SO.ME KONKAN BATS. 723 



As already said, P. m/mus is markedly smaller than P. ahramus. The 

 dimensions of 7 specimens, unfortunately all males, collected by me are 

 as follows : — 



Head and Body, Tail. Forearm.

Of seven skulls of P. ahramus (raa\Q\ six are 12*5 in greatest length 

 (the 7th is 12*3) ; while in greatest breadth, four are 7*5 and three are 

 7'o. The corresponding measurements for P. mimus give 11*5 as 

 greatest length in all cases ; while the greatest breadth is, 7 in three 

 cases and 6*5 in two others (two skulls are missing). 



The first two specimens in the above table were obtained in the 

 Mandvi Taluka of Surat (north of the Tapti River), while the rest were 

 taken at various places (Mheskatri, Jhaura. &c.) in the north-west 

 corner of the Dangs. 



As far as can be judged from so small a collection, P. mimus is a bat 

 of the heavy jungles. It resembles P. ahramus in its habits, as it does in 

 shape, but it does not ' represent ' it, to the exclusion of the latter, for 

 I have shot both at the same place on the same evening. 



The genus Hesperoptenus is represented in our area by one of its 

 two species only. 



Hesperoptenus tickelli, Blyth (No. J 91). 



This appears to be a comparatively rare bat. I obtained only two 

 specimens, both males, one in the centre of the Surat and the other of 

 the Thana District. 



Either this is a bat which varies immensely in size or the measure- 

 ments quoted by Blanford are those of an immature specimen.

The last of these is certainly immature. 



Hesperoptenus appears on the wing much later than the Pip/strelles. 

 Both specimens I got when it was almost dark. Perhaps this and not 

 its rareness is answerable for the few specimens I obtained.
