A NEW NITELLA.

In August, 1916, I visited Kindrum in the Fanad Peninsula, 

 County Donegal, with a view to searching for Charophyta 

 in the series of lakes which border on the sea at its 

 northern extremity. One of these lakes, Lough Shan- 

 nagh, lies at the extreme north-east of the peninsula. It is 

 something under half a mile long and a quarter of a mile 

 broad, and does not exceed 10 or 15 feet in depth. Its 

 northern end, where its shore touches the sandy stretch 

 which divides it from the sea, has a sandy bed ; otherwise 

 it has a stony bottom and seems to possess little submerged 

 vegetation. On its western shore the drag brought up two 

 NiteUas, growing closely intermixed in about 4-6 feet of 

 water — the one, N. translucens, in sparse quantities, the 

 other growing in great profusion, dull olive-green in colour, 

 very delicate and fragile in habit, and bearing abundant 

 fruit. Its interesting character was not at once observable, 

 but under the microscope it proved to be a plant with very 

 distinctive characteristics. Its exceedingly fragile nature 

 made it very difficult to collect and handle, and almost 

 impossible to lay out on paper with any good results. 



I paid another visit to Kindrum in August, 1917, for 

 the purpose of making a further examination of this Nitella 

 and its habitat and, if possible, of collecting better speci-
