CAMPANULAHIA. 163 



root and branch, has a pale, horny, hyaline aspect. " The 

 stem is divided at regular intervals, as in the other species ; 

 but instead of several rings or twists above the origin of 

 the cells, there is a small internodal joint ; and the stalk of 

 the cell, instead of being ringed, consists of two or three 

 unequal joints, much as they are formed in the genus 

 Halecium. The cell itself is of the normal thin hyaline 

 texture, and bell-shaped, but the rim is sinuated on the 

 proximate margin, so that the aperture resembles very much 

 the mouth of a jug/' (Dr. Johnston.} 



As jugs differ in form, we may mention that it is a jug 

 of the common form, the rim of which is depressed towards 

 the handle, giving the mouth a scooped appearance.
