For the Marine Zoology Committee, Mr. Percy Davis, its 

 Secretary, stated that the report was necessarily very meagre on 

 account of the time being too short to allow of the minute examina- 

 tion of the numerous specimens dredged. With the assistance of 

 the boat's crew they were enabled to make four hauls with the 

 ordinary fisherman's trawl-net, which for that purpose proved 

 scarcely adequate to their requirements. The section hoped from 

 that day's experience to improve their tackle before another season. 

 He stated that the first haul resulted in the landing of a number of 

 fish — haddock, plaice, dab, and others, together with a few Echino- 

 dermata, but, singularly, an entire absence of Polyzoa. The second 

 haul produced fewer fish, more Crustaceans, together with Polyzoa 

 and a number of Zoophytes. The third was somewhat similar in 

 production as the second, the locality being almost the same. The 

 fourth and last, off Claughton Wyke, resulted somewhat disastrously 

 to the tackle. In the course of the dredge the trawl struck what 

 afterwards proved by the numerous anemones brought to the surface 

 to be a piece of wreckage. Notwithstanding the loss sustained by the 

 tearing of the net, they succeeded in landing an additional number 

 of species ; these would in due course be named and catalogued. 

 A vote of thanks to the chairman concluded the proceedings. — E.P.K.
