REMARKS:
In the type population there is a large vartiation in the final chamber morphology. In some specimens, including the holotype (Fig. 3,Nos. 1, 2) the final chamber is about the same size as the penultimate,whereas in others, it is smaller, with a narrower aperture as in the figured paratype (Nos. 5, 6).
C. waiparaensis appears to be closely related to Zeauvigerina aegyptica Said and Kenawy which was illustrated and described by Beckmann (1957) from the Paleocene rocks of Trinidad; C. waiparaaensi's is different in that it lacks the necked aperture.
The specific name waiparaensis is derived from Waipara where the type sample was located in the MIddle Walpara RIver. C. waiparaensis was first used by Mr N. de B. Hornibrook as a manuscript name.

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
