MARINE PROTOZOA FROM WOODS HOLE.

Bodo globosus Stein. Fig. 13. 
The body during movement is globular or ovoid, without any anterior process. The trailing 
flagellum is invariably much longer than the vibratory one. The contractile vacuole lies in the ante- 
rior half of the body. Solid food particles are taken in near base of flagella. 
Length of body 9 to 12//; diameter 8 to 11 //. Common. 
Bodo eaudatus (Duj.) Stein. Fig. 14. 
Synonyms: Amphimonas eaudatus Duj.; Diplomastix caudata Kent. 
The body is variable in shape, but usually flattened and pointed posteriorly. An anterior process 
is almost always present, and below this the flagella are inserted in a minute depression. The con- 
tractile vacuole is close to the base of the flagella. The flagella are about the same size, the anterior 
one usually somewhat longer. Common. Length 12 to 18//. 
This species was seen by Peck ’95 and described as a small flagellate.

Genus OXYRRHIS Duj. 
(Kent ’81; Biltschli '86; Klebs '92; Sennl900.) 
Medium-sized forms, somewhat oval in shape, with a rounded posterior end. The anterior end 
is continued dorsally in a somewhat attenuate pointed process. At the base of this process is a large 
cavity or funnel, on the dorsal wall of which, or on a projection from this wall, are two equal-size 
flagella. When at rest, the flagella are directed backwards. The nucleus is central. In moving, the 
posterior end is invariably in advance. This genus is exceptional among Mastigophora in that division 
is transverse instead of longitudinal.

With the characters of the genus. Contractile vacuole not seen. Length 28 to 40//. 
Genus ASTASIA Ehr. 
Flagellates with one flagellum, a spindle-form body and a high degree of plasticity, the contour 
constantly changing. A distinct, usually striped cuticle is invariably present. “Eve-spots” are 
absent. Fresh and salt water.
