of the larvae. He showed, too, that greenish-coloured larvae, by 

 acquiring bad odour and secretions, and by congregating together, 

 made their presence known by the fetid atmosphere with which 

 they surrounded themselves as effectually as if they were gaudily 

 coloured.

SPECIMENS EXHIBITED. 



Mr. Peter Cameron exhibited a large and fine collection of galls, 

 chiefly Hymenopterous, remarking at some length on their varied 

 character, and giving descriptive notes regarding the insects which 

 emerge from them.

I. — Notes on a Carboniferous Sjiecies of Glauconome. 



By Mr. John Young, F.G.S., V.P. 



The group of Carboniferous polyzoons at present arranged under 

 the genus Glauconome seems to be more abundantly represented in 

 the limestone strata of Western Scotland than in other localities 

 where similar strata prevail. In the Society's Proceedings, vol. ii., 

 p. 325, and vol. iii., p. 353, Dr. Young and I figure and describe 

 what we believe to be eight new species, and I have now to bring 

 under your notice another species or variety, which I am inclined 

 to regard as new, and which I provisionally name Glauconome 

 recticarinata. This form is moderately common in the shale that 

 lies between the two beds of limestone so long worked in the 

 parishes of Blantyre and East Kilbride for various industrial 

 purposes, and from which so many interesting species of Polyzoa 

 and other Carboniferous fossils have been obtained. The species 

 of Glauconome under notice is found in bipinnate branching fronds, 

 in fragments varying from one to two inches in length — nearly all 

 the specimens being found with their celluliferous faces adhering 

 to the stone. I have been fortunate, however, in lifting from the 

 shale by the asphalte process a few well-preserved fronds, which 

 show the character of the celluliferous face in a state of excellent 

 preservation.
