Taxacom: probable noun in apposition

[David Campbell]

Gardner (1948) named *Macromphalina pierrot*, using that spelling six times
in the paper (USGS Professional Paper 199B;
https://nam10.safelinks.protection.outlook.com/?url=https%3A%2F%2Fpubs.er.usgs.gov%2Fpublication%2Fpp199B&data=05%7C01%7Ctaxacom%40lists.ku.edu%7C98432050704941bb07a108daa19e2a00%7C3c176536afe643f5b96636feabbe3c1a%7C0%7C0%7C637999997927589389%7CUnknown%7CTWFpbGZsb3d8eyJWIjoiMC4wLjAwMDAiLCJQIjoiV2luMzIiLCJBTiI6Ik1haWwiLCJXVCI6Mn0%3D%7C3000%7C%7C%7C&sdata=6SSEOb4f54uFH0Ki6f1fI5bpbnVd5KdEjQqOcNcy9zw%3D&reserved=0 is legible but not the best
scan, last I checked).  An etymology is not given, but she stated
“*Macromphalina
pierrot* is well characterized in the perfect adult by the jaunty tilt of
the protoconch”.  I suspect this means that "pierrot" refers to the stock
tragicomic character or a corresponding costume, with his beret to one
side, treated as a noun of its own in apposition rather than as a proper
name to be Latinized to *pierroti.  *Although this choice seems possibly
confusing , as Recommendation 31A points out, it appears to me to be a
legal usage, and later uses of *pierroti *would be incorrect emendations.

Any thoughts?
