136 BRITISH FOSSIL CORALS. 
from the above-described fossil; and we must only add, that most of them have been 
mentioned by M. D’Orbigny, under the generic denominations of Amblophyllia and 
Lasmophyllia.* 
Genus LATOMEANDRA, (Pp. XXXIV.) 
1. Latomeanpra Firminer. Tab. XXVII, figs. 9, 9a. 
Corallum composite, massive, rather tall; its upper surface horizontal, or slightly 
convex, and presenting large deep calices, which are sometimes completely circumscribed, 
but are in general confluent in one direction, so as to form furrows of unequal length, but 
rarely long. ‘The mural ridges situated between these furrows are always simple, not much 
elevated, and terminated by a well-defined edge, which, when slightly worn down, shows 
very distinctly the walls themselves. The ca/ices are rather deep, especially in the adult 
corallites, and the young individuals are formed at a considerable distance from the centre of 
the visceral chamber of the parent. The sep/a are very thin, closely set, narrow towards the 
top, delicately crenulated along their edge, straight or slightly curved, and unequal in size 
alternately ; in the larger calices there are about sixty of these radiate lamin; they 
become almost parallel in the furrows; but even there the different corallites are in general 
distinct, and have each a separate fossula. Diameter of the calices, or breadth of the 
furrows in general, 4 lines; depth, 2 lines. 
Found in the Inferior Oolite at Crickley, near Cheltenham, by Dr. Wright. 
We are inclined to think that the fossil coral mentioned by Mr. Conybeare and 
Mr. W. Phillips,* as bemg intermediate between Astrea and Meandrina, and as having 
been found in the Inferior Oolite, may belong to this species. 
The genus Latomeandra was established a few years ago by M. D’Orbigny,* but that 
paleeontologist restricted the group to those species which assume a somewhat dendroid 
form, and constitute series which remain free laterally ; those which have the same structure, 
but are of a massive form, are referred to our genus Ou/ophyllia, or to three new generical divi- 
sions which he designates under the names of Avophyllia, Microphyllia, and Comophyllia, but 
which do not appear to be founded on characters of sufficient value. The specimen from which 
the definition of the genus Avophyllia was taken presents, in some calices, the appearance 
of a styhiform columella, but that is due to an accident of fossilization, and is produced by 
the presence of a small calcareous concretion in the fossula. In the genus Comophyllia the 
calices appear to be very shallow, a peculiarity of small importance, and in the genus
