Extra details from original publication
REMARKS: In the type sample there are 6 dextrally coiled and 4 sinistrally coiled specimens, and within its range it does not appear to show any coiling preference. Some specimens have small final chambers which tend to be out of the plane of coiling and nearer to the umbilicus than normal and with a smaller aperture as in the figured paratype (Nos. 116-118).
G. insolita is rare but quite distinctive in the samples from the Port Elizabeth section.
The specific name is derived from the Latin insolita meaning "uncommon""."

Editors' Notes
The article was published in the December 1965 issue of the journal but appeared in early 1966, so for taxonomy the correct date is 1966
