The monokinetids (single somatic basal bodies) of Coleps hirtus bear an anteriorly directed striated fibrous kinetodesmal fiber and a posteriorly directed ribbon of postciliary microtubules that arise from the posterior side of each basal body. Both pass to the same side of the row of basal bodies. Transverse microtubules arise from the anterior side of the basal body and pass to the other side of the row of basal bodies. These structures presumably give support to the twisting movements of the beating cilium. Standard glutaraldehyde fixation followed by osmium tetroxide, dehydrated in alcohol and embedded in an epoxy resin. Microtome sections were prepared at approximately 75nm thickness. TEM taken on 5/23/69 by R. Allen with Philips 300 operating at 60kV. Neg. 14,800X. The negative was printed to paper and the image was scanned with a flatbed scanner and 0.5?m bar added in Photoshop. This digitized image is available for qualitative analysis. A raw, unprocessed, high resolution version of this image (CIL:9015) is in the library and available for quantitative analysis.
