IHE HEAD OF THE BEE, 
attached to the mentum, and can be drawn in and 
extended by two muscles called the retractor and pro- 
tractor linguce. It is covered by a sheath on which 
are arranged rows of hairs (Fig. 12, r). These Hyatt 
(70) found to be short and triangular in shape at 
the base, long and spiny about the middle, smaller 
and more flexible near the apex. 
iVmongst these hairs there is a row of minute pits, 
with a central papilla (Fig. 12,//), which have been 
described by Leydig ( 96 ), and 
Kraepelin (82), who suppose them 
to be organs of taste. 
At the end is what is called the 
spoon (Figs. 10 and 12, or houton 
of Reaumur (139), circular and con- 
cave, with a row of pale clavate hairs 
(Fig. 12, and Fig. 5, e) along the 
edge, and short hooked hairs on 
the inside, which Kraepelin also 
considers are for tasting, as they carry 
a minute opening at their ends. 
At the narrowest part of the 
tongue, just above the spoon, there is a fringe of guard 
hairs (Figs. 12, /, and 14, b, /). 
By referring to the section (Fig. 14, a), it will be 
seen that the sheath {a) passes round the tongue to the 
under side and is continued by a thin membrane {b) 
seen corrugated and covered with very short hairs. 
In Fig. 10, /, this part of the tongue in seen unfolded. 
The membrane is continued to the rod (Fig. 14, 
A, r\ which runs the whole length of the tongue and
