 Matthew P. Bell, Treasurer; John Grieve, M.D., Messrs John

SPECIMENS EXHIBITED. 



Mr David Eobertson exhibited a living specimen of Corystes 

 Cassivelaunus, which had been in his possession upwards of seven 

 months, during which time he had favourable opportunities of 

 observing its habits. In bringing these under the notice of the 

 society, he remarked that this crab, in burrowing into the sand, 

 lies buried for weeks without seeking to change, and that the 

 antennae clasp into each other when the creature is so situated, 

 forming a tube through which it breathes, and otherwise main- 

 tains a communication with the surface. Mr Eobertson also 

 stated that he had seen the ova cast up through this opening — the 

 inference being that the animal had placed it, by means of its 

 claws or pincers, within the influence of the current. Mr 

 Eobertson likewise exhibited specimens of Nereis bilineafa, and 

 made some remarks upon its habit of living in univalve shells, in 

 company with hermit crabs.
