COEALS OF THE LIAS OE EN GLAND AND S. WALES. 189 



many hundreds have been collected. During one visit there I picked 

 up more than two hundred specimens. The coral-bed at this place is 

 from one to two feet thick ; but its precise position in relation to the 

 coral-beds of Hon eybourn,AstonMagna, Hill Morton, and Cheltenham 

 I have failed to ascertain. The coral is associated with Terebratula 

 numismalis, Pecten priscus, Gryphcea obliquata, Ammonites armatus 

 (young), and A. Jamesoni. The presence of the latter in the coral- 

 bed, where it was found by my friend Mr. Beesley, of Banbury, 

 removes the MontlivaUia mucronata from the Lower to the Middle 

 Lias. Yet Mr. G. E. Gavey found this species and MontlivaUia 

 rugosa together at Aston Magna; and I think there is no doubt that 

 both occur at Fenny Compton. Besides these localities, I am able 

 to add Kilsby, in Northamptonshire, near Bredon, Gloucestershire, 

 Blockley Station, on the Oxford, Worcester, and Wolverhampton 

 Railway in Worcestershire ; and a specimen in the British Museum 

 is labelled Kettering.

 No. 2, pi. xiv. figs. 12, 13. 



Occurs with the last species at Fenny Compton, and is rare. 



Montlivaltia eaeiata, Duncan, Supp. Brit. Foss. Cor. pt. iv. No. 2, 

 p. 61, pi. xv. figs. 1-5. 



With MontlivaUia mucronata at Fenny Compton, rare. 



Montlivaltia Victoblze, Duncan, Supp. Brit. Foss. Cor, pt. iv. No. 

 2, p. 63, pi. xvii. figs. 1-10. 



The first examples of this fine species were obtained at Cherrington, 

 near Shipston-on-Stour by the late Mr. Richard Lamley, of 

 Tredington, near that place. Others have subsequently been met 

 with in abundance by Mr. Beesley in the Middle Lias near Banbury, 

 where they were associated with Ammonites ibex. 



I have now to add another locality, viz. Charmouth, three 

 examples having been found in the tumbled masses of Middle Lias 

 on the beach ; but their position in the cliff section has not been 

 ascertained. 



Fam. Fttngid^:. 



The species which I have now to describe was taken by me 

 from a large mass of tumbled Middle Lias on the beach under 

 the cliff at Charmouth, a little eastward of the spot where the 

 beautiful examples of Oplvioderma Egertoni are found. On the 

 same surface of the block, and in near proximity to each other, 

 were the following fossils — Plicatula sjpinosa,Rhynchonella tetraliedra, 

 a well-preserved and typical example of Ammonites margaritaftis, 

 a fragment of a MontlivaUia with thick septa, and the present 

 species. The presence of the above Ammonite would alone be con- 

 clusive evidence ihat it is a genuine Middle-Lias species. I believe 

 that it represents a new genus, and describe it as follows : —
