DicJiograptus octohracMatus, Clonograptus abnormis and G. 
sp. 
.1913, — In 1903 J. W. Gregory^ divided the Silurian of 
Victoria into two series, viz.: the Melbournian and the 
Yeringian, and Chapman (71) added the Tanjilian. From 
the Melbournian Chapman (71) recorded Dendrograptus sp., 
Monogmptus cf. concinnus, M. cf. cy pirns, M, ef, dnhius, M. 
priodon; from the Yeringian, Cyrtograptus sp., Monograptus 
priodon, M. riccartonensis, and Retiolites australis; and from 
the Tanjilian ( ?) Cyrtograptus sp., Monograptus cf. crenu- 
latus and M. duhius. N. E. Junner (74) found Glimaco- 
graptus and Diplograptus in black, pyritic slates at the 
Diamond Creek Mine. 
1914.— W. E. Browne (75) gave a list (supplied to him by 
C. F. Laseron) of graptolites found by the latter in Wam- 
brook Creek, near Cooma, New South Wales. The list is 
more detailed than that previously given (66) and comprises 
Diplograptus foliaceus (very abundant), Climacograptus 
hicornis, C. liastata (very abundant). Dicell ograptus elegans, 
D. caduceus, D. affinis and C?) Pleurograptus. He stated 
that Tetragraptus, Didymograptus and Diplograptus occur 
in slates at Gcygedzerick Hill, 2| miles north-east of Berrie- 
dale, indicating the existence of the higher series of the Lower 
Ordovician in New South Wales. He also mentioned that C. 
F. Laseron had found in the neighbourhood of Cobargo, about 
44 miles a little south of east of Cooma, Diplograptus folia- 
ceus, Climacograptus, Dicellograptus ( ?) gracilis and D. 
affinis. 
”T. S. Hall (76) described and figured Didymograptus ex- 
tensus, D. perditus sp. nov., D. gracilis, D. aureus sp. nov., D, 
latens sp. nov., D. procumhens sp. nov., D. adamantinus sp. 
nov., D. mundus sp. nov., D. diJatans sp. nov., D. Ufidus, D. 
caduceus var. manuhriatus nov,, Oncograptus^ 0. wp- 
silon sp. nov., Goniograptus niacer, G. speciosus sp. nov., G. 
crinitus sp. nov., G. laxus sp. nov., Tetragraptus liarti sp. nov., 
T. whitelaivi sp. nov., Monograptus aplini sp. nov., M. turricu- 
latus, M. priodon, T riaenograptus neglectus gen. et sp. nov. 
He reriorted (77) on graptolites from 11 localities in the 
Steiglitz District and 40 localities in the Bendigo District. 
Chapman (79) gave the stratigraphic subdivisions of the 
Lower Ordovician of Victoria, based on T. S. Hall’s 
researches on graptolites (28). He also summarized the 
1 1903 Gregory, J. W., The Heathcotian— A Pre-Ordovician Series--and its 
Distribution in Victoria, Proc. Roy. Soc. Vict. (n.s.) xv, (II), PP- 
148-175. Melbourne.
