Description of Climacocylis scalaroidesTintinnid ciliate, lorica is very delicate and transparent. It is narrower and usually smaller than the preceding species. The spiral band is restricted to the upper part and may show from five to ten turns. Of these the lowest one or two are usually flat, but the rest are produced into a rounded ridge. The lorica may be cylindrical or may narrow a little towards the aboral end, but this is partially closed by a great thickening in the wall. There are almost always one or, more frequently, two triangular prolongations from one side of the aboral end. The secondary structure is similar to that of the preceding species and the meshes become very large in the caudal prolongations. Length 90-224 microns, diameter at mouth 30-37 microns, 17 spiral turns.
