in this volume of the Peters Checklist, the publication
date is printed in parentheses.
The interpretation that this taxon was not published until 1852 is a presumption
that requires support and documentation.
Rand offers no explanation for this date, and it is not supported by
Sclater Syst.Aethiop. 2:635; CBBM 8:164; or the Richmond Index.
Indeed Rand himself cites (p.329) Dryoscopus sublacteus
Cassin from the page following this (p.246) to 1851 (!!!).
H&M 3rd:458 has the date correct as 1851.
Thanks to Colin Jones for picking up my error in following the Peters Checklist
on this erroneous date.
