* When two or more species of Pferopus occur together in one place, thev 

 are generally conspicuously different in size. The length of the forearm of a 

 specimen to be determined, together with the precise locality given on its label, 

 will therefore in most cases help the non-specialist to an easier and quicker 

 identification than the necessardy long and complicated dichotomic " Key " 

 to the species (pp. 90-97). To serve sich purpose is the sole object of (he list 

 given above. It has bf-en compiled entirely from material exann'ned bv the 

 writer, but a reasonable individual variation in size, rather greater than 

 that actually observed, has been presupposed in those species of which tho 

 available material has not been considered large enough to show the irua 

 variation.
