Page 368, line 16 from bottom, add : "Additional specimens kindly submitted by Mr. Aldrich 

 seem to indicate that Polymices onusta Whitfield is distinct from Natica 

 aperta of the same author, though this does not settle in the negative the 

 question as to the presence of a callus in some specimens of A'', aperta. As 

 the specific name of the latter is preoccupied in its own subgenus, and its 

 chief distinguishing characteristic is the strength and prominence of the in- 

 cremental lines, I propose for it the name of Polynices {Mammilla) rugi/era. 

 P. onusta seems to be referable to the sub-genus Neverita."

NOTE. 



For the benefit of foreign readers, it may be noted that the lower part of the Chatta- 

 hoochee River is known as the Appalachicola; different maps give in some cases a different 

 extension to these two names.
