Revieto^ — Contributions to Fossil Botany. 371 



The author considers tiiese beds the equivalents of the Upper beds of coal under 

 the Lower Carboniferous series of Scotland. The report by Mr. Baily OU' the fossils 

 confinns this opinion. The only fossils found belong to known species of the genera 

 Sigillaria and Lepidodendron.

 TMs volume contains lists, and sometimes descriptions and figures, of the plant- 

 remains found in the different formations within the boundaries to which it refers. 

 The new species are included in the systematic list.

 The author describes the minute structure of a Calamitean cone of the same type 

 as that to which Binney had given the name Bowmanites Cambrensis. Each whorl of 

 leaves in the cone supports several sporangia in a linear series.-

The author describes this fossil as having a true cellular pith and two kinds of 

 medullary rays. It could not be the root of Lepidodendron, and it showed that we 

 were still ignorant of the internal organization of Sigillaria.

The author describes- the minute structure of the stems, which he places in two 

 generic groups, the Calamites and Calamopitus, the former to comprehend those 

 without infranodal canals, the latter those which possess them.

 The author describes the structure of Lepidodendron, Sigillaria, Biploxylon, Ulo- 

 dendron, Halonia, and Favularia, and believes that all these forms are but modifica- 

 tions of the Lepidodendroid type.

 The authors give a systematically- arranged list of the known fossil plants, amount- 

 ing in all to ninety species, with the localities where they have been found.
