Astrochalcis micropus n. sp. 
A new Euryalid from tlie Philippines. 
Preliminary Notice 
by 
o 
Dr. Tli. 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 wkich at 
once appeared to me to represent quite a new type. On a doser 
study I found it to be really a hitlierto unknown species, appar- 
ently nearest related to Astrochalcis 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 
recently published new form Astroclon 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.
