From the Wood’s Point District, Nos. 236-256. 
(By T. S. Hall, M.A.) 
Nos. 236-255 are from the Yarra Track, 1| miles south-west of Kelly’s Hill. 
No. 256 is from the Wood’s Point Company’s tunnel, Wood’s Point township. 
The list of species, as far as the somewhat imperfect nature of the material 
allows of identification, is as follows :— 
Dicellograptus affinis, T. S. Hall. Specimens 236, 237, 239, 241, 242, 
243, 245, 246, 247, 249, 250, 252, 253, 254, and 255. 
Dicellograptus sp. Specimens 240, 247, and 251. 
Diplograptus foliaceus, Murch. Specimens 236, 240, 248, and 253. 
Diplograptus cf. foliaceus, Murch. Specimen 243. 
Diplograptus cf. tamariscus, Nich. Specimens 236, 238, and 252. 
Diplograptus sp. Specimens 239, 242, 247, 249, and 256. 
Climacograptus hastatus, T. S. Hall. Specimens 237 and 254. 
Climacograptus tubuliferus, Lap. Specimen 254. 
Climacograptus cf. innotatus, Nich. Specimen 244. 
Climacograptus sp. Specimens 245, 247, and 255. 
Dendrograptus (?) sp. Specimen 246. 
Hitherto I have been unable to do much more than attach tentative names 
to graptolites from the Wood’s Point (Matlock) districts, but having recently 
had a better preserved collection from New South Wales in my hands, I am 
able to assert some specific identities which have been made by actual com¬ 
parison of specimens. The list given above shows some striking resemblances 
to that from Stockyard Creek, county of Wellesley, New South Wales, a 
locality close to the northern border of Croajingolong, the four species definitely 
determined occurring also at the New South Wales locality. On the other hand, 
Climacograptus bicornis, so characteristic of the Stockyard Creek series, is not 
present apparently at Matlock. One of these species is a European one, and 
the other three are closely allied to European forms. Climacograptus tubu¬ 
liferus, and the three allied to our Australian ones, are associated in Britain. 
The range of the two species which are only compared with European ones, 
namely, Diplograptus cf. tamariscus and Climacograptus cf. innotatus, is, 
however, quite different, for in Britain they are silurian (upper silurian) only, 
whereas the Wood’s Point beds are undoubtedly upper ordovician. The 
specimens of the two species are only indifferently preserved, though repre¬ 
sented by several examples. Thus in Diplograptus cf. tamariscus the form of 
the polypary, with its pointed base, its prolonged virguJa and virgella, and the 
shape of the thecae, seem identical with the European form, but ours is slightly 
larger. The same may be said of Climacograptus cf. innotatus, the form of the 
thecae, with their curiously placed spine, and the habit of the polypary, remind 
us of the British species, but again ours is a little larger. Even if the species 
are distinct, still their facies is younger, judged by European standards,than 
that of the named species in the beds. 
The collection is of interest as showing the similarity in age between the 
upper ordovician Matlock beds and the New SouthWales series, which, with 
an almost identical fauna, has been traced at intervals from Deddick, in Vic¬ 
toria, to Tomingley, in New South Wales, a distance of more than 300 miles 
from north to south.
