Species Leupoldina cabri Sigal 1952


Discussion / Comments:
Banner & Desai (1988):
It does not seem possible realistically to distinguish between the taxa which are listed above in synonymy for this group. There appear to be all intermediates between those adult specimens with four chambers in a whorl and those with five. Broad chamber extensions develop ontogenetically at the fifth or later chamber following the proloculus (compare the appearance of narrowly constricted tubulospines as early as the second chamber after the proloculus in Schackoina cenomana - see e.g. Masella, I960). The. elongations are in thickness about 1/3 of the chamber length (compare Schackoina, where the tubulospines are 1/4 to 1/5 as thick as the chamber is long). The last-formed or penultimate chambers may have double, bifurcating elongations ; in such specimens, the earlier part of the tests seem identical to other tests which carry single elongations on each chamber. We can see no reason to consider these forms to be different species, and they could not in practice be distinguished if the last-formed chamber were missing.
