GRAPTOLITES OF AUSTRALIA 
survive them, while Loganograptus logani only puts in an 
appearance when they, in their turn, have almost passed 
away. Graptolites are not always easy of recognition, but 
these forms all belong to readily-recognizable groups; the 
specific detenniuations, it is possible, may be incorrect, but 
the generic cannot be confounded.” 
He recorded and figured (45) from Belle Vale, Yass, New 
South Wales, a Monograptus which he ascribed to the M. 
duhius group. 
He described and figured (46) from Sandy’s Creek, 
Mitchell River, Didymograptus ovatus sp. nov. and Glosso- 
graptus hermani sp. nov. 
He tabulated the species already recorded from Upper 
Ordovician localities. 
He recorded from Castlemaine, Goniograptus macer, Didy- 
mograptus aif. nitidus and D. extensus. From a locality IJ 
miles south-west of Kelly’s Hill, Matlock, he recorded Dicel- 
lograptus morrisi, Diplograptus foliaceus and other forms 
and assigns the beds to the Upper Ordovician. 
He examined (47) the graptolites in the collection of the 
Geological Survey of New South Wales. From Stockyard 
Creek, he identified DiceJlograptus affinis, D. cf. divaricatus, 
Diplograptus carnei, D. foliaceus, Climacograptus Mcornis, 
C. Jiastata, C. tuhuliferus, Cryptograptus tricornis (vide 63), 
and Ttetiolites caudatus; from Currawang, ( ?) Dicello- 
graptus affinis, Dicranograptus zic-zac var. minhnus, Diplo- 
graptus foliaceus, Climacograptus hicornis and C. tuhidiferus 
( ?) ; from Lawson, Dioxmograptus zic-zac var. minimus, 
Glossograptus cf. mucronatus and Clathrograptus cf. geini- 
tzianus; from Orange, Diplograptus carnei; from Tomingley, 
Dicellograptus cf. divaricatus, Diplograptus carnei, D. folia- 
ceus, D. cf. whitfieldi, Climacograptus tuhuliferus, Callo- 
graptus cf. salteri, Dictyonema sp. and Dendrograptus spp. 
He described and figured Dicellograptus affinis sp. nov., 
Diplograptus carnei sp. nov., Climacograptus hastata sp. nov. 
and Retiolites caudatus sp. nov. “Certain species identified 
from Victorian rocks by the late Sir F. McCoy,” he said, 
“namely, Diplograptus mucronatus J. Hall, D. rectangidaris 
McCoy and D. palmeus Barr, are not those species, the two 
latter, indeed, not occurring in Ordovician rocks at all, but 
being characteristic of Silurian age.” 
He discussed (48) the evidence for the existence of grapto- 
lites at a locality near the Ring River, north-east of Dundas 
Railway, and from near Zeehan, both in Tasmania.
