5 "This great work is iuteuded to embrace a complete description and illustra- 



\ tion of the shells of moUuscous animals, and, so far as we have seen, it is not 



\ such as to disaj)point tlie large expectations that have heen formed respecting it. 



{ The figures of the shells are all of fidl size ; in the descriptions a carefnl analysis 



> is given of the labours of others; and the author has apparently spared no pains 

 ^ to make the work a standard authority on the subject of which it treats." —
