MASTIGAMGBA RAMULOSA. 73 
' 2. Mastigameba ramulosa Kent. 
(Plate VI, fig. 6.) 
Mastigameba ramuloss Kent Man. Infus. I, pt. 2 (1880), 
p. 222, t. 1, ff. 19, 20. 
Body during active movement elongate-ovate, about 
one and a half times longer than broad, the entire 
peripheral surface bearing sub-equal branched pseudo- 
podal prolongations. Neither these nor the general 
surface of the body show secondary hispid pseudo- 
podia. The flagellum exceeds the body in length. 
The nucleus is sub-central and spherical; the con- 
tractile vesicle is located posteriorly. 
Dimensions: Length (according to Saville Kent) 
1-400" (63 p). 
In marsh-water, as yet only met with in Jersey 
(Kent). 
The description of this organism is from Kent’s 
‘Manual of the Infusoria.’ The author says that the 
conspicuously - branched character of the abundant 
pseudopodia serves to distinguish it readily from other 
forms, and communicates to it, as a whole, an aspect 
suggestive of a minute Nudibranch. Under any dis- 
turbing influence the little animal immediately con- 
tracts into a sub-spheroidal contour. It was observed 
that the granule-circulation, conspicuously indicated in 
the centre substance of the body, did not extend into 
the branched pseudopodia, nor were these appendages 
withdrawn entirely within the periphery at any time.
