SCIENTIFIC SOCIETIES. 279 



Mr. Howard Saunders exhibited and made remarks on a nearly white 

 skin of a Tiger obtained in Northern India by Major D. Robinson. Lieut.- 

 Col. Godwin Austin remarked that he had once, many years ago, come 

 across a white Tiger in India, but had failed to secure it. 



Mr. Saunders exhibited specimens of the eggs of a Gull, Larus maculi- 

 pennis, and of a Tern, Sterna trudeaui, from Argentina. 



Mr. Sclater read an extract from a letter received from Dr. Bolau, 

 describing two Sea Eagles living in the Zoological Garden, Hamburg, and 

 considered to be referable to Steller's Sea Eagle, Haliaetus pelagicus. One 

 of these, received from Corea, Mr. Sclater pointed out probably belonged to 

 the species described in the Society's 'Proceedings' by Taczanowski as 

 H. branickii. 



Dr. R. Bowdler Sharpe gave a short account of the proceedings of the 

 International Ornithological Congress recently held at Budapest, in which 

 he had taken part. 



Mr. G. A. Boulenger read a paper entitled " A Contribution to our 

 Knowledge of the Races of Rana esculenta and their Geographical 

 Distribution." Mr. Boulenger proposed to recognise four forms of this 

 widely-spread species of Frog, and pointed out the characters upon which 

 these races were based and the areas which they occupy. 



Mr. Oldfield Thomas read some notes on various species of Ungulates, 

 which he had made during a recent examination of the specimens of this 

 group of Mammals in the British Museum. 



Mr. Edgar A. Smith gave an account of a large collection of Marine 

 Shells from Aden. To this were added some remarks upon the relationship 

 of the Molluscan Fauna of the Red Sea with that of the Mediterranean. 

 A second communication from Mr. Smith contained descriptions of some 

 new species of Shells, based on examples obtained during the • Challenger ' 

 Expedition. 



Mr. H. A. Bryden read some notes on the present distribution of the 

 Giraffe south of the Zambesi, and made some remarks on the best means 

 on procuring living specimens of this animal for European collections. 



A communication was read from Messrs. Mole and Urich, containing 

 notes on some of the Reptiles of Trinidad, of which they had transmitted 

 living examples to the Society's Menagerie. 



Mr. F. E. Beddard read some additional notes upon the anatomy of 

 Hapalemur griseus made during a recent examination of two specimens of 

 this Lemur. 



Mr. E. B. Poulton, F.R.S., gave an account of an interesting example 

 of protective mimicry discovered by Mr. W. L. Sclater in British Guiana. 

 This was an immature form of an unknown species of Homopterous insect 

 of the family Membracida, which mimics the Cooshie Ant, CEcodoma 

 eephalotes. 



This meeting closed the session. — P. L. Sclater, Secretary.
