ciiange) would have been necessitated, had it been otherwise, 

 beyond some additions to the distribution details, whicli are liere 

 furnitshed. The comparison and study for Vol. 2 have been 

 practically completed by Dr. Andersen, and I have his assurance 

 that for the Indian portion of his work, the Survey material has 

 been of invaluable assistance. Unfortunately the formulation and 

 publication of his results have been unavoidably postponed, and 

 they are not available to me in preparing- this summary. Dr. 

 Andersen however published in 1905 several papers on the 

 RHiNOLOPHin^ on which I have relied. 



Family II. — EiiiNOLOPHiDiE. 



Three Genera are represented which may be distinguished as 

 follows : — 



Key to the cjenera of the Rhinolopiiid^. 



A. — Firet toe with only two joints ; a dis- 

 tinct antitragus separated by a 

 notch from the outer margin of the 

 ear... 



B. — All toes with only two joints ; no notch 

 separating the antitragus from the 

 outer margin of the ear ... 



a. Anterior nose-leaf on horseshoe not 



divided in the middle 



b. Anterior nose-leaf divided into dis- 



tinct lappets 



Gen. I. — Rhinolophus. 



In 1905, Dr. Andersen published a paper (A. M. N. H. 7., xvi. 

 p. 648), in which he divided this genus into a number of groups, 

 and I think the most satisfactory aiTangement will be to take them 

 one at a time. They may be arranged in a key as follows : — 



Key to the groups of Rhinolophus. 



I. Rhixolophus.
