Notes
Surface structures of the bud of Discophrya guilcherae Matthes 1954 have been investigated by scanning electron microscopy and compared with results gained by light- and interference-contrast microscopy of living specimens. The shape of the large bud (200x80 µm) is very flat and sole-like when viewed from above. Locomotoric cilia cover the ventral surface with exclusion of the scopuloid dot and a triangular, cilia-free area. The latter is limited to the back end by a striking row of large pores situated on top of a curved bulge. This structure is compared with the pellicular pores -covering the whole cell surface- and with related structures of other suctorians. The dorsal surface is nearly free of cilia with the exception of a single longitudinal row of stiff, long cilia ending in front of a cytoplasmic tip. The possible functions of this cinety, being obviously not actively motile are discussed.
