Planorfoulina Ungeriana D'ORB. 



Tab. VII, figg. 234236. 



Our form has the more distended shape of Plan. Haidim/eri D'ORB. but in all other 

 respects it falls in with Plan. Ungeriana of the same author. Sometimes it approaches 

 the subnautiloid form, but its most common shape is that of a bi- or plano-convex, 

 somewhat thick, lens with a blunt edge and rotaline arranged chambers. 



It plainly exhibits the very vague and faint distinction between the i>Anomaline 

 and Planorbuline types. Sometimes the shell is quite conical the aboral face being flat, 

 the other raised conically. The central bosses are often granulated, not seldom spread- 

 ing over a great portion of the shell around the centre and hiding the convolutions 

 and septal lines, which often are somewhat raised (limbate). At another times the 

 bosses are reduced to small specks of clear shell-substance.
