Astroclon Suensoni n. sp. 
Å new East Åsiatic Euryalid. 
Preliminary Notice 
by 
Dr. Th. Mortensen. 
In a collection of zoological objects made this year by Captain 
E. Suenson 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 closer examination the specimen was found to belong to the 
genus Åstroclon, which was established by Lyman for a single 
specimen collected near the Kei Islands by the ,,Challenger" Ex- 
pedition (Station 192. Lat. 5? 42'S., Long. 132? 25' E. 129 fathoms; 
26: TX. 1874). " The …»Challenger" species, named by Lyman 
Åstroclon 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 
åugmented through the fact that this specimen proved to be the 
representative of another, quite distinct 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.
