A nne-lookiug well-preserved fossil leaf. There is no doubt 

 as to its designation as belonging to the Apocynaccce. A frag- 

 ment of the petiole about ISinni. long has been preserved, but 

 iis the rock is broken it is impossible to give the exact length 

 ■of the stem ; the texture was leathery. The nervation shows 

 ii prominent straight priinary nerve, which diminishes con- 

 siderably towards the point. Tiie secondary nerves are fine 

 and numerous, they are close together, winding, and start 

 iiearly at right angles from the primary nerve ; the secondary 

 nerves are connected with each other near the edge by 

 anastomosing loops. The tertiary nerves are short, and 

 start i)-regularly at different angles ; they are also branched 

 iind resolve in a net, consisting of rather loose irregularly- 

 ■cornered meshes. Apocynopliylhnn Iwlvcticum, Heer, from 

 the Tertiary flora of Switzerland; A. alstonioidcs, Ileov, a.nd 

 £umatrcnsc, Heer, of the Tertial-y flora of Sumatra ; and 

 Also A. mackinlayi, m., of the Australian Tertiary flora, may 

 be considered as analogous species, which are only dis- 

 tinguished from the species described by the better-developed 

 formation of the reticulation.

Notwithstanding that the fossil leaf shown on fig. 13 is im- 

 perfectly preserved, it is possible to complete it with tolerable 

 certainty as a petiolate lanceolate leaf, which becomes narrower 

 towards the base, the texture of which seems to have been 

 delicate. The primary nerve is fine and straight ; the second- 

 ary nerves are also fine, parallel with each other, and some- 

 what curved. They start at somewdiat acute angles. Only 

 ^in two places in the fossil is it possible to discover that the 

 tertiary nerves start at right angles. The fossil shows the 

 best agreement with Apocynopliylliini taberncemontana, Ung. 

 (Syll. Plant. Foss. iii., pi', iv., "fig. 9, of the fossil flora of 

 Radoboj), which I conclude to be tlie most nearly related to
