attached hemispherical body, consisting of a congeries of tubes 

 radiating from a common centre. This increases cyhndi'ically 

 and branches ; a longitudinal section then displays the tubes, 

 arising at the first centrally ^^dth a vertical direction, but afterwards 

 bending suddenly at nearly a right angle to reach the exterior ; 

 a transverse section would consequently divide the tubes through- 

 out a portion of their extent longitudinally, while in the centre 

 of the branch it would cut them transversely. The tubes are 

 subpolygonal with circular openings, many of which are nearly 

 closed^ owing probably to the more extended lives of some of the 

 polypes. 



This polypidom attains a height of several inches.

2. Heteropora septosa (var. o. polymorpha ; var. /3. pustulosa). 

 Sudbourn. | . | Britain. 



Polypid. boletiform, irregular, sometimes investing; pores irregular. 



One fossil specimen invests an EmarginvJa, and corresponds 

 with a recent British species in my possession upon an Area 

 lactea. 



Var. (i. is globose and pustuliform ; pores irregular, large and 

 small, suljpolygonal ; a section shows rows of tubes long and straight, 

 with transverse partitions like those in Chcetetes. 



1. Diastopora meandrina, n. s. 



Sutton. I ( 



Polypid. globosely foliaceous ; foliations anastomosing or meander- 

 ing with two layers of opposite cells ; cells tubular, slightly raised, or 

 rather strongly inclining towards the plane of axis, irregularly quin- 

 cunxial ; aperture orbicular ; surface granular ; radius one inch and 

 a half.
