1890.] Address. 107 



Batrachia. The occurrence of Crocodilus porosns in the neighbourhood of 

 almost all the islands is noted. Of the snakes, Tropidonotiis clirysargus, 

 from Elphinstone Island, and Dipsas carinata, from Sullivan Island, are 

 apparently new to the Tenasserim Province. Twenty specimens of 

 Bana dorice, recently described by Boulenger from North Tenasserim, 

 were found on the Islands, and it is probably widely distributed over 

 the province of Tenasserim. 



The new edition of Mr. Boulenger's " Catalogue of the Chelonians, 

 Rhynchocephalians and Crocodiles in the British Museum (N. H.)" is 

 mainly devoted to the Chelonians and will be of great use to students of 

 existing and fossil forms. 



Mr. Boulenger has also described, in the An7i. Mns. Civic, di Storia 

 Naturale di Genova, the Beptilia obtained in Burma, north of Tenasserim, 

 by Signer L. Fea, completing the lists of the herpetological collections. 

 The new forms described are Simotes torquatus, from Bhamo ; S. plani- 

 ceps, from Minhla; new genus Gyclophiops. — G. dorice, from the Kakhyen 

 Hills ; Dendrophis subocidaris, from Bhamo ; Pareas andersonii, from 

 Bhamo and the Kakhyien Hills A new genus Azemiops — A. fece, 

 from the Kakhiea Hills, is very interesting, as its nearest ally is Dino- 

 dipsas, a snake described by Peters from I'aerto Cabello, in Venezuela. 



In the Proceedings of the Zoological Society, the same author has 

 published a paper on the species of Frogs confounded under the name 

 of BhacopJiorits maculatus : he shows that several Ceylonese and Indian 

 species have been included under that name and proposes to distinguish 

 as species the three following forms of which the character, synonomy 

 and distribution are given viz : — (1) Bhacophorus leucomystax, from 

 China, the Himalayas, and Burmese countries ; (2) B. 7naculatus, from 

 India and Ceylon and (.3) B. cruciger, confined to Ceylon. 



The British Museum Catalogue of Fossil Beptilia and Amphibia, 

 Part II., Ichthyopterygia and Sauropterygia, by our former member Mr. 

 R. Lydekker, contains several Indian and Asiatic forms, and is a valu- 

 able addition to knowledge. Mr. Lydekker's paper in our Journal, on 

 Chaibassia, has already been noticed. 



A very important and valuable paper is contributed by Surgeon 

 L. H. Waddell, M. B., to the Scientific Memoirs of the Medical Officers of 

 the Army in India, in which he gives the results of some most carefully 

 conducted enquiries into the effect of cobra-poison hypodermically in- 

 jected upon the snakes themselves from -which the poison had been 

 extracted, and also upon other cobras and other kinds of innocent snakes. 

 The experiments demonstrate unequivocally that the cobra is practically, 

 if not wholly, insusceptible to the toxic action of its own venom, whether 

 from the same snake or from another.
