He also submitted a collection of predacious Diptera, along 

 with the prey upon which they were feeding when captured. 

 The former consisted chiefly of specimens of Scatophaya 

 stercoraria, L., and S. squalida, Mg., while the insects upon 

 which they were feeding were various species of Chironumidcc, 

 Bihionidcc, Tipulidw, &c. 



Mr. Malloch likewise showed specimens of Neottiophilum 

 prceustum, Mg., a dipteron new to the Clyde Area, which had 

 been bred from pupa; taken from the nest of a Greenfinch. 



On behalf of Mr. Charles Kirk, Mr. John Robertson showed 

 a colour-photograph lantern-slide of eggs of the Razorbill 

 and Common Guillemot. The variation in the colour and 

 markings were brought out very distinctly. It was stated that 

 this was probably the first occasion on which a slide of birds'- 

 eggs photographed by the new Lumi^re process had been shown 

 in Glasgow. 



Mr. Alexander Patience read a paper descriptive of 

 Trichoniscus linearis and Philoscia patiencei, two new British 

 species of terrestrial Isopoda. 



A paper entitled " Some observations on the Dipterous 

 Family Phoridce," communicated by Mr. J. R. Malloch (page 

 153), was read by Mr. Ross. 



Messrs. R. B. Johnstone and D. A. Boyd submitted a 

 Report on the Fungus Forays in 1907 (page 251). 



25th February, 1908. 



Mr. J. Ballantyne, Vice-President, in the chair. 



Messrs. J. G. Connell, 13 Ormonde Park, Muirend, Cathcart, 

 and John Muir, 128 Ledard Road, Langside, were elected 

 Ordinary Members. 



Mr. Peter Macnair, F.R.S.E., F.G.S., exhibited a specimen 

 of Petromyzon marinus, L., caught in the Clyde at Uddingston 

 in July, 1907, and a specimen of Gentrina salviani, Risso, 

 from the North Sea. He described the peculiar anatomical 

 features of these fishes, and stated that both species were very 

 interesting — the one for having, during spawning time, 

 come up the Clyde through the Broomielaw in safety, and the 

 other from being for the first time found as far north as the 

 British coast.
