the age could be between basal Lower Devonian and basal Middle 
Devonian, as determined from the coral evidence. 
In the present study, it is noted that the Loronema australis 
from Sandy’s Creek cannot be distinguished from the type speci- 
men which came from the Lilydale limestone, nor Tancrediopsis 
raricostae from the type specimen collected from beds of Yer- 
ingian age at Killara. Protoleptostrophia affinalata cannot be 
specifically distinguished from specimens which occur in beds 
among the highest in the Lilydale sequence, viz., at Hull Rd., 
Mooroolbark. The Eospirifer, Protoleptostrophia, Hipparionyz, 
and Chonetes from Sandy’s Creek are comparable with forms 
found in the Upper Yeringian shales and sandstones at Lilydale 
(vide Gill, 1945a), but are more advanced, and therefore probably 
slightly younger. Immediately above and slightly younger than 
the shales and sandstones at Lilydale is the Lilydale limestone, 
which is generally regarded as belonging to the upper end of the 
Lower Devonian, although Hill (1939, 1943) considers a Middle 
Devonian age possible. The Sandy’s Creek beds containing the 
fossils deseribed in this paper are probably comparable in age 
with the Lilydale limestone, but cannot be placed in the Middle 
Devonian because of the presence of the genera Hospirifer and 
Hipparionyx, which do not extend beyond the Lower Devonian. 
On present knowledge, therefore, the age of the Sandy’s Creek 
beds referred to in this paper is considered to be the top of the 
Lower Devonian, i.e., Coblenzian. 
A curious element in the fauna is Carimiferella, a genus of 
Upper Devonian age in North America and Europe. However, 
this genus has been erected comparatively recently, so that its 
range and relationships are not well known. It is herein recorded 
from Australia for the first time.

Acanthoclema flexuosa Chapman, Ree. Geol. Surv. Vic., Vol. IV, Pt. 2, 1920, p. 
189. Pl. XXIV, Fig. 20; Pl. XXXII, Figs. 38-40. 
A branching polyzoan from locality G22 (specimens 27,207, 
27,208 and 27,211) apparently belongs to Chapman’s Acantho- 
clema flexuosa, described from the Gibbo River, N.E. Gippsland, 
and regarded as Yeringian in age. The holotype of this species is 
housed in the National Museum, and is Reg. No. 15,964.
