the abrasion and decay of their long journey from the uplands 

 to the flats, where mud or sand was being deposited ; and as 

 proof of this, many of the stems of these trees are found 

 imbedded in sandstone quarries, where they have been 

 drifted. 



The undoubted occurrence of the genus Schutzia, so low 

 down in the geological scale, is of considerable importance ; 

 the discovery in the Calciferous Sandstones of a plant so 

 closely related to a Permian species, is almost without parallel. 



The small fossils which I previously described and placed 

 in the genus Schutzia are different from the present example, 

 and their real claim to this genus may perhaps be open to 

 question.^ 



Schutzia Bennieana comes so near the Permian species, 

 that it is only after very careful consideration I have given 

 it a specific designation.^ 



It gives me pleasure to name this plant after Mr J. Bennie, 

 to whom I owe so much for kind assistance in many points 

 connected with my study of fossil botany.

Although both the late Dr Saxby and Mr Thomas Edwards, 

 of Banff, write of having seen Sabine's Gull, there are only 

 two instances that I can trace of the bird having ever been 

 obtained in Scotland. The first, an immature female, shot 

 on October 2, 1877, near the island of Craigleith, in the
