vol. xliii., p, 341.

Zoarium variable in shape, and in the general arrangement of 
of its anastomosing branches, which are more or less linear. Zooecki 
uniserial, almost uniform in breadth, oral extremity occasionally erect 
and fi'ee ; cells punctured in the younger, granular in the older 
colonies. Gonwcium (?) a cell rather more inflated about the aper- 
ture than ordinary Zooecia. 
Habitat : On Inoceramus sp. and on Terehratula hiplicata, Sby. 
This species is not abundant in the Red Chalk, yet I have met 
with some fairish examples. 
4. Stomatopora granulata (Edwards). Var. incrassata d'Orb. 
1852. Stomatopora incrassata d'Orb., Terr. Cret., vol. v., p. 837, 
pi. 628, figs. 9-11. 
1890. Stomatopora granulata, var. A, Vine, Quart. Journ. Geol. 
Soc, vol. xlvi., pi. 465. 
The Zoarium of this variety is much more stunted, more com- 
pressed, and more anastomosing than the normal form. I follow 
Mr. Waters in identifying the S. incrassata d'Orb. as a variety of 
S. granulata Edwards, as, irrespective of size, the two have many 
features in common. 
Habitat : On Terehratula hiplicata. 
5. Stomatopora longiscata d'Orb., pi. xvii., figs. 4a, b, c. 
1852. Ibid d'Orb., Terr. Cret. v., p. 839, pi. 629, figs. 9-11. 
1890. Stomatopora longiscata. Vine, Quart. Journ. Geol. Soc, 
vol. xlvi., p. 465. 
Examples of this species are rare in the Red Chalk, but I have 
come across fragments that may be reasonably placed here. This is 
one of the species previously noticed by Mr. Wiltshire from the 
bottom layer (C) of the Red Chalk, and which he characterised as rare.
