GRAPTOLITES OF AUSTRALIA 
67 
yielded corals and a starfish bed. With this a graptolite cf. M. nilssoni 
was found. 
(c) The upper beds yielded abundant graptolites, M. colonus var. compactus, 
M. uncinatus var., M. bohemicus and M. varians and fossils other than 
graptolites. 
W. J. Harris and D. E. Thomas (154) published descrip- 
tions and figures of the following species : 
(a) From the Heathcote district — 
Monograptus hohemicus, M. colonus var. compactus, 
M. varians, M. uncinatus var, orhatus, M. uncinatus 
var. micropoma, M. sp. aft. nilssoni and M. cf. comis. 
(b) From the Kilmore district — 
Diplograptus sinuatus, Climacograptus hugliesi, 
Monograptus runcinatus, M. ( *?) nudus, M. priodon, 
M. exiguus (syn. M. aplini T. S. Hall), M. spiralis var. 
permensis, M. duhius. 
(c) From the Yarra Track — 
M. uncinatus var. orhatus, M. uncinatus var. micro- 
poma, M. vomerinus and M. vomerinus var. crenulatus. 
(d) From the Melbourne district — 
M. crinitus, M. diibius. 
1938. — W. J. Harris and D. E, Thomas (155) dealt with 
the basal Bendigo (B5) assemblage from Allot. 16 A, Parish 
of Campbelltown, They stress some of the features shown by 
the assemblage: 
“ (i) Instability of branching, so that Dichograptid or 
Loganograptid forms with from six to sixteen branches 
occur, together with five or six branched forms otherwise 
indistinguishable from Tetragraptus fruticosus {vide Bryo- 
graptus crassus infra). Three branched forms which are 
apparently three-branched representatives of horizontal 
Tetragrapti are also found.” 
“(ii) A great variety of extensiform Didymograpti 
including a series with ‘closed’ apertural regions {D. hirundo 
type) without any evidence of ancestral history as they are 
quite distinct from the rare Didymograpti recorded from the 
next lower zone (LI). 
“ (iii) Abnormal Clonograpti of great size with distinctive 
thecae of the Tetragraptus cJiapmani type.” 
“The higher beds (B4) are also extremely interesting as 
from them we are able to record for the first time from 
Australia the genera Trochograptus and Schisograptus, both 
with abnormal features, while the three-branched forms 
referred to above are not uncommon. This list by no means
