[Taxacom] Taxonomic question

 I would disagree very slightly with both Doug and Francisco in that I would say that it is the *intention* to denote a taxon which is the proper criterion, or else many old descriptions would be rendered unavailable for many important taxa! However, with a fossil, one might have to distinguish a taxonomic description from a mere description of which parts of the organism are preserved?

 1865 p. 468 should be this one:

in addition to Doug's cited characters:

"the coriaceous integument of the body, and the hairs attached to the feet"
and
"resemblance to the recent genus Lycosa"

I would not employ the term "sad", for it lacks a neutral approach to 
the situation. Either this description denoted the taxon at the time 
when this was published, or not. Arachnological expertise is necessary 
to judge this. If it did not denote the taxon, i.e. if the description 
did clearly not allow to distinguish the taxon from others known at the 
time, then the next available source must be consulted.
