STARFISHES OF THE PHILIPPINE SEAS. 209 



ter of disk to base of ray, as in B. huddlestonii, the spinelets of ray- 

 being "well spaced and about 1 mm. long. A few plates have 1 or 2 

 minute spinelets in addition to the above. Numerous pedicellariae, 

 with 3 to 5 minutely thorny spinelets in each comb and with 2, 3, or 4 

 combs to each pedicellaria, are scattered over disk and form an inter- 

 rupted series along either side of ray near the marginal plates, for 

 about half the length of ray. The pedicellariae are very variable in 

 number on the ray. In the cotype there are 15 or 16 in each series ; in 

 the type about 3 to 5: in small specimens (R=up to 50 mm.) the 

 pedicellariae do not extend beyond the papular area. 



Papulae are distributed over disk and along ray as far as the be- 

 ginning of the third superomarginal plate. The end of the area is 

 bilobed. 



Superomarginal plates, subelliptical, longer than high, confined to 

 side wall of vay and with a long slender spine on the middle of the 

 upper margin, below which is a much shorter and slenderer rather 

 inconspicuous spinule and a second just aborad. The principal spine 

 is longest in the fourth, fifth, and sixth plates, there equaling the 

 length of 1.75 superomarginals (6 to 7 mm.). The surface of the 

 plate is bare, except for 1 to 3 minute spinelets, near the adoral mar- 

 gin of the plate. Interradial plate a little over 1.5 times as high as 

 the adjacent first superomarginal, bearing at its upper end a stout, 

 long, sharp spine (7 to 10 mm. long, or longer than r) and 3 acces- 

 sory spinules about 3 mm. long. Terminal plate broader than long, 

 Avith a broad notch adorad, and the surface covered with numerous 

 prominent spinules. 



Inferomarginals slightly in advance (aborad) of the superomargi- 

 nals, and with 2 subequul spines, a little smaller proximally than the 

 corresponding superomarginal spines ; distally the upper spine is con- 

 siderably longer than the superomarginal spine, while the lower is 

 conspicuously shorter than its companion. Pedicellariae occur be- 

 tween the inferomarginal plates irregularly in the interbrachium, 

 and also on the outer half or two-thirds of rays. The occurrence is 

 very variable even on different rays of the same example. Small 

 specimens may lack the distal pedicellariae, and the interbrachial are 

 lacking in a specimen, nearly as large as the type, from station 5619. 



The type has 6 actinal intermediate plates forming a single series. 

 The plates have a subcentral slender spme and 2 or 3 minute spinelets, 

 but no pedicellariae. In the cotype there is a pedicellaria in 2 inter- 

 radii. Three specimens from station 5619 have the pedicellariae and 4 

 lack them. One is interesting in having the pedicellariae between the 

 odd inferomarginal and the intermediate plates.
