 I he hgure referred to by Swainson in his description of Ifun- 

 adea is obviously not what that author intended, as the type of 

 the subgenus and the particular reference are no doubt a clerical 

 error, as he subsequently^ refers to the shell indicated as a true 

 Murpa, in which genus it should unquestionably be placed. Under 

 these circumstances it is desirable to adopt the suggestion made 

 by M. Cossmann,3 and select the following species as the type 

 01 the subgenus.
