NO. 1944. NEW GENERA AND SPECIES OF STARFISHES— FISUER. 609 



conical spinules; the first and 3 or 4 last plates without spinules; 

 inferomarginals proximally as wide as length of 3, slightly arched, 

 but actinal surface not at all strongly beveled; outer end armed with 

 oblique comb of 4 slender, sometimes slightly curved, closely placed, 

 appressed spines, the lowest or next to lowest the longest and about 

 1| to If plates in length; spaced from these are proximally 2 spaced, 

 flattened, sharp spines nearly as long as longest lateral spine; general 

 surface covered with squamiform spinelets often spatulate in form; 

 adambulacral plates with 4 (proximally 5 or 6 and distally some- 

 times 3) rather long, flattened spines, the laterals subtruncate or 

 round-tipped; subambulacral spinelets proximally 12 to 16, subequal, 

 slender, often flattened and only about half as long as median furrow 

 spine ; most of the plates with a conspicuous fasciculate pedicellaria, 

 made up of 6 or 8 of the subambulacral spines; on each ray 7 or 8 

 actinal intermediate plates in a single row, armed with slender 

 papilliform spinelets and sometimes a central lanceolate appressed 

 spine; an occasional proximal plate with a fasciculate spiniform 

 pedicellaria. 



Type.— Cat. No. 30515, U.S.N.M. 



Type-locality. — Station 5520, 4.5 miles southwest of Point Tagolo 

 Light, north coast of Mindanao, 102 fathoms; bottom temperature, 

 61.3° F. 



CTENOPHORASTER DIPLOCTENIUS, new species. 



Very closely resembling C. hawaiiensis in general appearance, but 

 differing in having no median radial area of smaller irregularly 

 arranged paxillae; in having the paxillse in regular curved transverse 

 series on rays, with fewer paxillas to the series than in hawaiiensis; in 

 having finer superomarginal spinelets and more numerous, minute, 

 superomarginal fasciculate pedicellaria; in having slenderer and fewer 

 inferomarginal spines, arranged in 2 oblique arcuate lateral series, 

 and 1 transverse actinal series (not 3 and 2, respectively, as in liawaiir- 

 ensis); in having tiny inferomarginal and numerous prominent actinal 

 intermediate and subambulacral fasciculate pedicellaria; in having 

 fewer subambulacral spines, and prominent central spines to the 

 actinal mterradial plates. K = 105 mm., r= 15 mm., R = 7r; breadth 

 of ray at base, 18 or 19 mm. 



Type.— C&t. No. 30516, U.S.N.M.

 (lat. 14° N.; long. 120° 22' 30'' E.), 118 fathoms, mud, shells, coral 

 sand; 1 specimen; bottom temperature, 57.4° F, 



PSILASTER GOTOI, new species. 



R = 58 mm., r = 14 mm., 11 = 4.1 r; breadth of ray at middle of 

 interbrachium, 16 mm.; at third superomarginal, 13.5 mm. Disk 

 fairly large, rays evenly tapered to a pointed extremity; interbrachia 

 48702°— Proc.N.M.vol.43~12 39
