Dear Phil and Trivia-pursuers,

Cate (1979; 105-106; fig 105 [holotype])) described Pusula (P.) padreserrai
and compared it to Pusula solandri (G. B. Sowerby II, 1832).  He wrote that
the former differed from the Sowerby species "by having a much larger,
lightweight shell, by being more widely, roundly ovate, rather than
narrowly so .... by having a subspherical, highly elevated shell in which
dorsal rib-ending tubercles are very much more fine, less obtrusive."  He
goes on and writes the confusing passage [my edit]: "The shell color is
completely different, a mixture of pale fawnish-pink and beige; the colors
of P. (P.) solandri being a characteristic mauve color, with [back to P.
padreserrai now] the color deepening in a longitudinal line at the base of
the very large dorsal rib-ending tubercles, whereas in the Sowerby species
ribs are bright, off white."  Finally: "The shell ribbing in this new
species is considerably finer and more delicately sculptured."

Apparently Turgeon, Quinn, et al. (1999) agreed with Cate and dropped P.
solandri in favor of P. padreserrai between the first (1988) and second
editions of the checklist. Although in a distinct minority, I use the
citation "Turgeon, Quinn, et al." rather than "Turgeon et al."  Note that
Jim Quinn's name is the only one that is not in alphabetical order after
that of the senior author.  Although I haven't asked Dr. Turgeon what this
means, in the medical literature at least, it is customary to consider an
author thus placed as senior to the others whose names follow, and I think
that's what Turgeon had in mind.
