EXCUKSION. 



Cambuslang and the South Bank of the Clyde. — Mr. Bichard 

 M'Kay gave an account of this excursion. The more characteristic 

 plants of the district were found in their usual haunts; the 

 Equisetum umbrosum was observed still growing at the locality 

 where it was found at the Society's excursion last year. It was 

 rather stunted, and did not fruit so readily, as only one fertile 

 plant was found. With regard to this station for it Mr. M'Kay, 

 in allusion to some newspaper correspondence, said it was found 

 by Mr. George Boss, a former member of the Society, and himself, 

 in 1872, but had been omitted to be reported at the time. 

 Anacharis alsinastrum grows abundantly in a pool in a disused 

 quarry. A search was made for the Pearl Mussel {Unio 7nar- 

 gariiifer), which was found still livmg in some numbers in the 

 bed of the Clyde opposite Carmyle and Kenmuir Bank. The 

 other Mollusca noticed in the Clyde were Lymncea peregra and 

 Ancylus Jluviatilis. 



Two species of humble-bees were observed — Bombus lucorum 

 and B. terrestris. Andrena albicans was also captured.
