One example only was captured as it emerged with some 
specimens of Rhénolophus luctus (Temm.) from the mouth of a 
eave. 
I have mueh pleasure in naming this species, which by 
its very large and complicated nose-leaf differs from all 
other forms known to me, after Mr. E. A. W. Cox, of the 
Sarawak Service, to whom I am indebted for the unique 
specimen,
