limestone, also at Limokilns [Limekilns] in a greyish limestone. It is -widely 
distributed in the Devonian of Belgium, Prance, England, Germany, Russia, 
and America.

Corallum a rounded mass, sometimes of very considerable size. 
Corallites rather long, radiating, suhequal, often taking the form of a 
hexagonal prism. Mural pores almost always forming a single series in the 
middle of each wall and a millimetre apart. With the exception of the 
upper, on which may he distinguished usually four small depressions, the 
tabulae are flat, smooth, and about a millimetre apart. 
Horizon and Localities. — This coral has been found in the Devonian 
of Nehou, of the Eifel, and of the United States. Mr. Clarke has collected 
it in a greyish limestone at Shoalhaven Gullies and at Calalamine. 
3. Pavosites alveolabis, Goldfuss.

Favosites ,, Blainville, 1831, Diet. Sc. Nat., LX, p. 367. 
,, ,, Milne Edwards and J. Haime, 1851, Polyp. Foss. Terr. Pal., p. 234. 
Corallum rather massive, calices relatively large but rather unequal. 
The tabulae have near the wall four small shallow depressions ; they are 
arranged horizontally and regularly spaced. The mural pores are rather close 
and occupy the angles of the visceral chamber. 
Himensions. — Diameter of large calices about three millimetres. 
Horizon and Localities. — A single specimen of this species has been 
found at Calalamine. It occurs in the Devonian of Perques, the Eifel, and 
North America.
