In the corner of Case G are specimens of Calceola sundalina 
better shown in the Eifel series; this is allied to Mizo- 
phyllum, and, from its triangular shape and large lid, 
closely resembles some brachiopods (Fig. 23).

and I), the outside of the operculum ; c and d, corresponding views of 
the calyx ; e, a specimen with the operculum closed over the calj’x.

The Carboniferous corals are the last of the Palaeozoic 
type. 'J’he foreign collection inchides specimens from Arctic 
America, from Tonrnai and Vise in Belgium, and several 
brouglit from the Ural Mountains by Sir Boderick Murcbison. 
Among the Briti.sh Favositidae are the curious little 7V</nrac/.s' 
and a good series of SyrinyojJOi'a. Close by is ^fonUnpora 
crassa growing on crinoid stems, which become deformed in 
the attempt to grow over it. Chcwfctes, which follows, is 
referred with doubt to the Alcyonaria. On the other side of 
the Case come Amplcnis and Zcqdirenfis, showing marked 
bilateral symmetry in the arrangement of their septa, such 
as obtains in the mesenteries of the recent Zoanthidae, which 
have no skeleton. In Amplcxus the septa are reduced in 
size, but tabulae are strongly develo])ed. There follow 
several genera of Madreporaria Aporosa : the cylindrical 
Campopliyllum, which may grow to a great length, as shown 
by specimens from Weston-super-Mare ; Lonsdaleia and 
Lithostrofion, whose prismatic tubes build up large colonial 
masses, as those of the familiar Lithostrotion based tifor'fnc 
and of L. irreynlarc from Fermanagh ; Dihunophyllum, of 
stratigraphical importance, shown also on a fine slab from
