Ohs. A single fragment of au Amplexus from the Broken Eiver Limestone has 
some relation to A. Selwyni, De Koninck, hut it is very much smaller and possesses only 
half the number of septa. There is no trace of a septal fossula at all, and in all proba- 
bility the epltheca was very thin. There are about thirty septa, and the cost® are 
regular and very apparent, whilst the central tabular space is large for the size of the 
corallum. Although the specimen is only a fragment, the corallum was evidently 
cylindrical and somewhat curved. 
Loo. Broken Eiver, a tributary of the Clarke Eiver. (JB. L. JacTc.) 
Genus — OAMPOPILYLLUM, Edwards and Haime, 1850. 
(Mon. Brit. Foss. Corals, Ft. 1, p. Ixviii.) 
CAMPornxLLTTM Gteegoeii, sp. nov., PI. 3, figs. 15-18. 
Sp. Char . Corallum long, either straight or gently curved, and sometimes 
slightly twisted. Epitheca apparently thin, and with indistinct growth accretions. Septa 
numerous, sixty at least, gradually tapering at the extremities; secondary septa less than 
half the length of the primary, and much more slender. Vesicular tissue forming a 
zone having a width about equal to the length of the secondary septa, the vesicles small 
and close together. Septal fossula large, containing one primary septum (or some- 
times two ?) Central tabulate area conspicuous, almost equal in breadth to the length 
of the primary septa. Tabul® horizontal, or sometimes slightly oblique and very close 
to one another, in places almost touching. 
Ohs. The genus Oampophyllum has not been extensively recognised as Devonian, 
but investigation will probably prove it to have flourished at that period to a greater 
extent than has been supposed. Prof. L. Gr. De Koninck has recorded the occurrence 
of Campophjllumflexuosum, Ed. and II., in the Lower Devonian Series of Quadong, 
N. S. Wales, but I believe this is the only species yet recognised in Australia. The 
present coral is quite distinct from the latter, and I feel much pleasure in associating 
with it the name of the Hon. A. C. G-regory, who has for so many years been connected 
with Australian science and exploration. 
Loc. Eegan’s, Benwell’s, and Philp’s, Northern Eailway. (12. L. Jack.') 
Order— ALCYONARIA. 
Family— HELIOLITID^. 
Genus— IIELIOLITES, Eana, 1846. 
(Zoophytes, Wilkes U. S. Expl. Exped., p. 541.) 
Ohs. The Silurian and Devonian rocks of one or other of the Australian 
Colonies have yielded six species of this genus, so far as present researches have gone, 
and to these we have to add a seventh and eighth. 
Heliolites inter stinctus, Linn., has been met with; according to Prof. McCoy,* 
in the Upper Silurian Limestone of Waratah Bay, Victoria. The researches of Prof. 
De Koninck have shown the existence of K. megastoma, McCoy, and S. Murchisoni, in
