INDEX, VOLUMES II TO XVII. 



Ill 



Dentalium (Bull. I'Acad. Imp. Sci., St. Petersb. [5], vii, 1897, p. 

 214). 



Dentalium alternans Miill. (p. 224) is probably the same as 

 D. alternans Ryck. (p. 220). See Holzapfel, Palreoiitographica, 

 xxxiv, p. 178. As the name is preoccupied, D. confusum S. & P. 

 will replace it, D. muellerianum becoming a synonym. 



Cadulus obrutus Conrad (p. 238). Add reference : Gadns 

 obrutus Conr., Amer. Journ. Conch., V, p. 227.
