thirty-two new species have been added by M. Diiclos, 

 from the coast of New-Guinea. 



This genus is closely allied to Ancilla, which, how- 

 ever, is destitute of striae on the labium and the spiral ca- 

 nal is completely filled up. From Terebellum, to which 

 it is also allied, it may be distinguished by the striated la- 

 bium and columella, and the elevated band at the base of 

 the body whorl, and from Mitra and Vot.uta by the ca- 

 naliculated suture.
