GRAPTOLITES OF AUSTRALIA 
graptus typus, Didymograpsus serratulus, D. caduceus, D. 
furcatus, Graptolites gracilis, G. logani, G. quadribrachiatus, 
G. octobrachiatus, G. ludensis, G. tenuis, G. latus and G. 
Sagittarius, forms common to both Europe and America. 
1862, — McCoy (8) published the foregoing list in the 
Annals and Magazine of Natural History in anticipation of 
the specimens being exhibited at the Intercolonial Exhibition 
to be held in London the following year. 
1863. — Salter (9) referred to “a remarkable coincidence 
even to minutae” in the graptolites from Victoria displayed 
by McCoy at the Intercolonial Exhibition with those of the 
Skiddaw Slates, remarking that “they agreed genus for 
genus, and almost specifically, with the North-of-England 
forms.” He inferred that “there is a peculiar zone or horizon 
of the Llandeilo rocks of which these genera of graptolites 
are characteristic.” In his list of graptolites from the 
Skiddaw Slates, he referred to a form as “Didy mo graptus sp. 
like G. pantoni McCoy.” He concluded by naming this form 
D. v-fractus and it is specifically distinct from D. pantoni 
(cf. 14). 
1867, McCoy (11) stated that “all the slates containing 
gold-bearing veins in Victoria were identical in age and 
character with those in North Wales in which the Romans 
worked the gold-mines of Cogofau.” The majority of the 
graptolites found in Victoria are found in the Welsh Llan- 
deilo Flags, the Cumberland and the Scotch Shales, and 
almost all those identified by J. Hall from Canada occur in 
Victoria. He added Diplograpsus palmeus (Barrande), D. 
bryonoides and V. nitidus to the list of Victorian foians and 
stated that “on the upper end of many specimens of D. 
palmeus there is a large, smooth, pear-shaped or heart-shaped 
appendage which he believed to be an ovarian vesicle.” 
1872. Nicholson (12) referred to Australia “in which 
some of the peculiar genera of the Skiddaw and Quebec 
groups have been discovered. Here we are compelled to 
assume that we have a case of migration, though we have at 
present no data whereby to decide whether the course of 
migration was from Canada to Australia (as is most 
probable), or vice versa.” 
1874. Etheridge (13) either figured or recorded eleven 
species from Victoria, nine of which McCoy had previously 
recorded and two that McCoy had exhibited at the Inter- 
colonial Exhibition as Didymograptus (?) fruticosus J Hall 
and B. pantoni ( ?) MSS. McCoy (14) described and figured 
ten species, viz.: Phyllograptus folium (His.) var. typus
