genus, though I do not wish to he positive on the last point, as I had no oppor- 
tunity of examining any of the typieal speeimens figured liy d’Orbigny. Of the 
other genera recorded in the family, d’Orbigny’ s Flaniccllaria and Fusicellaria 
appear to be fairly separable from ScUicornaria, although very closely allied to it. 
NelUa, Busk, and Foricellana, d’Orb., I do not know at all. What Sars called 
Qaadricellaria stands in somewhat similar relation to Cellaria, as does d’Orbigny’ s 
genus of the same name to SulicornaHa, the form of the colonies and position of 
the cells being in both similar, Imt the branches are not articulated, and therefore 
Sars’ genus must be denoted by another name. (Comp. Quart. Jour. Micros. Sc., 
186I-, p. 101). Palmicellaria of Alder (Quart. J. Micros. Sc., IV, 18G1, p. 100,) 
might also from its name be thought to belong to this family, but as the colony is 
inarticulate, and as the branches do not show ‘ even a sign of contraction at their 
bases,’ the genus must be referred to the Cullepohidm, unless it be found desirable to 
separate into a distinct family the recent forms of the type of the two last genera, 
and of which there are also a few fossil species described under Viueularia and others. 
Of the CiiLLAiiiiD/B, as here understood, there are two genera represented in the 
South Indian cretaceous deposits, each by a single species. 
Salicornaria, Cuv., 1817. 
Colony ramose, composed of flustrine cells round an imaginary axis of cylin- 
drical branches, which are connected with each other by horny filaments ; the joints 
are always attenuated at their base, and in adult colonies sometimes permanently 
anebylosed. Each cell is usually provided with an avicularian opening above the 
aperture, which is sub-anterior or sub-central. 
Species of Salico^'uaria occur from the cretaceous period up to the present time. 
Planicellarki, d’Orbigny, 1850. 
Colonies ramose, dichotome, branches articulated, slightly compressed, with 
two alternate series of flustrine, strongly margined cells on the two opposite broader 
sides, and an undulating series of small, tumid avicularian cells on each of the 
nai’i’ower sides. 
There appears to be only a single cretaceous species of this genus known, as will 
presently be noticed in more detail.

The single joints appear to be rather short, each is attenuated towards the base, 
and at the termination perforated, having evidently been attached by a flexible
