Astrochalcis micropus n. sp. 
Å new Euryalid from the Philippines. 
Preliminary Notice 
by 
Dr. Th. Mortensen. 
After having described only two months ago a new species of 
the genus Astroclon, A. Suensoni Mrtsn., found in a collection re- 
ceived from Captain E. Suenson, I was very agreably surprised, 
on receiving a new collection from Captain Suenson (from San 
Bernardino Strait, Philippines), to find therein a Euryalid which at 
once appeared to me to represent quite a new type. On a closer 
study I found it to be really a hitherto unknown species, appar- 
ently nearest related to AÅstrochalcis tuberculosus Koehler among 
the Euryalids made known as yet. Whether it really belongs to 
this genus may certainly be somewhat disputable. I shall not, how- 
ever, at present establish a new genus for it, leaving the discussion 
of this question for the full report on this species and the other 
Tecently published new form Astrocl/on Suensoni. 
Diameter of disk 60 mm, width of arms near the disk 25 
—28 mm, height at the same point ca. 10 mm. 
The mouth-angles carry rather close set spiniform papillæ 
which increase in size towards the apex, where a bunch of about 
a dozen coarser teeth are found, arranged in 2—3 irregular, vertical 
rows, The mouth-angles are somewhat raised in the middle, appear- 
ing as five warts round the mouth.
