Bathycrinus Carpenteri. 



Syn. Ilycrinus Carpenteri, Danielssen & Koren. 



I nyt Magazin for Naturvidenskaberne x leverede jeg 

 sammen med min afdøde Yen, Dr. J. Koren, en forelobig 

 Beskrivelse over en Solilie, som vi kaldte Ilycrinus Carpen- 

 teri. Vi antog, at den maatte være saa forskjellig fra den 

 af Wyville Thomson beskrevne Bathycrinus gracilis 2 , at 

 den ikke kunde henføres til denne Slægt. Imidlertid viste 

 det sig senere, at Thomsons Exemplar var et ungt. lidet 

 udviklet og beskadiget Dyr, og som Folge deraf var Be- 

 skrivelsen høist mangelfuld. Bathycrinus gracilis blev fun- 

 det i den biscaiske Bugt af Porcupine-Expeditionen 1869 

 og beskrevet i 1872. Senere blev ved Challenger-Expedi- 

 tionen opdaget to Arter, henhørende til denne Slægt, nemlig 

 Bathycrinus aldrichiani og Bath. campbelliani. 3 Af den 

 første udkastede Wyville Thomson en Beskrivelse i „Journal 

 of the Linnean Society, 1876", hvorved han yderligere be- 

 grundede Slægten Bathycrinus. Omtrent samtidigt indleve- 

 rede vi til Magazin for Naturvidenskaberne vor foreløbige 

 Meddelelse om Ilycrinus Carpenteri, udeii at være vidende om 

 W. Thomsons sidste, noget mere udførlige Beskrivelse af 

 Bathycrinus aldrichiani, men da jeg ved at korrespondere 

 med Hr. Dr. P. Herbert Carpenter og ved at sende ham 

 en Del af et Hoved til Sammenligning, samt endelig ved 

 Gjennemgaaelsen af hans ypperlige Værk over Crinoiderne, 

 er jeg bleven fuldt overbevist om, at Ilycrinus falder sam- 

 men med Skeeten Bathycrinus og maa derfor inddrages.

Syn. Ilycrinus Carpenteri, Danielssen & Koren. 



In ,.Nyt Magazin for Naturvidenskaberne" 1 I, together 

 with my deceased friend Dr. J. Koren, delivered a precur- 

 sory description of a sea-lily which we called Ilycrinus 

 Carpenteri. We supposed it to be so different from the 

 Bathycrinus gracilis described by Wyville Thomson - that 

 it could not be assigned to that genus. It appeared, 

 however, subsequently, that Thomson's specimen was a 

 young, little developed, injured animal, and in consequence 

 thereof the description was very defective. Bathycrinus 

 gracilis was found by the Porcupine expedition in the Bay 

 of Biscay, in 1869, and was described in 1872. On the 

 Cliallenger expedition, subsequently, there were discovered 

 two species pertaining to that genus, viz. Bathycrinus al- 

 drichiani and Bath. campbelliani. 3 Of the first-named, Wy- 

 ville Thomson gave a description in „Journal of the Lin- 

 nean Society. 1876". in which he still further substantiated 

 the genus Bathycrinus. About the same time we forwarded 

 to „Nyt Magazin for Naturvidenskaberne" our precursorv 

 report on Ilycrinus Carpenteri without being aware of W. 

 Tliomson's last, somewhat more detailed description of 

 Bathycrinus aldrichiani; I have since, by correspondence 

 with Dr. P. Herbert Carpenter and sending him a 

 portion of a head for comparison, and, finally, from the 

 study of his able work on the Crinoids, become fully con- 

 vinced that Ilycrinus coincides with the genus Bathycrinus 

 and must therefore be included in it.
