tion of the leaflets are well defined. Under the microscope the 

 Dervures have a striated appearance, and there is a more delicate 

 longitudinal striation visible in the epidermis of the leaf. I may 

 remark here, that though in a somewhat altered rock, and to a 

 cursory glance indistinct, the leaves and other delicate vegetable 

 organs in the shales of St. John, are found under the microscope 

 to present an unusual degree of perfection in their finer markings. 

 They must in the first instance have been imbedded in a quite 

 unchanged condition, and but for the alteration which the rocks 

 have sustained, would have furnished remarkably perfect speci- 

 mens. The species above described approaches most nearly to 

 S. erosum of the coal measures, but differs in its proportions.

Description. — Leaflets one veined, narrowly ovate-acuminate, one-tenth 

 to one-fourth of an inch in length, somewhat loosely placed on a 

 very slender stem, apparently in a pentastichous manner. 



This pretty little species is abundantly displayed in graphite, in 

 the Cordaites shale I have already referred to. With it are found 

 the little scales or Lepidophylla, (Fig. 8, d.) which may possibly 

 have belonged to its fructification. 



In addition to the above plants, there is in the sandstone con- 

 taining conifers, an impression of the bark of a plant which may 

 have been a Sigillaria. In the Cordaites shale there are many 

 indeterminable fragments, among which are a small fern leaf, ap- 

 parently a Splienopteris like >S^. Devonica, linger, a terminal pin- 

 nule of a Cydoj)tens, which appears to be the same with that 

 described below fiom Perry, leaves having the appearance of 

 those of Sigillaria, (Cyperites), and stems which may belong to 

 .Psilojphjton, There are also some remarkable fragments which
