716 R. F. TOMES ON THE OOLITIC 
Species from the Coral Rag. 
Genus Sryzina, M.-Edw. & Haime. 
STYLINA, sp. 
A species which is represented by a single worn specimen apper- 
taining to the decameral type of M. de Fromentel, appears in the 
collection. 
The calices are rather crowded, and have a diameter of one line, 
with rather thick and prominent margins. There are ten principal 
septa, which are of one length, and closely approach the columella. 
The remainder, ten in number, are very short. The columella is a 
little compressed. The intercalicular coste are, so far as may be 
ascertained in the worn specimen, of nearly equal size. 
I have compared this coral with Styline from our own Coral 
Rag, and from presumably corresponding horizons at Nattheim and 
in the Haute-Sadne, but fail to identify it with either species; nor can 
I refer it to any of those which have been described by MM. Milne- 
Edwards and Haime, MM. de Fromentel, Milaschewitsch, and others. 
It appears to come nearer to Stylina constricta and S. bullata of 
M. de Fromentel than to any others. 
The specimen mentioned was obtained from the Coral Rag of 
Hourecq. 
STYLIN, sp. 
Another worn specimen, specifically distinct from the foregoing, 
has calices which are not crowded, and which have a diameter of two 
lines. There are six primary septa, which closely approach the colu- 
mella and end in a paliform enlargement, which is equal in size to 
the somewhat compressed columella. Six secondary septa are one 
third the length of the primary ones, and have no terminal enlarge- 
ment. Those of the third cycle are half the length of the second. 
Neither the prominence of the calices nor the intercalicular coste 
are observable from the worn condition of the specimen. 
It was taken from the Coral Rag at Questrecques, at a somewhat 
higher geological level than the last-mentioned species, from which 
it is obviously distinct.

Several clusters of broken corallites in parallel masses, having 
very equal non-papillated but granulated mural cost, and frequently 
recurring and strongly developed annular expansions, occur in the 
collection. These, in the size of the corallites and in the equal 
development of the coste, as well as in the particulars above stated,
