OpHIOZONOIDA, gen. nov. {dcpM^oiua + eUo^) . 

 Type-species: Ophiozonoida picta, sp. nov. 



Similar to Ophiozona but differing in three particulars: — (1) oral papillae 

 3 or 4 on each side, the proximal pair infradental in position, thick and squarish, 

 somewhat as in Amphipholis; (2) arm-spines short and stout, extending outwards 

 form the more or less flaring side arm-plates; (3) tentacle-scale single, large, 

 nearly circular, attached to the side arm-plate. 



The character of the arm-spines and the arrangement and form of the oral 

 papillae seem to warrant keeping this novelty out of Ophiozona. The disk, 

 however, is elevated, and is covered with large plates intermingled with small 

 scales much as in that genus, so there is even more reason for not referring the 

 present species to Ophiozonella. The disk-plates are not notably thickened 

 on their distal margins but are smooth and of nearly uniform thickness. 



1361. 0. PICTA, sp. nov. (picliim, copied in colors). Plate 18, f. 3, 4. 



Disk 3.5 mm. in diameter; arms about 10 mm. long. Disk covered with 

 large plates, intermingled with small scales; in the holotype it is difficult to 

 make out a definite arrangement but in the other specimens there is a large 

 central plate, 5 radial plates nearly as large, 5 pairs of somewhat smaller inter- 

 radial plates (1 proximal, 1 distal and marginal) and a still smaller radial plate 

 separating the proximal ends of each pair of radial shields; some 50 or more 

 scales surround, more or less imperfectly, or are mingled with these plates.
