Nebela carinata
Nebela barbata, 115 µm – Ecuador

 

Nebela barbata Leidy, 1874

Diagnosis: Shell colorless, pyriform with an elongated neck, composed of a mixture of oval, circular and elongate shell plates, with numerous short, fine spines projecting from the junctions of the shell plates. Spines often flattened against the shell and difficult to see; aperture oval and surrounded by a collar of organic cement, the inner margin of which has about eight tooth-like protrusions.

Dimensions: Length of shell 96-106 µm; breadth of shell 38-44 µm; depth of shell 36-41µm; diameter of aperture 10-16 µm.

Ecology: Sphagnum vegetation

Remarks: Cash (1909) noted that the spines were seldom seen on specimens from Britain. Hoogenraad and De Groot (1940) also noticed this phenomenon. The same was true for specimens from Ecuador which I could observe.
