Fam. 4. MyRMECOPHAGID. 
Body covered with hair. Head conical, elongate ; mouth small. 
Edentata genuina, Cuvier, Oss. Foss. v. 97.

The ribs of the animals of this family are flat and more or less 
dilated on the outer side; they are most dilated in the Cyclothuri, 
where they are expanded nearly their whole length, and so much so 
that they overlap each other, and form a complete armour to the 
thoracic viscera. The figure given by Rapp agrees with the skele- 
tons in the British Museum. ‘The ribs of the skeleton of Myrme- 
cophaga, figured by Cuvier (Oss. Foss. v. t. 9) and Rapp (Edentata, 
t.6), are only dilated on the middle of the outer side, and not there 
to such an extent as in the above-named genus.

curved up.
