crossed by numerous folds or rings of growth. Lonsdale says the septa arc 
numerous, and his figure indicates alternating rudimentary septa. The tabulae 
seem to be covered with small protuberances, and the fossula is not well 
developed. In these two last characteristics it resembles Zaphrentis 
cylindrica, Scouler, and possibly it should be jfiaced in the same genus and 
next to it, but the specimens sent me are too imperfect to enable me to decide. 
'Formation and Localities. — Strzelecki found this species at Shoal- 
haven and Barbers, and Mr. McCoy at Curradullas, New South Wales. The 
specimens sent me by Mr. W. B. Clarke are chiefly external impressions, 
found abundantly at Colocolo in a yellowish -brown limestone of Carboniferous 
age. The age of the limestone is satisfactorily proved by the presence in it 
of Griffithides Elcliioaldi, Tischer, and of Cladoclionus brevicollis, McCoy. 
Genus — ZAPHBENTIS, Bafinesque and Clifford.

In spite of his immense experience in the classification of Carboniferous 
corals, my learned friend, Mr. J, Thomson, is unable to state with certainty 
the species of the small specimen he has kindly examined for me. It is too 
imperfect a specimen to be figured. He describes it thus : — “ Corallum 
small, in shape a bent cone, circular in section ; epitheca thick ; septa, 
numbering twenty-two, perfectly distinct, re-uniting in groups, and extending 
to the centre of the visceral cavity. The primary septa alternate with an 
equal number of secondary ones. The fossula reaches the centre, and is 
bounded by two primary septa, strongly bent in contrary directions, having 
their concavity turned away from the side of the fossula.” 
Eimensions. — The diameter of the fragment described is only about six 
millimetres, and is probably part of a young individual.

not FJtiU'ipsi. Vide Mem. Geol. Survey N. S. Wales, I’al. V, Tt. 1, 1891, p. 13. — W.S.D.]
