the one small specimen above alluded to. — In considering tlie affinities of 

 Udeììodon the author supported the opinion hitherto held, that it was only a 

 slightly modified Dicynodon, in which the teeth had failed to be developed. 

 The bones of Udenodon and Dicynodon^ taken together, were said to show 

 marked affinities with the Theriodonts and the Mammals, and less marked 

 affinities with the primitive forms [Pareiosaut-tis, Rhynchocephalians, Plesio- 

 saurs, and Chelonians), but only remote affinities with the higher reptiles. — 

 A communication was read from Mr. Oldfield Thomas, F.R.S., in which he 

 gave the history of the specimen of Rhinoceros lasiotis Sclater (which had 

 lived for 32 years in the Society's Gardens), and stated that he was of opi- 

 nion that it was not deserving of specific rank, but should be considered 

 rather as a subspecies of R. sumatrensis. The generic nomenclature of the 

 Rhinoceros was also examined, and it was proposed that the existing species 

 of this family should be divided into three generic divisons — Rhinoceros (to 

 include R. wiicornis and R. sondaicus) , Dicerorhiniis (to include R. sumatren- 

 sis and R. sumatrensis lasiotis), and Diceros (to include R. simtis and R. bicor- 

 nis). It was shown that, if it were found necessary to divide the species 

 R. simus and R. hicorins, the former, with its fossil allies, should bear the 

 name Coelodonta — Mr. G. A. Boulenger, F.R.S. , read a paper on a 

 small collection of Fishes from the Victoria Nyanza which had been made 

 by the order of Sir H. H. Johnston, K.C.B. Six species were enumerated 

 and remarked upon, two of which [Labeo victoriamis and Discognathus John- 

 stoni) were described as new. — Mr. F. E. Beddard, F.R.S. , described six 

 new species of Earthworms of the genus Benhamia from Tropical Africa. — 

 A communication was read from Mr. J. G. Millais, F.Z.S. , containing 

 some notes on the capture of a specimen of Bechstein's Bat ( Vespertilio Bech- 

 steini) in the neighbourhood of Henley-on-Thames. So far as was known, 

 this was only the second occurrence of this species recorded in Great Bri- 

 tain. — Mr. H. R. Hogg, F.Z.S., read a paper on the Australian and New- 

 Zealandian Spiders of the suborder Mygalomorphae. The author adopted the 

 nomenclature of M. Simon , and stated that of the seven subfamilies of this 

 suborder into which M. Simon had divided it, six were represented in Au- 

 stralia and New Zealand, the only absentee being the Paratropidinae of South 

 America. — P. L. Sclater, Secretary.

 Sitzung den 26. April 1901 : 



Gust. Swenander, Cand. Phil., demonstrierte mehrere Typen von 

 Vogelmagen und hob den Zusammenhang zwischen den Magentypen 

 und den verschiedenen Nahrungsmitteln der Vögel hervor. Besonders wurde 

 die Bedeutung von einem ausdehnbaren Drüsen- oder Muskelmagen und 

 vom Auftreten oder Fehlen eines »Schaltstückes« und eines Pylorus-Magens 

 aus einander gesetzt. Der Vortrag machte einen Theil der ausführlichen 

 Untersuchungen des Verf. über Vogelmagen aus, welche binnen kurzer Zeit 

 veröffentlicht werden.
