John Scoiiler, M.D., LL.D., F.L.S., President, in the chair. 

 The following gentlemen were elected office-bearers for the 

 session: — John Scouler, M.D., LL.D., F.L.S., President; Hugh 

 Colquhoun, M.D., Vice-President; Robert Gray, Secretary; Thomas 

 Chapman, Treasurer; Thomas S. Hutcheson, Librarian; Messrs 

 James Thomson, David Robertson, and Donald Dewar, M.D., 

 Members of Council. 



SPECIMENS EXHIBITED. 



Mr David Robertson drew the attention of the meeting to a 

 series of star-fishes he had laid on the table, selected from various 

 species, and presenting abnormal appearances in the number of 

 rays, and their reproduction when lost by accident. One of the 

 specimens of Uraster rubens showed a curious feature in having a 

 newly developed limb bifurcated. 



Mr Robertson likewise contributed the following notes on two 

 specimens exhibited: — 



Acantholeheris curvirostris (Miiller). — This crustacean was gath- 

 ered in a small tarn on the larger Cumbrae, the bottom of which 

 was covered with confervse and moss. It seems to be fond of the 

 shelter of weeds, though it is often seen actively swimming with a 

 jerking motion, occasionally mounting to the surface of the water, 

 and then dropping slowly to the bottom, rarely making any 

 motion when sinking, except when disturbed. I have also cap- 

 tured it in Arran, above Whiting Bay. 



Asterina gibhosa (Pennant). — Found in a rock pool, adhering to 

 the under side of stones, in the smaller Cumbrae, the only locality 

 I am aware of in the Firth of Clyde.
