128 BRITISH FOSSIL CORALS. 
Family ASTREID A, (p. xxii.) 
Genus AXOSMILIA, (Pp. XXVi.) 
Axosminia Wricati. Tab. XXVII, fig. 6. 
Corallum simple, having the form of a very elongated cone, very narrow at its under 
end, straight or but slightly curved, presenting circular accretion swellings, and covered 
with an epitheca which appears to extend to the calicular edge. Calice circular. Septa 
forming four complete cycla; straight, thin towards the centre of the calice, appearing to be 
delicately granulose laterally, unequal in size according to their relative age, and not closely 
set. Height of the corallum about one inch. Diameter of the calice four or five lines. 
Found at Dundry and at Cheltenham, in the Trigonia beds, by Dr. Wright. 
It is not without much uncertainty that we refer this oolitic coral to our genus 
Axosmilia, for in all the specimens which we have seen, the calice was so imbedded in the 
stone, that we have not been able to observe its most essential characters, such as the 
styliform columella; by the form of the septa we may infer that their edge was entire, and 
the calice deep, as in Awosmilia, which this fossil resembles also by its general aspect, more 
than it does Montlivaltia ; but if the presumed characters do not in reality exist, it may 
belong to the latter genus. At all events 4. Wrighti differs from Azosmilia extinctorum,! 
and from 4. multiradiata’ by the number of the septa, and the equal development of all 
the septal systems, for in 4. multiradiata there are five cycla, and in A. extinctorum only 
three complete ones, and the septa of the fourth cyclum exist only in one half of each 
system. 
Genus STYLINA, (p. XX1X.) 
STYLina sotipa. (See page 105, and Tab, XXII, fig. 3.) 
This fossil, which is met' with in the Inferior Oolite near Bath, is also found in 
the Great Oolite, and has consequently been described in a preceding chapter of this 
Monograph.
