with the numerous buds. It is distinct from the Miocene 
species. 
7. Dasyphyllia , Spat 
~ Several specimens of a species of this genus, with collared 
eminences, are in the British Museum as well as in the Geol. 
Soe. Coll. 
8. Montlivaltia brevis, n. sp. Pl. XVIII. fig. 4. 
The corallum is short, and has a large base, which equals the 
calice in diameter. The calice is very nearly circular and very 
shallow. The septa are crowded, thin, and long; and there are 
five cycles of them, with occasional orders of a sixth ; the higher 
orders are small, and extend but a little way from the wall, while 
the larger septa meet nearly in the centre of the calicinal space. 
The septa are evidently not very exsert. The costz are distinct, 
parallel, and generally equal: close to the calice they appear to 
have been dentate; but elsewhere, the presence, and the evi- 
dences of the former existence, of an epitheca render them more 
or less indistinct. There are traces of an exotheca. Height of 
corallum -°;—=2, inch. Breadth of calice 2 inches.

This species is very closely allied to M. sessilis (Anthophyllum, 
Goldfuss), and less so to M. detrita. 
9. Antillia plana, n. sp. Pl. XVIII. fig. 5. 
The corallum is very short, and has a flat base, which equals 
the calice in diameter. The calice approaches somewhat the 
figure of 8, is stout at the margin, rather shallow, and presents 
a prominent circular parietal columella. The septa are crowded 
at the margin, but less so close to the columella ; the primary are 
the largest, being not much larger, however, than the secondary ; 
the tertiary are delicate, and reach, with those already noticed, to 
the columella. The higher orders of septa are small, and in 
some systems the highest are rudimentary. There are five cycles 
of septa, in six systems. The coste are of two kinds—one sub- 
equal and large, the other very small and only reaching a little 
distance from the calicular margin. The columella is lax, large, 
and occupies some space, being also nearly circular. The greatest 
depth of the calice is a little external to the columella. The 
epitheca is noticed here and there, but generally the distinct 
and rather prominent plain costz are uncovered by it. Height 
of coral ;8; to 4; inch. Width of the calice +2 inch; length of — 
the calice +5 inch.

The shape and large fixed base distinguish this species. It is — 
allied to A. ponderosa.
