248 PROCEEDINGS OF THE 



Messrs. F. J. Cheshire, Henry Edwards, and H. D. Rawson 

 were balloted for and duly elected members of the Club. 



The List of Donations to the Club was read and the thanks of 

 the members voted to the donors. 



Mr. C. D. Soar, F.R.M.S., read a note describing two new 

 species of water-mites. These were Arrhenurus Scourfeldi sp. 

 now and Acercus longitarsus sp. nov.. The first was taken by 

 Mr. Scourfield in Cornwall, in fresh water, in the autumn of 

 1912. It belongs to the sub-genus Megalurus, female unknown. 

 The new species of Acercus is named from the unusually long 

 tarsi found in the fourth pair of legs. Locality, South .Devon- 

 shire, female unknown. Mr. Soar also said that Mr. Williamson, 

 F.R.S.E., in working out the material on the genus Sperchon 

 had found two species new to Britain, and two that have only 

 been recorded for Ireland. These were Sperchon clupeifer Pier, 

 sub-genus Hispidosperchon, from Oban and Norfolk Broads. 

 Sperchon tenuabllis Koen, sub-genus Hispidosperchon, from 

 Oban. Recorded by Halbertin Clare Island Survey for Ireland. 

 Sperchon papillosus, Sig. Thor, sub-genus Squamosus, Oban, 

 recorded by Halbert for Ireland ; and Sperchon Thienemanni, 

 Koen, sub-genus Rugosa, from Derbyshire. Drawings of the 

 two new species were exhibited. 



The Chairman said they were all deeply indebted to Mr. Soar 

 for bringing these new species of Hydrachnidae before them, and 

 they would be able to appreciate the value of the paper more 

 when in print. The drawings in illustration of the species 

 described were very tine indeed. 



The thanks of the meeting were unanimously voted to Mr. Soar 

 for his paper. 



In the absence of the author, the Hon. Treasurer, Mr. F. J. 

 Perks, read a paper on " The Collection and Preservation of the 

 Hydroida," by Mr. G. T. Harris, of Sidmouth, a former member 

 of the Club. The author said that the Hydroida are too well 

 known as affording both beautiful and interesting objects to need 

 any eulogy at his hands. Bearing in mind that this paper is 

 written more for the help of the novice than as a communication 

 offering original matter, the writer wished to safeguard himself 

 from any charge of carelessness by warning the uninitiated that 

 collecting, say, rotifers and collecting hydroids are two totally and 

 very dissimilar things.
