Dear Annelida members,
Here is an extract from a posting on iczn list by Neal Evenhuis. It concerns
Diptera and the BMNH. I do not know if the same ever applied to BMNH
Polychaeta. But it is a general warning that 'type' or 'syntype' put on a
label by some museum's curator (perhaps even by the curator's junior
assistant) should not be accepted uncritically. Evenhuis is talking about
'lectotype by accident' where authors merely repeat label information that may
not be what it seems.
=========== quote begin
The fact that the BMNH specimens had a red-ringed "Type" label on it stemmed
from WWII when the curators arbitrarily selected one specimen for each row of
syntypes as the "Type" and marked it with the red-ringed "Type" label. These
types were taken away from the museum for safety from bombing to a location in
the country. The remainder of the collection was also taken away from the
museum for safety, but to a different location.
After the war, the specimens were reunited at the BMNH but the "Type" labels
were not immediately removed. [They have been now for the Diptera (in the last
few years, though) and replaced with proper "Syntype" labels; but I have heard
that in other sections of the BMNH this still has not been done, lending
itself to further accidental lectotype fixations.]
When Hardy arrived in the early 1950s, what he saw at the BMNH were those
arbitrarily selected "Type" specimens and not Holotypes or Lectotypes. His
dutiful mention of the label data and use of the words "Type in BMNH" has
caused those species to have been accidentally selected as lectotypes."
