Phyllotheca concinna, n.s., plate IX., fig. 2. Stems neatly 

 striated with 15 to 18 ribs terminating in linear leaves 

 which, though slightly curved, do not spread, but lie almost 

 parallel to the stem. 



Common in the shales of the Hawkesbury sandstone at Sugar- 

 loaf Hill, and along the canals and tunnels of the waterworks. 



I distinguish this species (1) by the broad stems, (2) the close- 

 ness and neatness of the ribs, (3) the leaves scarcely spreading, (4) 

 leaves not half the length of Phyllotheca Australis. 



Phyllotheca carnosa, n.s., plate 9, fig 2. I name thus a 

 species of which I have seen only one faint impression from the 

 Walloon Mine. It is imperfect, but shows a close succession of 

 verticillate leaves, which radiate very slightly from the stem. 

 They are close obtuse, about half a millimetre wide and 5 long. They 

 form 5 cup-shaped divisions on a stem 35 mill, long and 10 wide. 

 It seems allied to P. robusta of the Indian Lias (See Feist. 

 Gond. Syst., Vol. III., p. 68, pi. xiv. a, bis, fig. 1 and 2.) This is 

 also closely allied to P. schtschurowski, of the Siberian Jura. The 

 shale specimen from which the figure was taken has fallen to pieces. 



Vertebraria. 



This peculiar plant was erected into a genus by Prof. Royle in 

 his Botany and Nat. Hist, of the Himalaya Mounts.* It was for 

 two fossil plants from Burdwan, but no description or definition is 

 given. Prof. Morris in his examination of the Australian coal 

 plants, in Strzelecki's work already referred to, mentions (p. 253) 

 the occurrence of the same fossils (Vertebraria indica and V. 

 racliata among the Newcastle coal plants. Prof. M'Coy was the 

 first to give any definition of the genus. Prof. Dana subsequently 

 described two of the same fossils from Australia under the name 

 of Clasteria.
