 den hvid (f arvelös). 



" Som anden Art af sin Slœgt Dori- 

 ijona (der vel allerliöjst vil kunne 

 gjöre Ki'av paa at vsere et kunstigt 

 Afsnit indeufor Goniaster) opförer 

 Geay (I.e.) D. longimana c : Ästrogo- 

 nium longimanum MÖBius (Neue See- 

 sterne, t. I, f. 5-6), og det er vel 

 niuligt, at denne Art, der udmserker 

 sig ved, at Rygrandpladerne beröre 

 liinanden i hele de lange Armes 

 Lsengde, saa at de egenlige Kyg- 

 plader aldeles ikke komme til Udvikl- 

 ing paa Armene, lier vilde faae en 

 ret naturlig Plads. — Der er i övrigt, 

 som jeg tidligere liar udtalt,^^ og som 

 ogsaa senere er erkjendt af v. Mar- 

 tens,-^ identisk med A. Souleyeti DuJ. 

 Hupe (Malakka-Strsedet), livilken sid- 

 stnœvnté Form af Gray med Uret

 — Jeg liar ligeledes tidlige paavist,*^ 

 at MöBius's Stellaster sulcatus (I.e., t.

3) " Af Pekrtebs Arbejde over Söstjernernes 

 Pedicellarier seer man, at Valexciennes havde 

 opfattet den som en ArcTuister. Der er vir- 

 kelig en Del Liglied f. Ex. mellem Goniaster 

 Mvlleri og Archaster hesperus, og eu slig Feil-

to be common in insect collections 

 from China and Japan ; the two ex- 

 amples lying before me are from an 

 exactly similar som'ce, and that of the 

 Berlin Museum was from Japan. 

 Like G. equestris it is white (coloiu-- 

 less). 



As the second species of his genus 

 Dorigona (which can perhaps at most 

 claim a place as an artificial division 

 inside Goniaster) Gray mentions (I.e.) 

 D. longi7ïicma=Astrogonium longima- 

 num MÖBIUS (Neue Seesterne, t. I, f. 

 5-6), and it is quite possible that this 

 species, which is distinguished by the 

 fact that the dorsal marginals touch 

 each other through the whole length 

 of the long arms, so that the dorsal 

 plates ]3i'opei' are not developed ou 

 the arms at all, would find its most 

 natm'al place here. — It is besides, as 

 I have previously expressed, ^^ and 

 as also later recognised by v. Mar- 

 tens,-^ identical with A. Souleyeti Du.J. 

 HuPÉ (Malacca Strait), which last 

 mentioned form is erroneously regard- 

 ed by Gray as a variety of G. eques- 

 tris P — I have also previously xDointed 

 out*^ that MÖBDJs' Stellaster sulcatus 

 (I.e., t. IV, f. 1-2) is an Archaster;

2) "I.e. (1866) S. 86." 



3) From Pekrier's work on the Pedieel- 

 Lxriœ of the starfishes it is seen that YAiyEXci- 

 ENXES had regarded it as an Archaster. There 

 is in fact some resemLlance e.g. between Goni- 

 aster Mïdleri and Archaster hesperus, and such 

 an error eould find a natural explanation and 

 excuse, if G. longimanus is a '■'Stellaster" or 

 a nearly aUied form.
