Cashia limacoides (Page, 1967)
Diagnosis: L 7.5-25.5 µm (median 14 µm), tapering from rather broad anterior end (L/B 3.3) to narrow posterior end, which may be smooth or bear small bulb; crescent-shaped hyaline cap much reduced or absent; nucleus 2.8-4.1 um; no crystals; no cysts; sucker-like surface structures 30 nm in diameter; mitochondria never elongate.
Ecology: Freshwater. North America, Europe. Multiplies slowly.
Remarks: With the finding in Cashia limacoides of distinctly helical mitochondrial cristae, that character is added to the diagnosis of the genus. The species included in the earlier key (Page, 1976) as Cashia angelica is now listed under Saccamoeba, q.v.
