and Skogsberg 1920,p.153 have both forcefully 
pointed out that Ostrapoda, rather than Ostracoda, 
is the proper name for the Order. It was used by 
Desmarest 1925, p.380, and was actually adopted 
by Latreille himself in 1831 Cours dtEntomologie, 
peh29. Baird 1850, went back to Ostracoda, and 
with the exception of Stebbing, later workers have 
followed suit. It is unjust to Strauss, but it 
would be difficult to change with so large a body 
of literature existing in which Ostracoda is used.
