East Coast of China; Schånau, November 15, 1895. 
One specimen; cirri XXXIII, 12—13, 12 mm. long; first joint 
short, second one-third to one-half longer than broad, third to 
fifth half again as long as broad or rather longer, somewhat ''dice- 
box shaped”, then becoming shorter, the eighth and ninth squarish, 
the remainder not so long as broad; seventh and following joints 
with slightly everted distal dorsal ends; opposing spine small and 
short, but prominent, scarcely reaching one-third the diameter of 
the penultimate joint; terminal claw longer than the penultimate 
joint, stout, comparatively slightly curved. 
About sixty arms 150 mm. long with three or four, rarely 
five, post-radial axillaries; brachials rather strongly overlapping, as 
in P. gracilis, and the pinnule joints finely spinous dorsally; the 
general build, also, is slender and delicate as in that species. 
Except for the greater number of the cirri, the specimen 
aågrees with numerous others at hand from the Philippine Islands, 
and I have no hesitation in referring it to this species on the 
strength of the data given in the "”Challenger” report. i

The genus Comanthus is equivalent to the "Valida” and "Par- 
vicirra” groups of "Actinometra” ås understood by Dr. Carpenter, 
omitting from the latter A. variabilis and A. multifida, which belong 
to Comaster. The species of the "Valida” group are all synonyms 
of the Comatula rotalaria of Lamarck except C. valida, which 
is closely related to that species. 
The. genus Comanthus includes about twenty species, falling 
into three definite groups. These groups are differentiated by cha-
