GRAPTOLITES OF VICTORIA. 
Thecae 11 to 13 in 10 mm., slightly curved, inclined at 40° to 50° ; in contact 
throughout ; apertural margins forming a more or less broken line representing 
margin of compressed polypary. Test somewhat attenuate. 
Remarks . — The median suture is indistinct but is apparently 
wider than that of T. wilkinsoni T. S. Hall or T . ensiformis 
J. Hall (see T. S. Hall, 8, and J. Hall, 6, pi. 14). Its spindle- 
shaped polypary and the absence of subparallel margins may be 
merely characteristic of a stage of development. Until better 
specimens are available, we have contented ourselves by referring 
it to its genus. 
Associated graptolites. — The typical assemblage of Zone Dl, Darriwil Series ; 
see Didymograptus acriculus, p. 167. 
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 local outcrops of the same strata. 
Genus GLOSSOGRAPTUS Emmons 1855. 
Glossograplus pilosus, sp. nov. 
(Plate XXI, figs. 5a-5d.) 
Polypary oval, fusiform or subcircular ; 3.6 mm. long, about 2.0 mm. 
broad. Sicula about 1 .0 mm. long. Thecae from 22 to 27 in 10 mm. ; overlap 
three-fourths of length ; ventral margin straight ; apertures everted ; from 
sicula to distal extremity facing downwards, outwards, and upwards ; furnished 
with robust, arcuate, blunted spines. Virgula stout, about 1.5 mm. long. 
Remarks. — G. pilosus differs from G. hystrix Rued, (see 
Ruedemann, 12) in general shape, relative shortness, more 
closely set thecae, and its arcuate spines. The distal thecae 
may grow to abnormal size and produce unusually long spines. 
The sicula has sometimes an extremely fine virgella. The 
septal spines are robust though seldom visible. The apertural 
spines often widen into a dilation, suggesting affinities to the 
genus Lasiograptus. 
Associated graptolites. — Those found 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 occasionally in other local outcrops 
of the same strata, as in Sect, xxix, Parish of Huntley. 
Genus CRYPTOGRAPTUS Lapworth 1880. 
Cryptograptus circinus, sp. nov. 
(Plate XXI, figs. 6a-6e, and text fig. 5.) 
Polypary widening rapidly to approximately 3.0 mm., attaining 18 mm. in 
length. Sicula obscure ; minute virgella. Thecae 13 to 15 in 10 mm. ;
