The following gentlemen were elected members of the society: — 

 Messrs John Manford, James Miller, William Couper, Joseph 

 Campbell, and Walter Gardner, 



SPECIMENS exhibited. 



Dr Scouler exhibited a specimen of Labrus trimaculatus, from 

 the Firth of Clyde, 



Mr David Robertson exhibited a curious and interesting annelid, 

 with its case, which he had dredged off Gourock. The tube, Hke 

 that of many built by allied species, was composed of fragmentary 

 pieces of shell, adhering together by a secretion of the animal ; but 

 on close comparison, this annelid, which Mr Robertson could not 

 in the meantime refer to any British species, appeared to have 

 selected these materials of a particular shape — being concave 

 on the one side, and convex on the other, and arranged longitu- 

 dinally, with each piece laid so as to cover the seam or joint of 

 the preceding layer, thereby presenting a device in which we could 

 recognize the soundest principles of architecture, as practised by 



animals of superior intelligence.
