into South Africa, at Capetown, by a Frenchman, for gastro- 

 nomic reasons. In this case the shell showed a tendency to 

 become thicker. 



Mr. Robert M'Lellan exhibited a proliferous monstrosity of 

 the Garden Rose. From the centre of the flower proceeded a 

 second peduncle, bearing at its apex an additional flower-bud. 

 The petals of the larger (normal) flower were much elongated 

 and embraced the additional peduncle. Mr. M'Lellan stated that 

 the parent bush, which is trained up the side of a house in 

 Perthshire, had this season borne only the monstrosity ex- 

 hibited; but that he had frequently seen such abnormal forms 

 in the flowers of the Boursault Rose. In the course of some 

 discussion on the tendency in the rose to produce abnormal 

 flowers, it was remarked that while such aberrations are much 

 more abundant in some seasons than in others, in many cases 

 they are observed on the same bush in successive years, 

 showing that their presence is frecjuently due to some change 

 in the constitutional character of the bush. 



The following papers were read: — "Biological Notes," with 

 illustrative specimens, by Mr. Peter Cameron ; * " The Decapod 

 and Schizopod Crustacea of the Firth of Clyde," by Mr. J. R.

The Chairman referred in feeling terms to the loss which 

 the Society has sustained in the death of Mr. M. C. Dutf, the 

 Treasurer; and it was unanimously resolved that a notice of 

 Mr. Duff's death should be recorded in the minutes, and an 

 extract therefrom forwarded to the relatives of the deceased, 

 with an expression of the sympathy of the Members of the 

 Society with them in their bereavement. 



IN MEMORIAM—M. C. Duff. 

 MUNGO Campbell Dup^f was born in Edinburgh, but received 

 his education and business training in Glasgow. Along with 

 the other members of the Glasgow Society of Field Naturalists, 

 he was admitted a member of the Natural History Society of 

 Glasgow on the amalgamation of the two Societies at the 

 closing meeting of the Session 1878-79. While making no pre- 

 tensions to scientific attainments in any department of Natural 

 History, Mr. Duff took a keen interest in all the work of the 

 Society, contributing to the meetings by the exhibition of 

 specimens in various branches. His special leaning was to 

 Cryptogamic Botany, in one section of which — viz., the Ferns 

 —he had acquired, and cultivated in his greenhouse, a complete 

 collection of the British species, with many rare and interesting
