1 Scirparia or Scirpearia Cur. is said to be distinguished by Polyps placed alternate 
on the two sides. This genus is founded on Pennatula mirabilis, Polypus mirabilis 
Linn. Mus. Adolph. Frederict Regis, Holmie, 1754. Fol. Tab. xrx. fig. 4. p. 96. It 
is very possible that Linnaus afterwards mistook a foreign species (from China, see 
Amenit. Acad. Iv. p. 257) for one from the North Sea (Fauna Suecica, p. 543, ‘‘habi- 
tat in oceano Norvegico’’), and this last may be Virgularia mirabilis. To me the genus 
Scirparia appears very doubtful. The type which served for Linn us’ description, 
was not known at Stockholm, as my friend Prof, SuNDEVALL wrote to me (4 July, 
1846).
