SOME KONKAN BATS. 719 



on the hills north of the Tansu Lake, in the Thana Distriofc. This 

 seems to show that it is distributed through the two Districts, though 

 it is urduubtodly more common along the north bank ot the Tapti 

 River. 



My measurements taken from fresh specimens run rather larger than 

 those given by Blauford. They compare as follows : — 



Hea ! and Body. Tail. Forearm. 



Blanford's 44 31 35 



Average of 1 1 males ... 51*5 39 35 



Average of 5 females .. 51"8 38'8 35'2 



The minute outer incisor (see Plate, fig.U) distinguishes it at once from 

 all our other Pipistrelles. In fresh specimens this is so buried in the gum 

 that it is easily overlooked, and P. dormeri then seems to have only one 

 incisor on each side. The ashy tips of the hairs give this bat, especially 

 when freshly killed, a silvery lustre. This silvery look, which is especi- 

 ally noticeable on the breast and belly, is also very characteristic. 



P. dormeri is not a bat of the cities. It seems to prefer a large solitary 

 tree, standing in cultivation as a roosting place. Only a small number 

 share a tree, round which they hawk, rarely leaving its immediate neigh- 

 bourhood. They are on the wing shortly after sunset. 



Plpistrellus ceylonicus, Kelaart (^o. 18^). 

 The type specimen of this bat is lost, but I think Blanford was amply 

 justified in identifying it with P, md/cus, Dobson. At the same time I 

 think he is wrong in taking his measurements from the Wynaad speci- 

 men, which is too bleached to give any reliable indication of its real 

 colour, and at the same time, too damaged for identification by its 

 dentition. Blanford's measurements compare with mine as follows ( I 

 add Dobson's measurements of P. indicus) : — 



Head and Body. Tail. Forearm. 



Blanford 60 40 41-3 



Average of 4 males ... 50 37 37*5 



Average of 11 females. 51-5 39-5 37-5 



Dobson's P. enrf2CMs ...52-5 42*5 37-5 



The measurement of the forearm, being that of a bone, is the most 



important, for there can be only one way of measuring it. I may add 



that the British Museum has specimens from Ceylon (in spirits), which 



are undoubtedly the same species as mine, and which give the same 



forearm measurement.
