14 posterior end is deeply curved towards the dorsal side, and acuminate. Gullet lies near the ventral side and extends beyond the middle of the cell. In the anterior third of the cell, there are one or two large oval bodies. Cells are but barely compressed. Measuring 27-38 x 11-16 p Cr. reflexa 16. à') Cells narrowly cuneiforM, elongated. Dorsal anterior end forms a short, cuspidate wedge or cone. Posterior end is sharply cuspidate. Cells are slightly sigmoid. Body is hardly compressed. Gullet extends to the middle of the cell. There are one or two ellipsoids in the anterior portion. Measurements: 15-19 x - 4.5-6 y Cr. gracilis 17. e) Cells narrowly cuneiform (not as thin as the fre-Evious species). Dorsal anterior end protrudes only a little, and is broadly rounded. Posterior end is tapered and more or less dorsally curved, cuspidate, but with the extremity usually slightly rounded.
