Notes

The infraciliature of Gastrostyla steinii (Ciliophora, Hypotrichida) has been revealed utilizing special protargol staining procedures. A variety of fibrous structures extends from each of the ventral cirri and a separate array of fibers is associated with the adoral zone of membranelles. The patterns these fibers display are in many ways similar to those shown for other hypotrich ciliates, particularly those containing marginal rows of cirri. Some consideration of function for these infraciliary components is presented. The strain of G. steinii studied has some plasticity in the arrangement and number of ventral cirri. This phenomenon is discussed in terms of cirral polymorphism of other hypotrichs and some hypothetical considerations specifically for G. steinii.
