proboscis
n 1: the human nose (especially when it is large)
2: a long flexible snout as of an elephant [synonym: {proboscis},
{trunk}]

Proboscis \Pro*bos"cis\, n.; pl. {Proboscides}. [L. fr. Gr. ?; ?
before ? to feed, graze.]
1. (Zool.) A hollow organ or tube attached to the head, or
connected with the mouth, of various animals, and
generally used in taking food or drink; a snout; a trunk.
[1913 Webster]

Note: The proboscis of an elephant is a flexible muscular
elongation of the nose. The proboscis of insects is
usually a chitinous tube formed by the modified
maxill[ae], or by the labium. See Illusts. of
{Hemiptera} and {Lepidoptera}.
[1913 Webster]

2. (Zool.) By extension, applied to various tubelike mouth
organs of the lower animals that can be everted or
protruded.
[1913 Webster]

Note: The proboscis of annelids and of mollusks is usually a
portion of the pharynx that can be everted or
protruded. That of nemerteans is a special long
internal organ, not connected with the mouth, and not
used in feeding, but capable of being protruded from a
pore in the head. See Illust. in Appendix.
[1913 Webster]

3. The nose. [Jocose]
[1913 Webster]

{Proboscis monkey}. (Zool.) See {Kahau}.
[1913 Webster]
