VII. Pedal Gland. 
(i) The pedal gland isa tubular body. The anterior portion 
is somewhat flattened from above downwards, while the posterior 
portion is triangular in transverse section. 
Minute structure.—The pedal gland agrees in minute structure 
with that in Azopos (Podangia) kempti, Ghosh, except in the 
following points :— 
(rt) In the present species there is a blood-sinus on the dorsal 
aspect of the lumen of the gland in the middle line. Its wall 
consists of longitudinal muscle fibres bounded on the outer side by 
a layer of connective tissue. 
(2) Owing to the interposition of a blood-sinus, the lumen of 
the gland comes to lie more or less in the centre and has become 
flattened out a little, instead of lying more towards the dorsal 
aspect and of being circular in transverse section as in A. (P.) 
kembit. ; 
(ii) The supra-pedal gland is a small tongue-shaped body lying 
between the proboscis sheath and the pedal gland, and opening 
into the exterior just above the aperture of the pedal gland. 
Minute structure.—The anterior portion forms a wide U-shaped 
cavity with the curve of the U continued in front to open into 
the exterior. The posterior two-thirds form a glandular mass, 
which consists of numerous lobules held together by connective 
tissue. Each lobule consists of a number of many-sided cells with 
spherical nuclei placed on one side. The ducts of these glands 
seem to open into the cavity of the body. On the outer aspects 
of the cavity, there are also numerous glands of similar structure 
with ordinary mucus-secreting cells in addition. The cavity of 
the gland is lined by a single layer of cubical cells. Immediately 
on the outer side of the epithelium is a thin layer of connective 
tissue which is prolonged outwards between the lobules.
