the two highly muscular lobes 
or forks. The forks, on the other 
hand, appear under the lens to 
be perfectly smooth or provided 
with slight longitudinal wrinkles. 
The anterior forks are slender 
and acutely pointed and may lie 
side by side or become widely 
separated, according to the mus- 
cular contractions of the parts, 
Their basal portions are deeply 
pigmented, the dark pigment 
commonly extending for a little 
distance on the body of the tongue 
and sometimes well toward the 
tip of the fork, very much as in 
Anguis. The posterior lobes are 
rounded and provided with pa- 
pille directly continuous with 
those on the body of the tongue. 
The histological structure of the 
glands of the tongue of Anguts 
is described by v. Seiller (’91, 
pF en). 
The body of the tongue is at- 
tached to the floor of the mouth 
along its whole length, the lat- 
eral borders and anterior forks 
alone being free. 
The glottis is represented by 
an oval opening situated on a 
short elevation in the angle be- 
tween the two posterior lobes of 
the tongue. 
The mouth leads into the long, 
narrow esophagus, which passes 
gradually into the straight 
stomach. A sharp bend and 
narrow opening through a highly developed valve lie between stomach
