Favosites basaltica, Goldf. var. moonbiensis, Etheridge, jun., 1899, Eec. 
Geol. Surv. N. S. Wales, vol. VI., p. 164, pi. XXIV., figs. 1, 2 ; pi. 
XXIX., fig. 2. 
Observations. —-This coral here occurs in a brecciated limestone grit, of a 
peculiar mottled colour, the white being dappled with pale pink and green. 
The fragmentary pieces of coral are well preserved, and on fractured and 
weathered faces show the mural pores disposed evenly in a single row along 
the length of each corallite or prismatic face. As in Etheridge’s specimens 
from Moonbi, N.E of Tamworth, N. S. Wales, the diameter of the individual 
corallites is uniformly I mm. An apparent discrepancy between the Victorian 
and New South Wales specimens, in regard to the spacing of the tabulse, as 
shown in the present photomicrograph (pi. XXIV., fig. 21), is explained by the 
fact that the tabulae vary in their spacing in different parts of the corallum, 
those near the base being crowded, as in Etheridge’s figured variety, whilst 
those near the peripheral layers are more widely spaced, as in Etheridge’s 
variety, salebrosa, of the same species.^ 
This variety occurs in the Tamworth series (Upper Middle Devonian) of 
New South Wales. 
L'Ccurrence. —•Limestone Creek, opposite the junction of Painter’s Creek

son, 1879, Tabulate Corals, p. 133, pi. VI., figs. 5, ba-b. 
Observations. —A mould of a small cylindrical and branching corallum 
of Coenites occurs in the Mitta Mitta series associated with Tryplasma and 
Conocardium. It compares very closely in every respect with Eichwald’s 
species, in the form of the calicular apertures, as well as in the general habit 
of the corallum. C. juni'perinus is a Silurian species in Great Britain (Dudley), 
Russia, and North America (Lockport). The genus Coenites has already 
been recorded from Victoria by Mr. R. Etheridge, jun.,^ who has noted an 
indeterminate species from Sandy’s Creek, Gippsland, which differs in habit 
from ours in having an encrusting corallum, and in this respect is compared 
by Mr. Etheridge with C. labrosus, Edw. and H., C. laminata, J. Hall sp., 
and C. lunulata, Nich. and Hinde. 
Occurrence. —Calcareous shales. Mitta Mitta River (No. 2550). Silurian 
(Yeringian).

pi. IX., fig. 4. 
Observations. —-This species is represented for the first time in Victoria, 
in the hardened blue mudstone of the Gibbo River, N.E. Gippsland. It 
occurs in association with other corals, as Tryplasma liliiformis, Eth. fil. 
The impressions of the calices and the regular straight alignment of the 
grouping to form the corallum, are very distinct. In New South Wales 
it is found in the Silurian of Spring Creek, Co. Ashburnham, and Molong. 
Occurrence. —Gibbo River (No. 2681). Silurian (Yeringian).
