Tlie shell of the tenth edition of the Sy sterna, as Hanley observes, raay 

 be an immature specimen of Richmla spectrum, but there is no proof 

 that it is, for the quoted figure of Riimphius hardly represents it, and 

 there is no such shell in the Linne;in cabinet. On the other hand, 

 neitlicr the description nor the quoted figure fits the manci7iella, auct. 



Considering the confusion surrounding Linne's jMurex mancinella 

 I am inclined to disregard it and to apply names to the shells which 

 have been so designated, about which there is no doubt. Mr,,C. Hecllev ._ 

 has already come to the same conclusion.' fl^^^^'^^'^^^Ji / • '^P m
