M. dauhentoni, whose occurrence in India is extremely doubtful, and 

 he gives separate headings to L. longi^xs and L. megalo^^us, which I 

 "believe to be identical. 



On comparing a co-type of the first of these with the actual type 

 of the second (B. M.Nos. 76. 3. 10. 4 and 73. 4. 16. 1), I find 

 that they are similar in all respects and should undoubtedly be 

 united. The name should be L. loiujiiDes, Dobs., as I agree with 

 Blanford that Blyth's Myotis theohaldi must be set aside as in- 

 determinable. 



The types of the latter are lost, and the measurement of the foot, 

 " 7 jn." does not agree with that in L. longipes, nor, without 

 knowledge of how it was taken, or with what exactitude, can it be 

 fitted to any other species. 



The Indian species of Leuconoe may be distinguished by their 

 skulls as follows : — 



A. Skull length 16 mm. or more. Breadth 



of brain case over 8 mm. 

 a . Middle premolar crushed inwards, less 



than one-third the size of p\ 



Ceylon, Java. ... ... ... L. hasselti. 



h. Middle premolar not or little crushed 



inwards, at least two-thirds the size 



of p\ 

 a^. Larger, brain case less swollen, p.^ 



about two-thirds the area of p.' 



Bomba5^ ... ... ... ... L. ijeslnva. 



If. Smaller, brain case more swollen. 



p" nearly equal to p\ Tibet, Formosa. L. taiwanensis. 



B. Skull length 15 mm.. Breadth of brain 



case 7'4 mm. Andamans. ... ... L. dryas. 



C. Skull length 14 mm. Breadth of brain 



case 7 mm. Kashmir. ... ... L. longifes. 



Leuconoe hasselti, Temm. 



Six skins from Kokopeetchie, Eastern Province, and A' Pura, 

 Northern Central Province, Ceylon, obtained for the Sui-vey by 

 Major Mayor are indistinguishable from authentic Javan specimens 

 of L. hasselti in the British Meseum. 



There is also in the Museum an immature spirit specimen obtain- 

 ed in Cejdon by Dr. Ontdaatje in 1888. 



Leuconoe loesliu-a, sp. n, 



A medium sized dark coloured species allied to L. Jiorsfieldi. Size 

 rather larger than in horsfieldi. Fur fine and velvety ; hairs on 

 shoulders rather less than 7 mm. in leng-th; on hind back
