Notes on Fresh-water Oiliate Protozoa of India. 265 



Epistylis articnlata From. 



Growing abundantly on all sides on a small spirally coiled 

 Gastropod shell (probably PlanorUs), on which it forms a white 

 fluffy mass ; found in pond water in Shalamar Gardens. Colonies 

 erect, height of colony about 0*6 mm. Pedicle dichotomous, 

 sparingly branched, striate longitudinally, articulate at one or two 

 intervals between each bifurcation, in which respect it differs from 

 E. plicatilis. Body form as in that species, but two zooids at 

 termination of each terminal stalk. 



Kent (14), in a note to the description of this species, observes 

 as follows : — " In shape the animalcules of this species appear to 

 closely resemble those of E. plicatilis, and it is a question whether 

 the chief point of difference cited by de Fromentel, that of the 

 articulation at distant intervals of the pedicle, is sufficient to 

 distinguish them, more especially as, in the last-named form. Stein 

 has remarked that old specimens are similarly jointed. No mention 

 is made as to the form assumed by the zooids when in a state of 

 contraction, which would have been.useful in the settlement of this 

 supposed identity, nor as to whether the species forms large or 

 small colonies." 



I am able to throw some light on this disputed point, having 

 observed the zooids in the contracted condition. The form assumed 

 by the contracted zooids is globular, the posterior part showing 

 transverse furrows as in E. plicatilis. The size of the colony, which 

 is considerably smaller than that of E. plicatilis, and the fact that 

 two zooids are perched at the termination of each stalk, along with 

 articulate character of tlie stalk, which is constant in one and a 

 rare feature in the other, will serve to distinguish between the two 

 species.

 Genus S2:)hserophrya CI. & Lachm. 

 Sphxrophrija p)usilla CI. & Lachm. 



Body very small, found parasitic in Paramecium caudatum 

 A specimen containing four young individuals was encountered in 

 October. Two individuals, provided with knobbed tentacles all 

 Tound, escaped under observation and began to swim freely.
