Preliminary Notice 
by 
I)r. T/£. Mortensen • 
In a collection of zoological objects made this year by Captain 
E. Snenson in the Japanese Seas on repairing telegraph cables 
there was, among several other interesting Echinoderms, a large 
specimen of a Euryalid which at once attracted my attention. On 
a doser examination the specimen was found to belong to the 
genus Astroclon, which was established by Ly man for a single 
specimen collected near the Kei Islands by the „Challenger u Ex- 
pedition (Station 192. Lat. 5° 42'S., Long. 132° 25'E. 129fathoms; 
26. IX. 1874). The „Challenger u species, named by Ly man 
Astroclon propugnatoris, being still known only from the single 
specimen dredged by that Expedition, it was very interesting here 
to find another specimen, and the interest was even considerably 
augmented through the faet that this specimen proved to be the 
representative of another, quite distinet species. I shall give here 
a preliminary description of this new species, naming it, in honour 
of the collector 
Astroclon Suensoni n. sp. 
Diameter of disk 55 mm; width of arm near the disk 14—15 
mm, height at the same point 12—13 mm.
