1 Scirparia or Scirpearia Cuv. is said to be distinguished by Polyps placed alternate 

 on the two sides. This genus is founded on Pennatula mirabilis, Polypus mirabilis 

 LINN. Mus. Adolpk. Frederici Regis, Holmiae, 1754. Fol. Tab. xix. fig. 4. p. 96. It 

 is very possible that LINNAEUS afterwards mistook a foreign species (from China, see 

 Amosnit. 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 LINNAEUS' description, 

 was not known at Stockholm, as my friend Prof. SUNDEVALL wrote to me (4 July, 

 1846).
