1. Anveouires Lasecurr. Tab. LXI, figs. 6, 6a, 64. 
FAVOsITES SPONGITES (pars), Lonsdale, in Murchison, Silur. Syst., pl. xv bis, figs. 8, 8a, 86 
(czet. excl.), 1839. (Not Calamopora spongites, Goldfuss.) 
CaLAMOPORA sPoNGITES, Hichwald, Sil. Syst. in Esthland, p. 197, 1840. 
Atveouitrs Lasncui, Milne Edwards and Jules Haime, Pol. Foss. des Terr. Paleeoz. (Arch. 
du Mus., vol. v), p. 257, 1851. 
Corallum massive, convex or subgibbose, very closely resembling the <Alveolites 
suborbicularis' of the Devonian formation ; but differing from it, by the calices being more 
regular, scarcely prominent, with very thin edges, and subtriangular, and by the inner 
process being very indistinct. Large diameter somewhat more than one third of a line; 
small diameter one third less. 
Found in the upper Silurian deposits at Wenlock, and at Benthall Edge. Professor 
M‘Coy* mentions its existence at Doonquin, Dingle, and Ferriter’s Cove, in the county 
of Kerry; Egool and Bellaghaderreen, in the county of Mayo; River Chapel and Gorey, 
in the county of Wexford. According to Hichwald, it exists also in Russia. 
Specimens are in the Collections of the Museum of Practical Geology of London, of 
the Parisian Museum, of M. Bouchard-Chantereaux at Boulogne. 
2. Atveotites Grayi. Tab. LXI, figs. 2, 2a. 
ALVEOLITES GRayt, Milne Edwards and Jules Haime, Pol. Foss. des Terr. Paleeoz. (Arch. 
du Mus., vol. v), p. 258, 1851. 
Corallum presenting a flat or submamillose surface. Cadices very irregular, inclined 
in various directions, in general subtriangular, and having their outer margin somewhat 
arched. The elevation situated on the inner surface of this inferior calicinal edge in 
general distinct, but not very prominent. Walls rather thick. Size of the calices: large 
diameter about half a line, small diameter one third less. 
Upper Silurian rocks of Wenlock and Dudley. Specimens in the Collections of the 
Museum of Practical Geology, of Mr. J. Gray of Dudley, and of the Museum of Paris. 
This species much resembles Alveolites suborbicularis’ and A. Labechei,* but its calices 
are always larger, and limited by walls that are thicker in proportion to the size of the 
corallites.
