appear to divaricate about once to seven or eight fenestrules, and 

 bear a very much elevated, blade-like keel v^ithin. The fenestrules 

 are long flattened ovals, about 6 to 10 mm. in length and 13 to 

 10 mm. across. There are four or five cells to a fenestrule. 



This probably belongs to the species figured by Phillips as 

 F. antiqua, var. a, from Lynton ; but it also comes extremely close 

 to the Hope's Nose fossil, which I have referred to his F. arthritica, 

 differing from it in probably branching more rapidly and in 

 certainly having the cell-mouths and keel on the outside face, 



Hallia quadeipartita, Freeh. 



1886. Hallia quadripartita, Freeh: Palseont. Abhandl., vol. iii, pt. 3, p. 83, 

 pi. viii, figs. 20, 21. 



Simple, cornute, oval in section ; axis excentric. Cup deep. 

 Major septa 28. Septal fossula deep, extending to centre and 

 containing the principal septum, which does not reach the centre. 

 Opposed and lateral septa reaching centre. Septa of each principal 

 quadrant 5, pinnate against the septal fossula ; and those of each 

 opposed quadrant 7, pinnate against its lateral septum,, Minor 

 septa 28, long. 



Size : about 23 mm. wide. 



There is one specimen from this locality, but the above description 

 has been completed from an example from near " Walls Hill," 

 which is in better preservation and contains forty-six septa. It 

 seems perfectly to correspond with Freeh's German species. 



Lower? Stringocephalus Beds of Gerolstein. 



Amplexus, sp. 



Conical. Cup very deep (about 25 mm. deep by 25 mm. wide), 

 flattened at the base. Major septa 28, reaching half-way to the 

 centre. Minor septa rudimentary. Tabulse (as seen at the base of 

 the cup) irregularly flat, extending to the sides, and marginally 

 deflexed. Septal fossula very deep, marginal, not extending half- 

 way to the centre, and containing a short septum, while the adjoining 

 septa arch round its sides. No dissepiments. 



The specimen, being only the distorted cast of the cup, is not easy 

 to decipher, but belongs, I think, clearly to this genus. As far 

 as can be seen, it approaches somewhat nearly to the Carboniferous 

 A. cornu-bovis, Edwards & Haime, 



Metriophyllum Elsii, n.sp. 



Small, apparently elongate, sub-conical, about 10 mm. wide. 

 Major septa 16, reaching to the centre, where they are slightly 

 deflexed. Minor septa 16, long. Signs of a large pseudo-columella, 

 which appears to be formed by the invagination of the centre of the 

 arching tabulas. 



This form seems the commonest true coral of the zone, though 

 rather rare. It is so similar in style and structure to Metriophylhim 

 gracile, Schliiter, that it is doubtless congeneric ; but it differs 

 from it specifically in the central twisting of the septa, the probably 

 looser structure of the columella, and other points.
