can be divided into two functional passageways, each contammg one
MLDB complex, by interlocking the anterior wall of the spiracular cavity
with the membranous nasal septum, in a sort of tongue-and-groove arrangement. A proposal for how the MLDB complex might function will be the
subject for discussion later in this chapter.
At the center of each sound generation complex is a pair of small, oblong
fatty structures contained within a pair of tough internal lips, the monkey
