30th July, 1912. A dredging excursion to Poole Harbour and 

 Studland was arranged. Only three members 

 attended, and nothing of special importance was found. 



24th Aug., 1912. An excursion was planned to Swanage to work 

 the rock pools at Peveril Point. Owing to the 

 rough weather the steamboats were unable to run, and the excur- 

 sion had to be abandoned. 



25th Sept., 1912. The Zoological Section joined the Botanical 

 Section in an excursion to the New Forest, and 

 visited Hatchett's Pond. A very pleasant time was spent by the 

 members who worked this splendid pond, and their labours were 

 well rewarded. Unfortunately, Mr. Waddington was prevented 

 from joining the expedition, but some of the collection was taken 

 to him, and we are greatly indebted to him for his report on the 

 finds, and for his notes on other work during the year, 1912. 



Mr. Omer Cooper also worked out very carefully his collection 

 from Hatchett's Pond, and has given the following list of his 

 finds : — 



Entomostraca. 

 Suborder. Cladocera. 

 Sida crystallina 

 Ceriodaphnia reticulata 

 Simocephalus vetulus 

 Bosmina longirostris 

 Eurycercus lamellatus 

 Alona reticulata 

 Peracantha truncata 



Mr. Waddington, F.L.S., writes: — "The portion of the 

 gatherings from Hatchett T s Pond and the neighbouring pools, 

 which were handed to me contained much interesting material. 

 In addition to the objects usually found in this locality, there were 

 many Algas, notably, the two forms, Gloeotrichia pisum and 

 Glceotrichia natans. 



Among the Infusoria were some large masses of Ophrydium 

 versatile, which is somewhat rare. The pools abound with 

 Entomostraca. A single specimen of Graptoleberis testudinaria 

 was found. This adheres very firmly by the ventral surface, and 

 is removed with difficulty. It Is easily overlooked. Three or four 

 species of Planarians were abundant, many containg ova. 



In a gathering from Ringwood, brought by Mr. J. W. 

 Chaffey, were many varieties of unicellular algae, also the 

 Entomostracan, Scapholeberis mucronata. Mr. Chaffey has again 

 found the rare Rotifer Pedalion minim. 



Probably the most interesting find of the year was that of 

 Chirocephalus diaphanas. This, when found, is usually " made 

 a note of." It was met with after long and patient search by Mr. 

 A. J. Rainer in three or four pools some miles from Christchurch.
