48 BRITISH FOSSIL CORALS. 
dale sp.; B. Bairdiana, Hd. and H.; B. geniculata, D’Archiac; B. Cumingit, Ed. and H., 
and B. subcylindrica, Philippi sp., may be arranged together to form a subgenus charac- 
terised by forms with broad adherent bases. The following species will fall into another 
subgenus whose forms have the base more or less pedicillate :—Balanophyllia prelonga, 
Michelotti, sp. ; B. Gravesii, Michelin, sp.; B. senuata, Reuss; B. inequidens, Reuss ; 
B. fascicularis, Reuss, and B. Australiensis, Duncan. 
The new species from Brockenhurst, B. granulata, must be received into the first sub- 
genus. ‘The absence of epitheca, the profusely granular coste, and the existence of part 
of the sixth cycle of septa, distinguish B. granulata from all the species already described. 
‘There is nothing in the species B. granulata to connect it with any geological horizon ; 
for the Balanophylie without epitheca range from the Eocene to the present day. 
The species B. granulata has only a generic alliance with those described by Reuss, 
Roemer, and Philippi. 
Genus—LOBOPSAMMIA. 4 
LoporsaMMIA CARIOSA, Goldfuss, sp. Plate VII, figs. 6—10. 
The corallum has a wide base, above which it is slightly constricted. It rises im the 
form of a short cylindrical trunk, terminated by several gibbous processes, which support 
calices and project outwards. 
The under surface of the base has a concavity’ which is lined and surrounded for a 
short distance by a dense epitheca; the coste radiate around the margin of the epitheca, 
and ascend the outside surface of the corallum, pursuing very irregular and wavy courses, 
being thin, rounded, equal, and joined laterally by numerous cross bars of exotheca. 
The costa, which are very faintly granular, have this same peculiarity’ on the upper 
surface of the corallum between the gibbous calices. 
The calices are irregular in shape, and so speedily commence to elongate prior to 
dividing fissiparously, that simple ones are rarely seen. They are, nevertheless, in the 
figure of eight, and are situated on the ends of the gibbous projections ; their margins are 
irregular, the fossa is shallow, and the columella is very feebly developed. 
The septa are very numerous, and form at least five cycles in six systems; they are 
unequal, stout, and often bifurcate near the columella. 
Height of corallum about one inch; diameter of trunk 2ths inch; greatest diameter 
of calices “ths inch.
