40 The Scott is J i Naturalist. 



I find that Delponte, in his excellent work, " Specimen Desmidiaceraum 

 Alpinum" supposes Kutzing's species to be the same as Ralfs' Dotid. Baculum, 

 which may be ; but in the absence of drawings or specimens from Kiitzing 

 himself, I am quite convinced that it is impossible to identify his species, and 

 as his name suits the one under consideration very well, I have taken the 

 liberty of adopting it. 



The following 26 species were found in a gathering made by Dr. Buchanan 

 White in Skye, I think on Ben Blaven.

NOTE ON THE OCCURRENCE OF CERTAIN FERNS ON THE 

 RAILWAY BETWEEN CARGILL AND WOODSLDE. 



Having heard that Scolopendrium and various other ferns were to be found at 

 Woodside, on the railway between Coupar- Angus and Perth, I visited the place 

 in the end of October last with a view to ascertain the facts of the case. As 

 the season was so far advanced, I did not expect to verify what I had heard by 

 personal observation ; I, therefore, called upon Mr. Ilopkirk, the intelligent 

 station-master at Woodside, who furnished me with the following particulars, 

 and also showed me the ferns growing in his garden, which he had himself 

 gathered on the ground in question. 



Scolopendrium, he told me, had been found on the line for the last fifteen
