uglena rubra Hardy. 27 and 28, figure 55. 
Body large, cylindrical, anterior end rounded. Posterior end 
with short acute tip. Periplast finely spirally striated without 
punctuations. Color densely bright red. Length of body 115 
to 230 microns. 
I am indebted to Professor R. B. Wylie for bringing these 
specimens in formalin from Little Spirit Lake in August where 
they were abundant. This is not strictly an Iowa, record, as 
the lake is across the Minnesota. border line; but it is very likely 
that the species may be found in this state and the record is of 
interest. Walton regards this species as distinct from E. san- 
guinea. 
*Euglena new species. 29 and 30, figure 55. 
Body elongated, ribbon-like, habitually twisted into three 
areas. Conspicuously beaded in longitudinal rows, of which 
there are seven at the anterior end and only five at the poste- 
rior. Flagellum about half as long as the body. Nucleus oval, 
central, with a larger flattened paramylon body before and be- 
hind. Vacuole reservoir very large and circular, posterior to 
the large stigma. Cytopharynx plainly visible. Solitary. Color 
dense bright green, somewhat clearer at the tail. Size 190 mi- 
crons. 
This remarkable form was found in a vial of water from 
Fairport, Iowa, which had been standing in my laboratory for 
some weeks. It was large and active, apparently cramped for 
space under the cover glass. It would attach the tail to the slide 
and give the long body a twisted motion in a semicircle. The 
body was not strongly metabolic, but the raised beaded lines 
on the periplast were seen to move forward on one side and at 
the same time backward o.n the other. Professor Walton, prob- 
ably the foremost authority on the Euglenoidina, was kind 
enough to examine these drawings and notes, and writes : ‘ ‘ The 
probabilities are that a new form is represented.” 
*Trachelomonas oblong a punctuata Lemm. 31 to 33, figure 55. 
Shell oval, brown, dotted with punctae which show a spiral 
arrangement from the aboral end, but which from the side ap- 
pear to be irregularly scattered. In optical section the shell 
appears to be made up of small sections or to have pores (see 
figure). Stigma present; chloroleucites two, elongate; flagel- 
lum nearly as long as the body and thickened at the tip. Size 
23 microns.
