The colony i.s narrow and generally dichotoine, tlic branches licing of nearly 
equal thickness throughout, composed of alternating series of tubular cells, with the 
orifices bent outwards on cacb side. In well preserved specimens, which have the cells 
nearly perfect, the orifices arc rather distant, and their alternating position is toler- 
ably well marked, {see fig. 8), but when the surface becomes worn off, this 
regularity is less conspicuous, the cells appear to bo shorter, and the orifices 
arc sometimes placed nearly side by side. The alternating regularity is also less 
observable on sharply bent portions of the colony, or at the terminations of single 
branches. 
On the whole, there is, however, no essential distinction between European and 
Indian specimens. 
Locality. — North of Poodoopolliam ; found creeping on Terebratula sub- 
depr essa, rare. 
Fo) -ma t ion. — Arrialoor group . 
D’Orbigny described his specimen from ‘Mans (Sarthe)’, found in beds 
believed by him to be referable to Cenomanien, or the Craie chloritee.

Fid. colonia rainnlosa, ramidls graeilibus, sub-cylindricis, cellulis tubulosis in

superficie longitudinaliter lineatis ; orificiis plus minusve tubulose proficientibus atque 
lateraliter curmtis. 
The branches arc in this species thin, and almost roimd and cylindrical, being 
sli'ditly widened only near the orifices. The cells arc moderately elongate, in four 
or five altcriiatiug series, smooth, with opaque longitudinal lines. In ivcll preserved 
specimens the orifices are distinctly tubular and bent outwards, but the margins are 
easily broken away, and then the form of the apertures changes from round to an 
oval shape.
