Gynopterus brachyotis S. Muller. 



In van der Hoeven's Tijdschrift voor Natuurlijke Ge- 

 schiedenis en Physiologic, 1838-39, a small bat has been 

 described by Dr. S. Muller under the name Pachysoma bra- 

 chyotis. That author collected a large number of specimens , 

 all in the same locality , a deep lime-stone cave , on the 

 bank of the river Dewej , in the interior of Borneo : these 

 type specimens are in our Museum. 



Dobson (Catalogue, 1876) remarks under the head Gy- 

 nopterus brachyotus that an examination of the types of 

 brackyotus (lege brachyotis) in the Leyden Museum has 

 shown him that the Andaman-island variety (described by 

 him in 1873 as Gynopterus marginatus,\ax. andamanensis) 

 is identical with Müller's species. In the well-known Ca- 

 talogue published by Dobson in 1878, no word however, 

 concerning this species ; Gynopterus brachyotis Muller seems 

 to be entirely overlooked by that author. I am not aware that 

 the species has been recorded or mentioned after the year 

 1876, neither in the P. Z. S. nor in any other periodical , 

 so that I fear that it is on the way to disappear among
