 the dark coloured muriculate spores. 



The rediscovery of this rare liverwort in Ireland would be of great 

 interest, it having been found many years ago on a wet clay bank at 

 Collin glen near Belfast by Mr. David Orr, an excellent bryologist. 

 Dr. D. Moore in his work on Irish Hepaticse writes '* I have never seen 

 any Irish specimens ot this plant, nor have I heard of it having been 

 observed by any other person than Mr. Orr in Ireland." 



In the " List of the Irish Hepaticae," {Proc. R. I. Acad., Vol. xxiv., 

 Section B., p. 496), the exhibitor appended the following note regarding 

 this plant : — 



•'Stubble fields and similar places have been neglected by collectors, 

 and there is no reason why the plant should not be rediscovered." The 

 specimens exhibited were kindly sent by Canon Lett. 



G. H. Carpenter showed a new species of Nymphon, collected by 

 Prof. Herdman on the pearl banks of the Gulf of Manaar, and remark- 

 able from the comparatively great length of the abdomen and the 

 regular arrangement of pigment on the trunk. A cheliforus and the 

 terminal segments of an ovigerous leg with denterulate spines were de - 

 monstrated under the microscope.

 H. Carpenter, B.Sc, in the chair. An account of the Sligo district to 

 be visited by the Club on the occasion of the Field Club Union Conference
