Fishes of the Genus Cliipen. 227 



tiie material a second time I find that such a genus cannot 

 be maintained, and that Clupea must be enlarged by the 

 addition of C. arcuata and tlie closely related C. melanoatoma 

 as well as by the species generally known as C. antipodum^ 

 but here called C, muelleri, Klunz., since reference to the 

 original description shows tliat the name C. antipodiun should 

 be given to the species recently described by rae as C, holodon. 

 The synopsis given in my former paper (Atm. & Mag. Nat. 

 Hist. (8) xviii. 191(), p. 3) may be modified to include the 

 three additional species.
