of 
the latter and the mass of additional information gathered by 
Mr. Jeffreys were reasons sufficient to induce him to enrich 
our literature with a work which also in many other respects is 
distinguished from that of his predecessors. The work is 
illustrated by twenty-seven plates, the author having been obliged 
to limit the illustrations to representatives of each genus, in oi*der 
to diminish the cost of the work : the greater part are taken 
from drawings published in the works of Forbes & Hanley and 
of H. & A. Adams. The references are generally limited to the 
first author of the specific name and to Forbes and Hanley^s 
work, the remainder of the synonymy being reduced to occa- 
sional remarks. The descriptions are short, but quite sufficient. 
The author is guided by very sound principles as regards the 
nomenclature, the adoption or rejection of the older names, and 
* The second volume was not mentioned in the preceding Record, because 
it is dated 18(>d on the titlepage ; however, we have since been informed 
that it was really issued in lo(34.
