Distrib. — Lower Greensand : Farringdon. 
Aff. — The type-specimen from the Neocomian of Elligser Brink, Hanover, as 
figured by Koch & Dunker, is clearly not a Bryozoan. The specimen from the 
Lower Greensand of Farringdon, identified as Heteropora clavula by Etheridge & 
Newton, is a Heteroporid. It has an elegant, club-shaped zoarium, 13 mm. 
high, 5 mm. in diameter above, and with astern 2-2 mm. in diameter. It may 
be a new species of Fungella.

Char. — Zoarium of thin dichotomising branches (2-5 mm. diameter). Surface 
smooth, but an indication of faint annul ation. Apertures pentagonal. 
Mesopores in a single line between the apertures.

2 The Ceriopora dichotoma of Goldfuss, i.e. the Heteropora dichotoma of 
de Blainville, Homer, von Hagenow, Drescher, etc., is Sparsicavea dichotoma 
(cf. Vol. I. p. 393). The Heteropora dichotoma of von Reuss, 1847 (Foss. Polyp. 
Wien, Tertiarb. : Naturw. Abh. vol. ii. p. 35, pi. v. fig. 20), of the Austrian 
Leithakalk, has double rows of mesopores between the apertures.
