JAPANESE ASTEEOIDEA. 351 



septum, about one-tliircT r from margin. Stomach capacious, tlie thick hepa- 

 tic cœca reaching into ray about one-half R. 



" Variations. — The chief variations concern the length of the abactinal 

 spines and the height of the peclicellariaß. A specimen from station 4292, 

 vicinity of Kadiak Island, and three from station 3080, coast of Wasliington, 

 have considerably shorter abactinal spines than all the others, but they 

 difler still from typical phrygiana in having prominent marginal spines, 

 longer adambulacral spines, and higher pedicellariBe. The actinal pedicellarise 

 are the most variable, in some cases tending toward the form characteristic 

 of californica. The jaws have either smooth or serrate edges. 



"In Calif ornian specimens the spines are all very prominent, more so 

 than in the northern examples, and the actinal pediceUarise are j)lainly 

 serrate. The Monterey Bay (station 4552) example has more numerous 

 marginal spines than the example from off southern California (station 3664). 

 In both, the rays are notably stouter and shorter than in typical phrygiana. 

 Tlie specimen from station 4552 has the following characters: R = 71 mm.; 

 r=40 mm. ; Il==1.75r. Breadth of ray at base, 48 mm. Height of longest 

 abactinal spines, 6 mm. Disk very rigid, marginal plates massive, the 

 iipper with proximally two or three spines as long as those of abactinal 

 X3lates, distally with one or two ; more of the inferomarginals have three 

 spines, occasionally fom*. Marginal spines of both series stand in . line, 

 forming a perpendicular series of six in iutsrradial arc (sometimes seven), 

 then five, fom*, tlu-ee, and finally two. Pedicellarise numerous, the jaws 

 slightly Avider than liigh ; actinal a trifle higher than abactinal ; none on 

 marginal plates. Actinal intermediate plates with short subconical spines 

 forming a gi'oup of four or five (in addition to the granules), or they may 

 smTOimd the pedicellaria when that is present. They are equal to or 

 only slightly higher than j)echcellari?e. All granules skin-covered, depressed 

 or conical, but not denticulate or rugose as in H. ccdifornica. Colour in life, 

 a bright scarlet vermilion. 



" Type-locality. — Departiu-e Bay, British Columl^ia, 18 fathoms. 



" Distribution. — From southern California to Alaska (Kadiak Island) in 

 27 "to 121 fathoms.
