ADDITIONS-RECENT SPECIES. 253 



D. FILUM Sowerby (p. 118). 



To the synonymy of this species should be added : D. funiculus 

 Brugnone, 1877 (see p. 204) of the Italian Pliocene, and D. Iceve 

 Hilgard & Hopkins, 1878 (p. 217) from the Pleistocene of Louis- 

 iana. 



Jeffreys (P. Z. S., 1884, p. 147) adds the locality : off Sahara, 

 1,261 fms. (Talisman Exp.). 



D. STEARNSii Pilsbry & Sharp. 



New name for D. simplex P. &. S., 1897, not D. simplex Miche- 

 lotti, 1861 ; see p. 125. This little species now has the honor of 

 bearing the name of a life-long student of West American mollusks. 



D. hyalinum " Leach MS. in Brit. Mus.," Sowerby in Conch. 

 Icon., pi. 7, f. 49 (Antalis hyalina Clessin) is a smooth species with 

 the apex and slit much as in D. splendidum ; locality unknown. 

 As the name is preoccupied by Philippi, and the specific value of 

 the form is doubtful, it had better be dropped. 



" D. eredum Verkrz., Jam." of Paetel's Catalogue, i, p. 593, is 

 unknown to us. There is an erectum of Sowerby, but it is from 

 Australia, not Jamaica.

 known to us.
