"ogive" (no, not "olive" ;)) might be a suitable term, though our
ovus-without-spheres object would be a slightly more generalized shape
(even the most generic variant of a true ogive still has one pointed end).

I'd be really reluctant to make the parameterization of such an object
fit a special use case such as limbs; parameterization of primitives
should generally be linked to the underlying mathematical representation
in a straightforward manner, and any use-case-specific parameterization
should be done via macros; that's what they are for.

As another consequence, in the absence of an "open" keyword the ends of
such a shape should not be spherical, but planar.
