The white network with which this shell is described 

 as being covered is ]>robably an extraneous growth, 

 but the form is peculiar, and there are not the usual 

 spiral strife.

I am not fully acquainted with the grounds upon 

 which it is judged right to pilace this species in the 

 present genus, but I am assured that tlie animal is 

 a true Scaphander.
