Obs. — Very tender forked branclilets which very much resemble those 
of Callitris Brongniartii , var. gracilis, from the Tertiary Flora of Haering. 
lhit the remains from Vegetable Creek are still more slender and thinner 
than the latter. Of the mere fragments from the above locality, the best are 
now figured (Figs 3 and 4, natural size, fig. 3a magnified). 
Of the living species, the Australian Callitris rolnista, 14. Brown 
{Brencla, Cunningli.), may be the nearest ally of the fossil. 
Locality and Horizon. — Old P-ose Valley Lead, with the preceding 
species. 
Genus — HETEROCLADISCOS. 
Gen. Char. — Cupressinese ramulis foliisque dimorphis, foliis inramulis 
adultioribus spiraliter dispositis dense confertis ; in ramulis junioribus decus- 
satim oppositis quadrifariam imbricatis. 
IIeteiiocladiscos tiitjjoides, sp. nor. 
Plate VIII, Pigs. 5-7. 
Sp. Char. — II. ramulis strictis squarrosis, foliis ramulorum adultiorum 
ovato-lanceolatis acuminatis subpatentibus ; juniorum minoribus ovato-rhom- 
beis, obtusis, dorso convexo carinatis, arete adpressis, ramulos tetragonos 
f orman tibus. 
Obs. — A very remarkable cupressus-like conifer, which shows the type 
of G'lyptostrobus in its primary branclilets, but that of Thuites Mengeanus, 
Goepp., from the Amber, in its secondary ones. The former are cylindrical, 
and bear lanceolate and acuminate leaves, which are arranged close to one 
another in spiral order, only with the base oppressed (See PI. VIII, fig. 5a, 
magnified). The latter are four-edged, bearing rliomboidal or broad ovate 
leaves, which are arranged in four rows, imbricate, and quite oppressed. 
Their apex is somewhat obtuse, and their exterior plain vaulted, with an obtuse 
midrib. (See PI. VIII, fig. 6a, magnified.) The branclilets, especially the 
secondary, are straight, stiff, and squarrose. The peculiar similarity of the 
secondary branclilets to those of Thuites Mengeanus may be due to the 
arrangement of the leaves, but those of the latter species are acuminate. 
Locality and Horizon, — Old Rose Valley Lead, with the preceding 
species.
