Mr. E. G. BouLENGER, F.Z.S., presented a short paper by 

 Mr. G. A. BouLENGER, F.R.S., F.Z.S., containing some remarks 

 on the habits of British Frogs and Toads, for the information of 

 those who might feel inclined to carry out further observations on 

 the subject of the migrations of Amphibia as dealt with in a paper 

 recently read before the Society. The Common Toad was strongly 

 recommended as the most suitable Batrachian on which to 

 institute series of experiments on Distant Orientation. 



A paper on the " Milk-Dentition of the Ratel " v/as received 

 from Mr. R. Lydekker, in which he described an instance of 

 primitive features present in the milk-dentition being entirely 

 lost in the teeth of the permanent series. So far as he was aware, 

 no such atavistic feature had been hitherto recorded in the case 

 of any existing mammals.
