The negro races are noted for their large mouths and thick lips.

A negro called "Black Diamond," recently exhibited in Philadelphia, could put both his fists in his mouth.
Morgan reports two cases of congenital macrostoma accompanied by malformation of the auricles and by auricular appendages.

Van Duyse mentions congenital macrostoma with preauricular tumors and a dermoid of the eye.

Macrostoma is sometimes produced by lateral fissures.

In other cases this malformation is unilateral and the fissure ascends, in which instance the fissure may be accompanied by a fistula of the duct of Stensen.
