In conclusion I must acknowledge my indebtedness 

 to several people in the course of this work. To W, H. 

 Sutcliffe, Esq., as before stated, for the generous way in 

 which he placed the specimen in my hands ; to the 

 Authorities of the Berlin Museum and Count Solms 

 Laubach for the loan of their valuable type specimens of 

 the allied species T. Solenites ; to Prof Weiss, in whose 

 department the work was done, for his kindly and helpful 

 interest ; to Prof Oliver, for permission to examine the 

 specimens of Botryopterideae at University College, and 

 other kindness ; and to Mr. D. M. Watson for photo- 

 graphing a number of the sections. I may add that 

 owing to Mr. Sutclifife's generosity, the whole of the 

 specimens have been deposited in the Manchester 

 Museum, with the following exceptions : — Sections T 13, 

 T 4, L 14, have been presented to Prof F. W. Oliver,
