IV INTRODUCTION, 



4 species previously confounded with well-known forms 

 now sliowu to be distinct — Rona vicina, R. granulosa, 

 Ixalus cinerascens, Biifo stomaticus. 

 2 species previously unknown to the Indian fauna but 



since added — Ixalus^ asper, Microhyla achatina. 

 6 species confined to the Malay Peninsula and not recorded 

 from British India proper — Rana hascheana, R.plicatella, 

 R. glandulosa, Bvfo penangensis, Phrynella pollicaris, 

 Megalophrys nasuta. 

 Making in all 147 species known from British India and 

 the Malay Peninsula; of these^ as is shown in the Table above, 

 the Indian Museum possesses specimens of 103, so that there 

 are still 44 species unrepresented in the Museum, and of these 

 desiderata a list is given below. 



The number of type specimens in the Museum amounts to 21, 

 of which 7 were described by Stoliczka, 5 by Anderson, 4 by 

 Blyth, 3 by myself, and 1 each by Blanford and Jerdon ; 

 a complete list of these, together with the references to the 

 original descriptions, will also be found below. 



The arrangement and nomenclature of this list are entirely 

 formed on Mr. Boulenger^s work in the British Museum Cata- 

 logues and the Reptiles and Batrachia in the ' Fauna of 

 British India ' series, and I have to ofl'er him further my very 

 best thanks for a great deal of help in identifying many obscure 

 specimens and allowing me full access to all the British 

 Museum Collections. 



The descri]jtions of several new species and certain novel 

 facts in geographical distribution and synonymy will be found 

 in a paper published in the Proc. Zool. Soc. for 1892, p. 341, 

 which is referred to throughout the list. 



The principal donors of the Batrachia in the Indian Museum 

 are: — Dr. F. Stoliczka, Dr. J. Anderson, Dr. T. C. Jerdon, and 

 Mr. W. T. Blanford from all parts of India ; Col. Beddome and 

 Mr. W. M. Daly from South India; Mr. Gammie from the 

 Darjecling District, and Mr. W. Theobald from Burma ; and, 

 finally, Capt. J. Butler and Messrs. S. E. Peal and J. H. Boui-ne 

 from Assam.
