Lnn. colonia cupuliformi; cellulis (piadrangularibiis, longituclinaliter conjlu- 
pntibns, movginibus nndiqiie sed precipue in parte anteriore elevatis ; apertura 
siib-antica, spaciosa, immersa, siibquadrangulari ; labio fere recto; seriebns amcu- 
larioriim tertiam partem latitudinis celhdarum cequantibus, orificiis elongate ovatis. 
Tlie colony is regularly cupnlilbrm, with the cells equally regularly disposed 
ill radiating as well as in concentric series, and as the anterior margin of each cell 
is considerably more elevated than the posterior one, the whole colony has the 
appearance of heing composed of rings, successively increasing in diameter, like 
the steps of an amphitheatre. The aperture is snhquadrangular, placed anteriorly, 
and the upper elevated margin often slightly oyerhangs it ; its lower edge is nearly 
straight. The avicularia lie in depressions, which have only one-third the width 
of the regular colls, and are provided with elongately ovate apertures. 
In colonics with an imperfectly well preserved surface the margins become 
more or less easily ivorn olT, and the orifices of the cells larger and of a rounded or 
oval shape.

[Cellahidte, d’Orb. et auct. Salicornariid^, Busk, et aucl.). 
The genera belonging to this famUy are chiejly characterized by the articulated, 
cylindrical or moderately compressed, branched stems, the single branches being 
joined, to each other by fibrous, most qmobably chitinous or horny strings, ^lsually 
terminating pointedly at the base and truncate at the anterior upper end. The cells 
are disposed all round the stem, or on two opposite sides, and are either of the 
urceolate or fiustrine shape, xcith or without ovicells, or vibracula. 
According to this marked ditference in the form of the cells the family may be 
divided into two sections, the former being represented by the true Cellaricc (type C. 
opuntioides or C. cereoidesj, fiwCi the latter by Salicornaria of Cuvier, (type S.far- 
ciminoides, 3 olinst). I have elsewhere* discussed in great detail the relation of 
these two genera, which by most authors had been Avrongly considered as identical with 
each other ; but while separating these two typical forms, I have attempted to prove 
that Glauconome of Munster is the same as Saticornaria, and that, on the other 
hand, 3Iargaretta, Gray, Tubucellaria, d’Orb., and Onchopora, Busk, cannot 
be maintained as distinct genera from Cellaria. The species which were originally 
dcscribed and figured by d’Orbigny under the name of Cellaria in Vol. V, 
Pal. franc, terr. cret., are unquestionably to be reterred to SaUcornaria, and 
those described as Quadricellaria are probably also not distinct from the latter
