114 GOES, RETIOULARIAN RrilZOPODA OF THE CARIHBF.AN SEA. 



Pulvimilina Michcliniana D'ORB. 



Tab. VIII, figg. 296298. 



Our ordinary form comes close to Eotalia truncatulinoides I/ORB, from the Ca- 

 nary Islands. Its prominent characteristics are its conical form, restricted number of 

 chambers, deep umbilicus and deep incisions between the umbilical prolongations of 

 the chambers. The chamberwalls are often nearly plain or so very little bent, that 

 the flat spiral side becomes obtusely angulous. The pores are not quite as fine as in 

 its congeners in general. 



It has been met with principally in the coralline-gravel, where it is common.

Polystomella crassilla WALK. var. Scapha FIOIIT. & MOLL. 



Tab. VIII, figg. 299300. 



Our form is usually very much compressed and starved. The aperture is narrow 

 and not easely discoverable. 



It is unfrequently met with in the chalk-ooze.
