Notes on Fresh-water Ciliate Protozoa of India. 263 



Aspidisca lynceus Elirbg. 



Body very small, length about 2-4//,. In pond water from 

 Shalamar Gardens, among Sjnrogijra filaments, in August. Form 

 oval, posterior part broader, posterior end truncated, anterior end 

 pointed, with the peristomial cleft under its overlap. Five posterior 

 styles ; frontal styles distributed partly over the ventral surface of 

 the body, four on the central portion of the ventral surface, and 

 three near the anterior end. 



Dorsal surface smooth and not furrowed. Contractile vacuole 

 near the posterior end. Xucleus horse -shoe shaped. Locomotion 

 characteristic, swimming round and round, now from left to rights 

 now from right to left, sometimes stopping, and jumping or creep- 

 ins forward. 



PERITPJCHA. 



Family Yoeticellina Biitschli. 



Genus Scyphiclia Duj. 



Scyjphidia fromentelii S.K. (?). 



The specimens, which I have referred to this species with some 

 hesitation, were found in August attached to the carapace of 

 Daplmia, in pond Avater from Shalamar Gardens. Body small, 52 jjl 

 by 25yLt, form elongated, posterior end thinner and provided with a 

 rounded sucking cup. In a specimen detached from the host, 

 this posterior end was seen to contract independently as in sucking. 

 Body transversely wrinkled. Peristomial margin thickened and 

 reversible. Contractile vacuole anterior, near the middle of the 

 body. The form differed however from the description of the 

 type as recorded in Kent (IJf) in that the body was transversely 

 wrinkled, and the posterior extremity was not seen to be longi- 

 tudinally plicate. 



Genus Vorticella EhrbR. 



Vorticelkt campanula Ehrbg. 



In water from a pond in the Lawrence Gardens. On leaves of 

 Lemna, mostly on leaves which are dried up and brownish. October. 

 Social. Size 63 /t to 73 yu, being common. 



With characters of the type.
