Thyroptera. Jimenez de la Espada (see above, p. 3) relates his observa- 
tions of these Bats in detail. The sucking-cups consist of a coriaceous disk ; 
they are little hemispheres, hollow, flexible, and extremely movable, on 
the first phalanges of the thumbs of the wings and near the heels on the 
soles of the feet. They were used by the animal to fasten itself to the fingers, 
as it tried to bite, producing the same feeling as a key or thimble when ap- 
plied to the tongue after sucking out the air. These cups are deep, mem- 
branaceous on the edge, fleshy in the centre, those on the wings larger than 
those on the feet. The muscular arrangement is such as to allow the animal 
to vary the diameter of the. organ; and by their means the animals attached 
themselves to the sides of the box in which they were kept, although when 
sleeping they suspended themselves by the claws like other Bats.
