Dr. F. E. Beddard, M.A., F.R.S., F.Z.S., Prosector to the 

 Society, read a paper on the anatomy and systematic arrangement 

 of the Cestoidea, in which he described a new genus and species 

 of Tapewoi-ms from the Double-striped Thicknee {CEdicnemus 

 histriatus). 



Dr. F. A. Bather, M.A., F.R.S., F.Z.S. , read a paper entitled 

 " The Fossil Crinoids referred to Hypocrinus Beyrich." The 

 two specimens of Hyiiocrhius schneidei'i Beyr. described by Beyrich 

 and Rothpletz respectively are redescribed and refigured. The 

 structure of the genus is shown to agree with that of the Devonian 

 family Gasterocomidse, the content of which is discussed ; but it 

 is suggested that in this case and in that of " Lecythiocrinus " 

 adamsi the distinctive features may have been independently 

 acquired. 



The holotype of Hypocrimis 2nri/ormis Rothpletz is redescribed 

 and refigured, and proved to be no Hypocrimos. It is thought to 

 be a highly modified descendant of the Taxocrinidfe, by way of 

 such a genus as Cydonocrinus. The left posterior i-adial appears 

 to have borne a large arm, but the other arms are more or less 

 atrophied, and the right posterior radial has almost disappeared. 



A paper on " Batrachiderpeton lineatum Hancock & Atthey, 

 a Coal-Measure Stegocephalian," communicated by Prof. J. P. 

 Hill, D.Sc, F.R.S., F.Z.S., was read by Mr. D. M. S. Watson, 

 M.Sc. It contained the description of the skull, lower jaw, and 

 pectoral girdle of this species, based on a series of specimens in 

 the Newcastle Museum, derived from the Low Main Seam of 

 Newsham Colliery, 



A paper, communicated by Dr. C. W. Andrews, F.R.S., F.Z.S., 



was received from Mr. R. W. Palmer, M.Sc, entitled " The 

 Brain and Brain-Case of a Fossil Ungulate of the Genus 

 Anoplotherium" in which a cranium from the Phosphorites 

 of Quercy, together with an exceptionally perfect and well- 

 marked brain-cast obtained from it, were described from material 

 in the British Mviseum collections.
