The eggs of this species are deposited in hemi- 

 spherical white masses, from i to 2 mm. in 

 diameter, which are of frequent occurrence, 

 attached to various objects. For the identity 

 of these eggs, we rely on the records of Mr. 

 T. E. B. Pope, who observed several of the 

 mollusks depositing them upon the egg cap- 

 sules of Urosalpinx cinercus, July 7, 1911.
