growth in the deeper and more inaccessible water. I very 

 much doubt whether the locaHty yields many other species. 

 At any rate there must be numerous localities of Ireland 

 still unexplored which would repay search far more 

 generously. These notes may serve as a warning to 

 botanists who may be attracted by the promising appearance 

 of the neighbourhood as portrayed in the Ordnance Survey 

 map. 



The poor results of my visit to the Rosses impelled me 

 to turn aside on my return journey to Derry and pay 

 another visit to Fanad where several records of the 

 previous year needed some confirmation, I spent a week 

 at Kindrum and was able to collect some fruiting specimens 

 of the little Nitella growing in Kindrum Lough referred 

 to in my previous paper as probably A^. batrachosperma, 

 Braun {N. Nordstedtiana, H. and J. Groves). A careful 

 examination of the membrane of the oospore confirms the 

 accuracy of Mr. James Groves' opinion. The plant proves 

 to be undoubtedly N. batrachosperma, and the discovery 

 must be regarded as a very interesting link between its 

 two previously recorded stations — the one in the Orkneys, 

 and the other in County Kerry. 



The curious variety of A^. flexilis (if such it be) growing 

 along the margin of L. Shannagh suggested that other 

 treasures might be found on the lake with the aid of a boat. 

 I was able with some difficulty to obtain the use of a curragh 

 and the services of a boatman skilled in the management 

 of this rather frail form of craft. But the lake yielded 

 nothing further so far as I could discover, not even specimens 

 of the Nitella flexilis beyond the thick bank of growth 

 reachable from the shore which I had found last 3'ear. Here 

 I found it still growing and fruiting in great abundance and 

 maintaining its distinctive and abnormal characteristics. 

 This plant and the variety of C. contraria from L. 

 MuUaghderg seems to call for some special notice, and I 

 hope that Mr. James Groves and I shall be in a position 

 to make a communication on the subject in the course of 

 a few months.
