 sont très-petites et peu nombreuses.

The same species is described by Lütken ^vho refers it to ArcJiaster 

 [ '64, p. 136] : 



" I det nysnsevnte Vœrk beskiiv- 

 er og afbilder Möbius fremdeles en 

 Söstjerne under Navnet Stellaster 

 sulcatits (p. 2.,^^ t. IV f. 1-2) efter to 

 törrede Exemplarer, uden Lokalitets- 

 angivelse, i Hamborgs Museum ; jeg 

 gjenkjender denne Art i et Hgeledes 

 töiTet Exemplar, som lœnge har 

 henhgget i det tidligere kongelige 

 Museum, ligeledes unden LokaHtets- 

 angivelse, men har derved tillige 

 havt Leilighed til at overbevise mig 

 om, at det ikke er en Stellaster men 

 en ArclmsterP Der er ingen Liglied 

 mellem de smaae Paxiller, hvormed 

 hele Rygfladen er beklœdt, og de 

 store kornede Rygtavler hos en 

 Stellaster ; dens hele Bygning er 



1) Evidently a misprint of 11. 



2) " Paa det foreliggende Exemplar kan 

 Tustedevœrelsen af Anns ikke erkjendes, da 

 det har vœret gjeunemstnkket af en Xaal Hge 

 i Centrum, hvor Anus jo Hgger hos Archasterne, 

 og hvor den jo ogsjia efter Möbius's Beskrivelse 

 har ligget (hvorimod SteUasterne have en 

 subcentral Anus). Med Archaster hesperus 

 M. Tr. har jeg ikke havt LeiUghed til at 

 sammenligne den og kan derfor ikke udtale 

 mig om dens ForskjelUghed fra eller muhge 

 Overeensstemmelse med denne Art." 



Li the last mentioned work 

 MoBius also describes and figm-es a 

 starfish under the name Sfellaster 

 sulcatm (p. 2.,^^ t. IV, f. 1-2) after 

 two dried examples, without state- 

 ment of locahty, in tlie Hambm-g 

 Museum; I recognise this species in 

 a likewise dry example, wliich has 

 lain for a long time in the former 

 Koyal Museum, also without state- 

 ment of locality, but lias thus at the 

 same time given occasion to convince 

 me that it is not a Stellaster but an 

 ArcJiaster P There is no similarity 

 between the small paxillas, with 

 which the whole dorsal smiace is 

 clothed, and the large granulated 

 dorsal plates of a Stellaster ; its 



2) In the example lying before me the 

 presence of the anus can not be recognised, 

 as it had been pierced by a needle exactly in 

 the centre, where the anus certainly Uos 

 in the Archaster-species, and where it lies 

 also according to Mosras' description (on the 

 contrary the SteUaster-species have a snb- 

 central anus). I have not had occasion to 

 compare it with Archaster hesperus M. Tr. 

 and therefore can not pronounce on its differ- 

 ence from or possible coincidence with this 

 sijecies.
