Callistemophyllum Hackii, sp. nov. 
Plate XV, Figs. 20, 20a. 
Sp. Char. — C. foliis subcoriaceis, lanceolato-linearibus, basin versus 
sensim attenuatis, margine integerrimis ; nervatione brochidodroma ; nervo 
primario distincto recto ; nervis secundariis tenuissimis subangulis 15-25° 
orientibus, inter se remotis, flexuosis, nervo marginali inter se conjunctis ; 
nervis tertiariis tenuissimis vix conspicuis. 
Ohs. — A narrow, nearly linear leaf, gradually contracted towards the 
base. Its texture seems to be scarcely coriaceous. Its lamina shows 
numerous dots, which correspond to oil glandules. The primary nerve is 
comparatively thin. The secondary nerves being very fine, and somewhat 
undulate, 5 to C> millimeters distant from one another, diverge at very acute 
angles. The marginal nerves, joining the secondary ones, are prominent. 
The tertiary nerves are scarcely discernible, and rather hidden by strongly 
prominent folds which have been accidentally produced in the stone after 
fossilization of the enclosed leaf. The glandules are, nevertheless, distinctly 
visible. (See Fig. 20a, enlarged.) Analogous leaves are to be found in the 
genera Callistemon, Melaleuca, and Eucalyptus ; for instance — Melaleuca 
linear iifolia , Smith, Eucalyptus amygdalina, Labill., &c. Of the hitherto 
described fossil species of the Callistemophyllum hilinicum, Ett., approaches 
nearest to our species. 
Locality and Horizon. — Fox and Partridge’s claim, between Pose 
Valley and the lied Hill, 2 miles from Emmaville (Vegetable Creek Town- 
ship) ; ironstone shale in Newer Leads (stanniferous), below basalt. 
Callistemophyllum Beckeri, sp. nov. 
Plate XV, Figs. 17, 18. 
Sp. Char. — C. foliis coriaceis, lineari-lanceolatis, integerrimis ; nerva- 
tione brochidodroma ; nervo primario prominente ; nervis secundariis sub- 
angulis 25-35° orientibus, approximates, tenuibus, flexuosis, ramosis, nervo 
marginali prominente inter se conjunctis; nervis tertiariis parce evolutis sub 
angulis variis exeuntibus. 
Ohs. — Two leaves of this species lie before me, represented here in 
PI. XV, figs. 17 and 18. They are smaller than those of the other species 
of the above genus here described, but comparatively broader than that of 
the preceding one. The secondary nerves being fine, llexuous, and approxi-
