A Sixth Sense 



MOUTH 



THE SPECTACLED STENODERM. 



In this bat we find the sensitive organ not only in the ears and on the nose, but 

 the lips themselves are sensitive. Tills ^vA.uiiar arrangement enables it to seize its 

 food in the dark and to know exactly what it is without seeing it. 



THE TRIDENT BAT. 



This species has a very complicated organ which covers nearly the whole ot its 

 face, and is extremely sensitive. In this species it certainly cannot be claimed that 

 the sensitive organ of the sixth sense is a part of the ear.
