Mr. F. E. Beddakd, M.A., F.R.S., F.Z.S., Prosector to the 

 Society, read a paper " On two new Genera of Cestodes from 

 Mammals," based on specimens collected from animals in the 

 Society's Gardens, 



A paper was received from Miss Ruth Harrison, entitled 

 " Some Madreporaria from the Persian Gulf ; with a Note on the 

 Memoir and some Further Notes on Pyrophyllia injlata by 

 Sydney J. Hiokson, M.A., D.Sc, F.R.S., F.Z.S." This memoir 

 dealt with a collection of corals made by Mr. F. W. Townsend, 

 the most interesting species obtained being P. inflata and Tre- 

 vtiatotrochus zelandice, the latter of which was identical with the 

 specimens from Cook's Straits, New Zealand, described as Gono- 

 cyathus zelandioi by Prof. Martin Duncan. A new species of 

 Heterocyathus was described, and Professor Hickson appended a 

 note on the affinities of Pyrophyllia. 



Mr. 0. L. BouLENGER, M.A., F.Z.S., contributed a paper " On 

 Variation in the Medusa of Moerisia lyonsi" based on an exami- 

 nation of 400 specimens. Nearly 14 per cent, of these were 

 found to be abnormal, and to fall naturally into two well-marked 

 groups containing completely distinct phenomena. The author 

 discussed these sepai'ately and in detail, and stated that he knew 

 of no form in which such a variety of abnormalities occurred as 

 in Moerisia. 



Mr. Cyril Crossland, F.Z.S. , presented two papers, entitled 

 " The Marginal Processes of Lamellibranch Shells " and " Warn- 

 ing Coloration in a Nudibranch Molhxsc and in a Chameleon." 

 As a pendent to the second of these Sir Charles Eliot, K.C.M.G., 

 C.B., F.Z.S., contributed a paper on " Chromodorids from the 

 Red Sea collected and figured by Mr. Crossland," containing an 

 account of three species of Chromodoris, which were noteworthy 

 as being varieties of known species or forms hitherto inipei-fectly 

 desciubed.
