3. Astropecten andromeda, Muller and Troschel. (. Astropecten 
christi , Diiben and Koren,* Of vers. K. Vet.-Akcid. Forhandl., 1844, 
p. 113). 
Station 7. Aug. 12, 1880. Lat. 59° 37' N., long. 7° 19' W. 
Depth, 530 fathoms. A single example. 
Muller and Troschelf described their species as sometimes furnished 
with small single spinelets on the supero-marginal plates ; but no 
trace whatever of such are to be found in the specimen under notice. 
In this respect I can confirm the observations of Sars,J and Danielssen 
and Koren,§ and also the description given by Diiben and Koren.|| 
In the “ Knight Errant ” specimen all the spinulous or papilliform 
appendages of the actinal surface are invested with a thick 
membranous tissue which is often more or less united at their bases, 
and in some parts coalescent even at their extremities, which are 
joined by web-like and fibrillar extensions. The appearance thus 
produced is accurately enough expressed by Diiben and Koren’s 
“ gelatinost ofverdrag,” H and I have no doubt whatever as to the 
correctness of their description in this respect ; although the character 
referred to has subsequently been called in question. Sars** states 
definitely that it did not occur in any of his specimens, and he con- 
sidered that Diiben and Koren had been deceived by the presence of 
foreign matter. Diiben and Koren state that the character is not a 
constant one. 
Remarks. — Astropecten andromeda has not previously been dredged 
out of the “ cold ” area. The present seems to be an instance of its 
occurrence within the limits of the “ warm ” area. Itf seems pro- 
bable from this and other sources of information that some modifica- 
tions will ultimately be required when drawing up a revision of the 
characteristic fauna-lists of the two areas. 
* The date of the first publication of Diiben and Koren’s name- was incor- 
rectly cited by Dujardin and Hupe {Hist. Nat. Zooph. Rchinodermes, p. 420) 
as 1834, — a mistake which has subsequently been copied, and has led to an 
erroneous priority being accorded to Diiben and Koren’s name. In 1846 
Diiben and Koren themselves acknowledged Muller and Troschel’s claim.
