STAEFISHES OF THE PHILIPPINE SEAS. 319 



the concavity being on the outer side. Soon these spines become 

 blunt and cylindrical, though often a little flattened at the tip, and 

 the series continues to the end of the ray, the spines becoming slen- 

 derer on the outer part of the ray, although not decreasing in length 

 until near the tip. The outer spine decreases in length, and bej^ond 

 the thirteenth is very short, disappearing entirely at about the middle 

 of ray. Along the proximal and distal margins of the plates are 3 

 or 4 more or less pointed granules, and on the outer margin 1 or 2 

 granules. 



Mouth i^lates rather narrow with 8 or 9 furrow or marginal spines, 

 very short on the outer end of series and increasing rapidly in 

 length toward the inner end, the 2 series of the combined plates be- 

 ing webbed at the base and forming an angular group or comb clos- 

 ing the actinostome. On all the plates but one there is a single 

 upright, long, compressed, subambulacral spine, chisel-shaped at the 

 tip. One plate has 2 such spines. Thej^ are similar to the subam- 

 bulacral, but slightly heavier. The outer and sutural margins are 

 surrounded by a single series of irregular subcorneal and convex, 

 sometimes compressed, granules. 



Madreporic body convex, situated halfway between center and 

 margin of abactinal area, surrounded by 5 plates only the 3 larger of 

 which actually touch the madreporite. Ridges irregular, branching, 

 without definite direction. 



Type.— Cut. No. 30557, U.S.N.M. 



Type-locality. — Station 5280, between Lubang and Luzon, south of 

 Manila Bay, 193 fathoms, gray sand; bottom temperature 49.6° F. ; 1 

 specimen. 



DistHbution. — Known onl}'^ from the type-locality. 



Remarks. — This species agrees with G. pedicellaris Fisher of the 

 Hawaiian Islands, and differs from C. cMldrcni Gray of Japan, and 

 C. haccatus Sladen from Cape of Good Hope in having numerous 

 broadly spatulate pedicellariae. Gorynetes is probably most nearly 

 related to pedicellaris., from which it differs in having very promi- 

 nent spines in the center of disk (the scars of C. pedicellaris would 

 indicate rather small tubercles) ; in having numerous abactinal and 

 a few marginal pedicellariae, in addition to the actinal intermediate 

 pedicellariae; heavy actinal intermediate spines; 5 to 7 instead of 

 8 or 9 furrow spines, the laterals being very short instead of sub- 

 equal to the mesial; pedicellariae which are very narrow at the base, 

 the jaAYS being broad, orbicular, concave, and entire. 



Callia-Hter mamilUfer Alcock^ differs in having the superomar- 

 ginals (G in number) in partial contact across the distal third of the 

 rays. These plates " have the form of great globules, each surmounted 

 centrally with a nipplelike spinelet," while the inferornarginal plates
