and ovary are normal; a large bladder is present. The foot glands 
are very small. 
The ganglion is fairly large and somewhat elongate. The re- 
trocerebral organ is limited to a ductless hemispherical sac en¬ 
closing the eye-spot at the posterior end of the ganglion; it is ap¬ 
parently filled with a liquid, very dark red pigment, almost 
opaque by transmitted light, so that the eye-spot is usually in¬ 
visible in the living animal; in preserved material the color of 
the sac clears up somewhat. 
Total length 300/*; toes 15/*; trophi 30/* long, 50/* wide. 
Lindia trwncata is widely distributed in swampy ponds and 
bogs, at times in very large numbers. 
This species is readily recognizable by the color of the body 
and the peculiar retrocerebral sac. Through the kindness of Dr. 
Jennings we have had the opportunity to study an abundance of 
preserved material of this species, which he collected around Ann 
Arbor, Michigan.

The body is elongate, spindle-shaped, and moderately slender, 
the greatest width being about one fourth of the total length. 
The integument is very flexible and the outline somewhat vari¬ 
able. The color of the animal is a light brownish red. 
The head segment is strongly rounded anteriorly; its width is 
about two thirds of the greatest width of the body and its length 
a little less. The neck segment is of nearly equal length and 
width. The anterior transverse folds are well marked. The ab¬ 
domen is very slightly larger at mid-length than at the anterior 
and posterior ends and terminates in a very broad, not very promi¬ 
nent, rounded tail. The foot has two joints, continuing the gen¬ 
eral outline of the body and marked by slight constrictions; the 
terminal joint is less than half the length of the anterior and car¬ 
ries the two short, bluntly conical toes, about one twenty fourth 
the length of the body; they are reduced to small tubules at the 
tips. 
The dorsal and lateral antennae are in the normal positions.
