* Axelson, in 1906, assumed the name Linnaoiemi, but, to avoid con- 

 fusion between liis earlier and more recent publications, he suggests that 

 both names should appear in reference to his works published since 1900. 



t The ppecilic name eUnu/aia having been used by MacGillivray (1896), 

 Axelson reiuxmed the species produda in 1906.
