NATDKAL HISTORY SOCIETY OF GLASGOW. XXV 



Mr. James J. F. X. King exhibited specimens of Lyi^^ fragiUs, 

 Pict., and Ayapetus dellcatulus, M'Lach., two species of Tri- 

 choptera captured by him in Ireland but not yet discovered in 

 Britain. 



The Chairman (Mr. Somerville) exhibited specimens of ArgiojiC 

 capsula, Jeffreys, a Brachiopod dredged by hina off lona, in 

 December, 1887, but not previously recorded for tlie Scottish 

 •Coasts. 



He also showed specimens of Malaxis paludosci, Sw., from 

 Ben Laoigh. 



Mr. D. A. Boyd exhibited specimens of Craterium minutum, 

 Leers, Ciiciirbitar'ia herberidis. Gray, C. lahurni, De Not., 

 Leptosphfpria nisei, (De Not.) Sacc, and other Fungi from 

 West Kilbride. 



Dr. John Grieve, F.R.S.E., F.L.S., showed a young specimen 

 of the John Doi'y [Zeus faher), also examples of Dysldea 

 fragilis, Cliallna oculata, Hallcliondrla panicea, and Isodictya 

 simulatis, four species of Sponge from the Sussex Coast. 



Mr. George Russell exhibited a specimen of an unusual form 

 of Coilogyne cristata, one of the Orchidaceaj, having variegated 

 leaves. He stated that the normal colour of the leaves is dark- 

 green, and the pseudo-bulbs are of a lighter shade. Although 

 he had grown this species for about twenty years, he had never 

 before seen it show any tendency to diverge from its normal 

 colour. It is therefore very difficult to account for the departure 

 in the instance under notice. The specimen from which it 

 sprang was very vigorous, and this fact may to some extent 

 explain the change of colour. Mr. Russell was inclined to think 

 that the flow of sap in the growing plant had probably been 

 more than the young leaves could assimilate, and some of the 

 channels may have become partly closed, thus leading to a 

 larger amount of chlorophyll being formed in some parts of 

 the leaves than others. 



He also showed a specimen of Sfoiia pallida, one of the 

 Orchidaceae, chiefly interesting on account of the shape of the 

 flowers, which exactly resemble in form the oil-lamps xisecl in 

 Greece during classic times, and in our own country a few 

 generations ago. 



Mr. Thomas King, Vice-President, showed some very beautiful 

 specimens of Lachnea {Sai-coscyjiha) coccinea, Jacq., gathered 

 by him at Finlaystone, near Langbank. 



Mr. David Robertson, F.L.S., F.G.S., communicated a paper 

 entitled "Notice of thirteen Cumacea from the Firth of 

 Clyde."* An ample scries of specimens of the various species 

 referred to was submitted for exhibition.
