ABSTRACT OF THE PROOEl^^DliNGS 



OF THE 



ZOOLOGICAL SOCIETY OF LONDON; 



November 23rd, 1915. 



Dr. A. Smith Woodward, F.R.S., Vice-President, 

 in the Chair. 



The Minutes of the last Scientific Meeting were confirmed. 



Mr. R. W. Harold Row, B.Sc, F.Z.S., exhibited photographs 

 of an interesting abnormal Frog, in which both posterior linabs 

 lacked the hallux, though the calcar, or prehallux, was present on 

 each side. The characteristic structure of the digits still existing 

 clearly proved that the missing toe was the hallux, and dissection 

 showed that there was no trace of it internally. All the other 

 four digits were perfectly normal. 



Prof. Arthur Dendy, D.Sc, F.R.S., F.Z.S., read a paper on a 

 collection of Land-Planarians made by members of the British 

 Association in West Australia and Tasmania. Three species were 

 obtained in West Australia, all of which proved to_ be new, and 

 of six species collected in Tasmania, two were described as new. 



Mr. G. A. BoULENGER, F.R.S., F.Z.S., gave an account of two 

 papers containing lists of the Snakes of East Africa and Ifyassa- 

 land, and of North-east Africa and Socotra, with keys to the' 

 identification of the genera and species. 



* This Abstract is published by the Society at its offices, Zoological Gardens,
