Anterior part of buccal funnel ( b.f.) and base of haustellum; dorsal stabber forming 
a single groove; h.g. chitinous hinge of dental plate to buccal funnel. 
Anterior part of buccal funnel and festoons ( b.fs .). 
Anterior part of all the mouth-parts in the lumen of buccal region; note how the 
elements of the pharyngeal tube (ph.t.) are dorsally placed and how the elements of 
the sac tube (s.t.) embrace the stabbers; shreds of muscular (?) or connective (?) 
tissue still adhere to the elements of the sac tube. 
Showing how the elements of the sac tube act as guides to the stabbers. 
Region of divergence of food canal and stabber-sac; note the origins of the elements 
of the pharyngeal tube (o.ph.t.) and those of the sac tube ( o.s.t .). 
Anterior part of stabber-sac; the dorsal stabber is slightly distorted; the drawing 
below shows how one element overlaps the other and how the fusion of the dorsal 
and ventral elements of the ventral stabber is not perfect. 
Anterior extremity of sac floor groove ( s.f.gr .) somewhat distorted; note the lateral 
floor grooves {l.fl.gr.) and the insertion of the small anterior retractor muscles of 
the sac ( a.s.r.) and the widening of the sac at the region of the orifice of Pawlowsky’s 
glands. 
At region of the orifice of Pawlowsky’s glands—orifice not shown ( o.P.gl .); note the 
flanged edges of the sac floor groove, the tissue of the dorsal stabber separating it 
from the salivary pipe, the three dorsal grooves and the lumen of the ventral 
stabber. 
Similar to sect. 11; note anterior part of ventral portion of protractor muscle of the 
sac (“musculus digastricus” of Pawlowsky) (v.s.pr.); stabbers obliquely cut.
