observation was rather limited, but everything seemed to justify 
this conclusion. It was found among sphagnum so far decayed 
that no other animals were present which might serve as hosts; 
in fact, the collection was barren of animal life with the exception 
of a single specimen of Monostyla lunaris, two specimens of Le- 
padella rliomboides, and a few Protozoa. The animal is extremely 
sluggish, changing its outline very little at any time. The corona 
is normally extended, and the cilia are in constant motion, but they 
are so feeble and move so slowly that they appear to be of very little 
assistance in locomotion. As a matter of fact, we did not see 
the animal effect any considerable displacement at all; the ob¬ 
served motion was limited to rare and extremely slow bending 
movements. 
In spite of being non-parasitie, D. judayi agrees in so many 
respects with D deldgei and D. bucephalus that it must be in¬ 
cluded in this genus, and it also shows that Drilophaga is simply 
an otherwise fairly normal Notommatid genus which has lost 
all but the eircumapical ciliation. It is very unfortunate that 
no observations are at hand concerning the biology of this species, 
as it would be very interesting to know how an animal apparently 
so severely handicapped by nature manages to obtain its food 
and to avoid its enemies.

The body of this species is fairly slender, its greatest width 
being a little less than one fourth of the total length. The in¬ 
tegument is very flexible, and the animal is highly contractile. 
The entire body is very transparent. 
The head and neck segments are of nearly equal length and 
width, about two thirds the greatest width of the body. The an¬ 
terior transverse folds are not strongly marked. The abdomen 
increases very little in width for about two thirds of its length; 
from this point it tapers rather rapidly to the tail, which has a 
single, rather small, rounded median lobe. The foot has two 
short joints, the posterior much smaller than the basal joint. The 
toes are short, slender, conical, and slightly incurved; near the
