Alveolites Lahechei^ Salter, 1859, in Murchison’s Siluria, p. 532, pi. 40, fig. 8 , 8 d, 80 {cmt. 
excl., non Milne Edwards and J. Haime). 
This species is very variable in form. The surface is often gil)bons or 
maminillated ; calices sloped, margins thin, slightly unequal, generally some- 
what lozenge-shaped ; they are about a millimetre in diameter. 
Note. — The only specimen of this species sent to me shows the 
impression only of a pretty well developed individual. The specific characters 
I have just mentioned are easily seen in it, so that I have little doubt as to 
the identity of the specimen. 
Horizon and Locality. — In England in the Dudley limestone, and in 
Australia in a compact argillaceous rock, schistose and of ochreous colour at 
Bock Elat Creek, to the east of Monaro. 
2. Monticulipoea pulciiella, Milne Edwards and J. Haime.

Monticulipora pulciiella, Idem, 1852, Mon. Brit. Foss. Corals, p. 2G7, pi. 52, fig. 5. 
Coral ramose, branches often compressed, long diameter varying from 
five to ten millimetres. The calices are small, unequal, and usually sub- 
hexagonal in form. 
Horizon and Locality. — This species, which occurs in the Silurian 
limestone of Dudley and Wenlock, has been found in a specimen of greyish, 
very compact limestone from the banks of the Bell Biver,
