 Gemis Pyrula, Lauik. 



P. squamulata ?, Phil., an Rhizochilus antipatum ?. * Found 



about four miles disfant from the shorc of Maddalena 

 Bay, at a depth of 60 fathoms, attached to tlie stalks of 

 Aniipate scoparia. I have bcen assurcd by experienced 

 fishermen, that this locality abounds with madrepores, 

 retepores, and other coralloids. From the modification 

 observed in three specimens obtained from tbis locality, 

 though the animal is operculated, I bclieve it is stationary 

 on tbe stalks of Antipatc scoparia, as tbe aperture 

 becomes groovcd according to the convcxity of the samc* 



Pyrulce fossilcs. 



Casts of Pyrula are found in Bed No. 2, the yellow sand.
