Abstract:
In 30 species of Mammals of varying body size (from rat to elephant), the form, dimensions and structure of the cartilage of the third eyelid were studied. The cartilage is a thin lamina concave in its corneal side, usually elongated in the oro-aboral direction. In the most species studied the outline of the cartilage may be inscribed in a triangle with a oral base, a dorsal margin, a ventral margin and an aboral apex. A study of stained sections revealed, in more than half of species, the presence of elastic fibres in the aboral part of cartilage; these fibres are particularly numerous, but non uniformly distributed, in the Equidae, lion and Suidae.
