rubbed down so that the nerves had become exposed. The 

 animal must have suffered great pain, and this no doubt was the 

 cause of his dashing his head against the walls and bars of his 

 den in the violent manner he at times did. 



Mr. E. G, BouLENGER, F.Z.S., Curator of Reptiles, exhibited a 

 living specimen of the Salamander, Amblystoma tigrinum, which 

 he had obtained from an Axolotl placed in special conditions 

 with the object of forcing the metamorphosis.' 



Mr. D. Seth-Smith, F.Z.S., Curator of Birds, gave a lantern 

 demonstration of photographs of the young of Hemprich's Gull 

 [Larus hemjiriclii)^ the Black-necked Swan [Cygnus melano- 

 coryphus), and the White Stork [Ciconia cclba) which had been 

 hatched in the Society's Gardens during the present year. He 

 also showed slides of the nest, in a tree near the Apes' House, 

 made by the Orang-utan which escaped from its cage on 

 November 3rd, 1912. 



Mr. H. R. Hogg, M.A., F.Z.S., read a paper entitled " Some 

 Falkland Island Spiders," based on a small collection of Spiders 

 formed by Mr. Rupert Vallentin during a two years' stay in the 

 Falkland Islands. 



Of some of the species there were a fair number of specimens, 

 but they comprised only six species of Spiders and one of the 

 allied suborder Opilio. 



The species were all apparently new, but the genera were all 

 to be found either in Patagonia, Tierra del Fuego, or the islands 

 about Cape Horn. The ancestors of the Spiders might all have 

 been transported aerially at an early period and therefore afforded 

 no evidence for or against a former land-connection, but in the 

 event of the latter there should be many more species. The 

 Opilio might have been conveyed under the bark of floating trees. 



Mr. G. A. Boulenger, F.R.S., F.Z.S., read a short paper con- 

 taining the descriptions of three new Fishes which had been

 Dunkwa, Gold Coast, and presented by him to the British 

 Museum. 



A paper was communicated by Dr. H. Lyster Jameson, M.A., 

 Ph.D., F.Z.S., and Dr. William Nicoll, M.A., D.Sc, F.Z.S., 

 which contained an account of some parasites of the Scoter Duck 

 {CEdemia nigi'ci), and discussed their relation to the pearl-inducing 

 Trematode in the Edible Mussel (Myiilus edulis). 



A paper was received from Mr. F. F. Laiblaw, M.A., F.Z.S. , 

 dealing with some Dragonflies from Borneo belonging to the
