GRAPTOLITES OF AUSTRALIA 
G. F. K. Naylor (141) indicated on a map of the Goulburn 
District, New South Wales, Upper Ordovician localities 
yielding CUmacograptiis, Diplograptus, Dicranograptus and 
DiceUograptus. From a locality on the Bungonia-Goiilhurn 
Road, about three miles west of Bungonia, he recorded Lower 
Silurian forms comparable with Monograjdus harrcmdei and 
M. exigims. He also recorded from a locality on the main 
Sydney Road near the Towrang turn-off Monograptus of an 
Upper Silurian type. D. F. Thomas {ibid. p. 80) suggested 
that it was M. hohemicus and probably contemporaneous with 
the zone of M. nilssoni. Naylor himself tentatively deter- 
mined another form as M. nilsHoni. 
W. N. Benson and R. A, Keble (142) wrote on the geology 
of the regions adjacent to Preservation and Chalky Inlets, 
Fiordland, New Zealand, and correlated the New Zealand 
assemblages with those of Victoria. They described and 
figured a number of species, some of which were new and 
should occur in Victoria. In particular, they referred Lepto- 
graptus antiquus T. S. Hall to the genus Bryograptus. 
1936. — G. F. K. Naylor (143) recorded from a locality 
between the third and fourth mile-posts on the Bungonia- 
Goulburn Road (presumably the locality mentioned in 141) 
Monograptus exigims and M. harrandei and in addition M. 
undiilatus, M, cf. decipiens, M. cf. tortilis. He recorded from 
the Upper Ordovician Diplograptus quadrimucronatus and 
D. calcaratus var. tenuicornis. 
He described and figured from more or less specified locali- 
ties Monograptus hohemicus, M. exiguus, M. cf. decipiens, 
M. undulatus, M. cf. tortilis, Diplograptus (Orthograptus) 
quadrimucronatus and D. (0.) calcaratus var. tenuicornis. 
He described M. harrandei. 
R. A. Keble (144) recorded and figured from the Bendigo 
Series a form in which the flat spiral polypary and thecae 
growing upwards in a single linear series seemed to him to 
leave no other alternative than to place it among the 
Monograptidae. 
O. ]\I. B. Bulman (145) made serial sections and dis- 
sections of the graptolites of the Holm Collection from which 
he made wax models and traced their history and evolution 
by a close study of the initial part of the rhahdosome. This 
important woi-k threw considerable light on such peculiarly 
Australian genera as B rachiog raptus Harris & K., Cardio- 
graptus Harris & K., Goniograptus McCoy, Oncograptus 
T. S. Hall and many cosmopolitan genera. 
He also investigated (146) by serial sectioning and grind-
