128 The Irish Naturalist. Aug.-Sept, 



Bowell's original paperi either in size, shape, or tenuity. 

 They also bear little resemblance to the Nagarriva 

 specimens from which the description was made, but have, 

 on the other hand, a strong family likeness to '' L. pereger" 

 collected by me in many localities in the west and south- 

 west of Ireland. 



I am sensible of the gravity of my omission in giving 

 no anatomical details in this paper and can only say as 

 an excuse that I am no anatomist myself and all those 1 

 know are at present otherwise engaged owing to the war. 

 It was my first intention merely to write a short note 

 recording my new captures in the Caha Lakes, and to 

 continue my investigation of other lakes in those mountains 

 in the future, waiting till after the war when I could have 

 dissections made of specimens from each locality before 

 publishing these notes, but private reasons render it unlikely 

 that I shall be able to visit Ireland again in the near future 

 and present publication imperative. 1 have a few specimens 

 preserved in spirit for the future, and must be content 

 with this, but wish to emphasise the fact that my conclusions 

 are not based on a random collection of shells but on a 

 careful investigation of local conditions which may at any 

 rate have some value to future workers.

OBITUARY. 



ROBERT OLIVER CUNNiNQHAM. 



The announcement of the death of Dr. Robert O. Cunningham, at 

 the age of 77 years, will be received with much regret by many Ulster 

 naturalists who were associated with him during his thirty years' occupancy 

 of the chair of Natural History at Queen's College, Belfast. He was 

 born in 1841 at Prestonpans, Scotland, where his father was minister 

 of the Free Church, and graduated in 'cience and medicine at Edinburgh 

 University. As a young man he was attached as naturalist to a 

 scientific expedition to South America, and published on his return an 

 account of the voyage in whicli he added to the knowledge of the natural 

 history of Patagonia and Argentina. Shortly afterwards (in 1871) he 

 was appointed to a comprehensive chair, whose occupant " professed " 

 the three natural sciences of zoology, botany, and geology at the Queen's
