The paper is followed hj a list of species, distributed by 

 Mr. Pease, under Lis MSS. names, whicli, on the authority of 

 Mr. Cuming, are regarded as synonymous with previously de- 

 scribed species. As several American conchologists have re- 

 ceived these species, we reprint the list. (As Mr. P. P. Car- 

 penter states, in a note to the paper: "It must be remembered 

 that Mr. Pease may have reasons for regarding them as dis- 

 tinct, which do not appear on the face of the specimens.")
