APPENDIX 



Ronget al. (1995) compared various affinity indices and found most 

 useful those by Otsuka [AI=C/(N,N 2 )" 2 ], Dice [AI=2C/(N,+N,)] 

 and Fager [AI=C/(N,N,)" 2 -1/(2(N,)" 2 ')]. In each formula N, is the 

 total number of genera of one fauna, N, is the number of genera of 

 another fauna and C is the number of genera common to both faunas, 

 supposing N, is larger than N . We have calculated the affinity 

 indices between the eight faunas by all three methods and Table 1 

 shows each index in the lower diagonal and their average in the 

 upper diagonal. Below are the lists of faunas used in the calculation 

 of affinity indices:
