The labium (Fig. 15) is not described by the name under 

 lip, as its base forms the floor of the mouth, and its tip the 

 tongue. The base is usually broad, and is called the men- 

 tum, and from this extends the tongue (Fig. 15, a) or ligula.

On either side, near the junction of the ligula and mentum, 

 arises a jointed organ rarely absent, called the labial palpus 

 (Fig. 6, k7c), or, together, the labial palpi. Just within the 

 angle formed by these latter and the ligula arise the para,- 

 glosase (Fig. 15, d), one on either side. These are often 

 wanting.
