Chlamydophorella grossa
Chlamydophorella grossa Manum and Cookson, 1964
Ioannides, 1986, questionably included this species in Chlamydophorella.
Holotype: Manum and Cookson, 1964, pl.5, fig.1
Locus typicus: Graham Island, Arctic Canada
Stratum typicum: Cenomanian
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Original description: [Manum and Cookson, 1964, p. 17-18]:
Description:
Outline of shell subcircular to circular. The wall is less than 0.5 µm thick and bears fairly widely spaced rod-like processes, 4-6 µm long and 0.7-1.5 µm broad, which expand at their ends and support a very thin outer membrane. In some specimens an opening in the wall, interpreted as an apical archeopyle, is present.
Dimensions:
Holotype: overall diameter 117 µm. Range in overall diameter 78-136 µm.
Affinities:
The specimens from Graham Island possess the characteristic shell-wall of the genus, but differ from the existing species in their considerably larger size and the thicker and more widely-spaced processes.
The specimens upon which Alberti (1961 p. 18) established his new genus Gardodinium appear to have all the characters of Chlamydophorella and therefore probably belong to that genus. However, they differ in size and shape from C. grossa.
