A single fragment of a compressed brancli indicates that the stem of this 
species must have been rather broadly foliaceous. The cells arc elongate, moderately 
elevated, with the upper surface flattened and the sides all round slanting; the 
former is along the lateral and lower margins provided with a continuous series of 
eleven transversely elongated pores. These pores begin a short distance from the 
straight lower lip of the apertui-e, which latter is enthely anterior and of a semi- 
elliptical shape. On each side of the upper lip lies a tumid, rounded aidcularium, 
possessing a small rounded opening. 
The species is evidently closely allied to incrassata, (d’Orhigny), (Pal. 
fran9. terr. cret., v, pi. G85, figs, l-d), which differs in having the pores more numer- 
ous and extending up to the edge of the lower lip, and also l)y ha via g the avicularia 
placed above, instead of at the side of the aperture. 
Locality. — Chokonadapooram, in a pinkish sandy limestone.

This is most closely allied to E. vicinalis, described by Von Hagenow from the 
Maastricht beds (Bryoz. dcr Maastricht. Krcidcbildung, See., 1851, p. 63, pi. vii, 
fig. 6). The peculiarity of this sj)ecies consists, however, in the presence of a slit- 
like opening at the base of each cell, or rather the pore is placed in the centre between 
each fom* cells, and is narrowly prolonged on to the surface of the succeeding cell 
above it. In place of tliis slit-like opening, there are in the present species two small 
pores on the surface of each cell, placed one below the other, but none at the base 
of the cell itself. Besides there are generally six pores round the aperture, the 
one, placed a short distance below the lower lip, being usually conspicuously larger
