Figure 103 represents the head of an aegipan in the British Museum showing a supernumerary auricle.

As a rule, supernumerary auricles are preauricular appendages.

Warner, in a report of the examination of 50,000 children, quoted by Ballantyne, describes 33 with supernumerary auricles, represented by sessile or pedunculated outgrowths in front of the tragus.

They are more commonly unilateral, always congenital, and can be easily removed, giving rise to no unpleasant symptoms.

They have a soft and elastic consistency, and are usually composed of a hyaline or reticular cartilaginous axis covered with connective or adipose tissue and skin bearing fine hairs; sometimes both cartilage and fat are absent.
