Mr. Uhich places the genus Mitoclema, which he defines as below, 
in the Fam Entalophoridae, Reuss: "Zoarium ramose, slender. Cell 
mouths more or less prominent, and arranged in transverse series 
round the branches or irregularly spiral." (Op. cit., p. 150.) There 
is a difference in the American species, and because of the regularity 
of the spirals Mr. Waters suggests that it might probably be identi- 
cal with the Mesozoic Entalophora verticilata. Gold. 
13. Entalophora escharaforma (n. sp.? Provisional). PI. XII. 
figs. 21-22. 
There is present in the shales a very peculiar fossil, occasionall}' 
branching, sometimes flattened, which I place here provisionally. 
Fragments fit for diagnosis are rare. The cells are arranged in 
diagonal rows on the stem, having an eschara like character super- 
ficially, but in section the cells are regularly tubular: occasionally a 
colonial growth in a ribbon-like band covers the original colony, 
with a base similar to the band-like growths of species of Terebel- 
laria in the great Oolite. The cells in some of the examples are not 
altogether unlike, superficially, the Discopora favosa" of Lonsdale. 
Localities: Buildwas beds generally, occasionally in Tickwood 
bed. No. 42. 
Family Fenestellid^e (restricted.)
