THE DESMIDIE/E OF EAST FIFE. 

 By JOHN ROY, LL.D. 



THE following short list has been made from material 

 gathered by Mrs. Farquharson, F.R.M.S., towards the close 

 of last year. 



The district is evidently not rich in Desmids, for though 

 my valued friend collected indefatigably all about St. 

 Andrews, from Blackballs to Newport, and inland as far as 

 Cupar (Tent's Moor proving by far the most productive), 

 yet the number seen is comparatively small. There are no 

 ne\v species to record, but some of those noted are scarce 

 elsewhere. Cosmarium microspkinctuni, Nord., forma parvnla, 

 Wille, is believed to be new to Britain, and the following are 

 very rare : Cosinariinii prunnorstnn, Breb. ; Cosviocladiuvi 

 constrictum, Archer ; XantJiidimii Brcbissonii, Ralfs., ft 

 basidentatinn, Borg. ; and Docidium Farquliarsonii, Roy. 

 The interest of the list lies in the fact that it relates to a 

 district of which, from a Desmidian point of view, nothing 

 was previously known.
