GRAPTOLITES OF VICTORIA. 
indicates that the thecae are approximately 2.0 mm. long and 
overlap about one-half their length. 
Associated graptolites. — Retiograptus pulcherrimus, sp. nov., Climacograptus 
missihs Keble & Harris, C. tubuliferus Lapworth, D. carnei T. S. Hall, Lepto- 
graptus eastonensis Keble & Harris, L. flaccidus J. Hall. 
Horizon. — Upper Ordovician, Bolinda Series. 
Locality. — About 10 chains west of Jordan River where it crosses the 
Yarra Track, between Matlock and The Oaks. 
Climacograptus subminimus, sp. nov. 
(Plate XX, figs. 6a, 6b.) 
Polypary 15 mm. long, widening rapidly to maximum width of about 1 mm. 
Virgella conspicuous. Virgula relatively stout ; 6 mm. or more in length. 
Thecae 10 or 1 1 in 10 mm. ; long, overlapping from one-half to two-thirds of 
length ; free outer edges straight and vertical ; apertural margins horizontal, 
lying within sub-elliptical excavations occupying one-third width of polypary 
and one-third of ventral margin. Septum incomplete. 
Remarks. — In some specimens there is a suggestion of a 
rudimentary basal spine. C. subminimus seems intermediate 
between C. minimus Carruthers and C. brevis Elies and Wood ; 
from C. minimus it is distinguished by its lesser width, and 
from C. brevis by its greater thecal overlap. This graptolite 
is referred to Climacograptus with some hesitation, but its 
inclusion in the genus is supported by comparing it with figures 
of related species ; see Elies and Wood, 2, p. 193, fig. 1256. 
Associated graptolites. — The same as with Didymograptus acriculus. 
Horizon. — Lower Ordovician, Darriwil Series, Zone Dl. 
Locality. — Bendigo East, on south side of Bendigo-Axedale Road, about 
30 chains east of Whitelaw Fault, and at other outcrops of the same belt of 
strata in this locality.

In some of the Upper Darriwil beds a Diplograptus occurs 
which is intermediate between D. ( G .) euglyphus and D. ( G .) 
teretiusculus (Hisinger), see Elies and Wood (3). The maximum
