Whether the sunken appearance of the ra- dial sliields and the correspondingly re- markable division of the disk into fifteen wedge-shaped parts is characteristic of the species or only an accentuated individ- ual peculiarity can not, of course, be de- termined w i t h o u t more material. But it is hard to doubt that the main fea- tures of the peculiar disk will be found to be characteristic of the species. OPHIOMITRA POLYA- CANTHA, new ; Disk 6 mm. in di- ameter; arms al)oiit 30 mm. long. Disk circular, covered with numerous small, rather regular scales,many of which bear each a low, thorny stump. Radial shields small, triangular or s({uarish, about as wide as long, distinctly separated. Upper arm plates small, rhombic or triangular, with convex distal margin, widely separated from each other; between the upper arm plates the arm is somewhat constricted.
