Nomenclature of the Moss-mites 
63 
cerned is thin ice. Each of these attempts at reidentifica- 
tion will have to be reconsidered without prejudice. 
Oudemans .has thus brought together for future study 29 
pre-Hermannian species, each so poorly described as to re- 
quire expert knowledge of most species at the locality from 
which they came or as to require their being considered 
nomina nuda. The list, chronologically arranged, follows. 
Acarus coleoptratus Linne 1758; Sweden. 
“ g'eniculatus same; TJtrech, Holland. 
“ fungorum same; Sweden. 
“ scaber same; Sweden. 
“ tremellce Linne 1761; Sweden. 
“ mus corum Scopoli 1763; Carniola (Krain, Austria), 
i lichenum same; same. 
“ piger same; same. 
“ spinipes 0. F. Muller 1776; Denmark. 
“ lichenum same; possibly an Oxibatid; not Scopoli. 
“ seminulum same; Denmark. 
“ corticalis DeGeer 1778; TJtrech, Holland. 
“ marginatus same; same; not Sulzer 1776, a tick. 
“ plantarum Mayer 1781; Germany. 
confervee iSclirank 1781; Austria. 
“ coleoptratus Schrank 1781; same; not Linne. 
“ geniculatus same; same; not Linne. 
“ musci same; Austria. 
“ lucidus Fourcroy 1785; France. 
“ scaber Rathke 1799; Bergen, Norway; not Linne. 
Trombidium corticate Rathke 1799; Bergen, Norway. 
“ coleoptratum same; same. 
“ loricatum same; same. 
Acarus coleoptratus Shaw 1800; England; not Linne. 
“ infusionum Schrank 1803; Bayern. 
“ planicornis, xylariw ciliatus, alatus all same. 
The six synonyms might be allowed to die of neglect ; their 
reidentification would not affect subsequent nomenclature. 
Should a 90 per cent vote to disregard the remaining 
twenty-three species, cast by present day Acarologists who 
have studied the Oribatoidea, be considered sufficient opinion 
to rule these authors out of systematic literature ? Or 
should they be retained as about 23 unavoidable nomencla- 
tural changes for the future?
