 The series nnder notice, figs, aa-dd, are dimor])hoiis varieties, 

 showing the transition from rcLatively broad-chambered Pla- 

 nuhiria' to those with extremely narrow, elongate, and sub- 

 parallel chambers, and having their original Cristellarian 

 growth more and more definitely succeeded by subscfjuent 

 chambers set on at a considerable angle, as on either side of a 

 FlaitUina.

This may be accepted as the Nodosarian fonn of l^extularia 

 (jihbosa ; that is to say, it is a short stout variety oi' Bi(/enenna 

 with somewhat irrcLrular inflated chambers.

 young shell seen edgcAvise, and showing only the edge of the 

 first chamber and the aperture of the second.
