Infraciliature of the planktonic protstomatid ciliate, Apsiktrata gracilis (Penard,1922)Foissner, Berger & Kohmann 1994. Morphologically quite similar to members of the genus Holophrya but lacking a "dorsal brush". The anterior apical cytostome and its circumoral dikinetids is seen here.There is a long caudal cilium in vivo (only its basal body is seen here at the posterior pole). Collected from a freshwater pond near Boise, Idaho. Silver carbonate stain (see Foissner, W. Europ. J. Protistol., 27:313-330;1991). Brightfield
