GRAPTOLITES OF AUSTRALIA 
45 
In some critical remarks on the flora and fauna, he states : 
‘ Graptoloidea have been reported on by the late Dr. T. S. 
Hall. Some of the forms are rather high in the series, as 
compared elsewhere, and on account of their indifferent 
preservation, may require revision. Besides the first three 
on the list, determined by Dr. Hall, I have found the predomi- 
nant graptolite supposed to belong to the Walhalla plant- 
bearing beds, to be a form related to Monograptus cf. jaeheli 
Perner, of the M, priodon type. Dr. T. S. Hall’s plesiotypes 
of M. duhitis, which have been examined by Mr. W. J. Harris 
and myself, belong to a form of the M. priodon type.” 
1925. — R. A. Keble (101) recorded from Allot. 28, Parish 
of Langwarrin Climacograptns sp., probably of Upper Ordo- 
vician age; from the Howe’s Creek Phosphate Mine, in a 
trench on Allot. 113a, Parish of Loyola, Monograptus lepto- 
theca, M. rncCoyi, M. cf. cutellus, M. cf. proteus, M. spp. nov., 
Climacograptus sp., Diplograptus sp., and Retiograptus sp. 
He regarded the age as equivalent to the Llandovery of 
Britain. 
From a locality north of Greendale he recorded Didymo- 
graptus aureus, Tetragraptus fruticosus (4 and 3 branched), 
T. hryonoides, T. cf. quadrihracliiatus, T. cf. acclinans, Biclw- 
graptus octohrachiatus, and Goniograptus laxus. 
From the Lerderderg River, between the river and the 
headwaters of Rum Creek, Parish of Blackwood, he recorded 
Didymograptus aureus, 1). latens, D. extensus, Tetragraptus 
fruticosus (4 branched), T. pendens, T. decipiens, T. Jiarti, T. 
serra and Fhyllograptus angustifolius. 
R. A. Keble and W. J. Harris (102) recorded a number 
of species from Mt. Easton (incorrectly referred to as 
Eastern). Diplograptus calcaratus var. vulgatus and Lepto- 
graptus capillaris were recorded for the first time in Victoria. 
They described and figured Climacograptus missilis sp. nov., 
C. exiguus sp. nov., Leptograptus faccidus var, subjectus 
nov., L. eastonensis sp. nov. and Dicellograptus gravis sp. 
nov. They show in a table the relative position of the Mt. 
Easton beds in relation to the British Zones, 
W. Baragwanath (104) adojited the following provisional 
classification of the Silurian in the Aberfeldy District: 
Upper Silurian 
Walhalla Series. 
Jordan River (and Donnelly’s Creek) beds. 
Lower Silurian 
Mt. Useful beds.
