iqib.j Thomas: Some Malayan Microchiroptern. 3 



A rare bat, not hitherto received at the British Museum. 

 These specimens quite agree with Dobson's description of the 

 type from Tenasserim. A rather strongly maikeri naked pad 

 or wart just under the symphysis mcnti is not mentioned by the 

 describer, but is present in all the specimens.

 Scotophilus castaneus, Bonhote. P. Z. S. 1900. p. 142 ; id. 



number 617. 



Similar in general characters to typical M. peytoni. 

 Wrought. & Ryley,* of Kanara, but the forearm, metacarpals 

 and hind legs shorter. 



Colour uniform dark brown, darker than in true peytoni, 

 the tips of the hairs with scarcely an)- of the lighter wash 

 evident in every specimen of peytoni. 



Dimensions of the type, the italicized measurements 

 taken in the flesh :— 



Forearm 39.5 (45 in peytoni). 



Head and body, 53; tail, 35; ear, 15. Third finger, 

 metacarpus 36 (42 in peytoni) first phalanx 15.7 (16). Lower 

 leg and hindfoot with claw 23.3 (28). 



Skull, greatest length 16.5; basi-sinual length 12.6; front 

 of canine to back of wt 3 6.5. 



Habitat and Type, as above. 



This fine Myotis is so essentially similar to the S. Indian 

 M. peytoni, the skulls being practically indistinguishable, that 

 I only consider it as representing a local subspecies, in spite 

 of the marked difference in the length of the limb-bones. 

 Curiously enough, while the metacarpus is so much shorter 

 than in true peytoni, the first phalanx of the third finger is of 

 about the same length in the new forms.
