230 RECENT OPHIURANS. 



Mr. Lyman left with this specimen a sketch of the mouthparts and the 

 notes "8-10 spines"; "Amphim-a sp. nov.? A." It is a remarkably well- 

 characterized species, owing to the large number of arm-spines and the conspicu- 

 ous tentacle-scales.

489. A. POECILA, sp. nov. (midXa^, many colored, pied). Plate 5, f. 12, 13. 



Disk 4 mm. in diameter; arms 16-20 mm. long. Disk covered with a coat 

 of very numerous minute scales among which the six primary plates are con- 

 spicuous. Radial shields less than a millimeter long, and much less than half 

 a millimeter wide, slightly divergent, separated their entire length. Upper arm- 

 plates much wider than long; distal margin slightly, proximal margin very 

 much, curved; more or less broadly in contact throughout. Interbrachial spaces 

 below covered with a very fine scaling. Oral plates oval, a trifle longer than 

 broad, widest distal to middle. Adoral plates rather large, meeting not only 

 proximal to oral shield but in midradial line also. Oral papillae typical; sub- 

 dental, moderately large, squarish, near together; distal, large, thick, spine- 

 like and erect. First under arm-plate concealed by meeting of adoral plates 

 in midradial line; succeeding plates squarish with rounded angles, shghtly wider 

 distally than proximally, about as long as wide, broadly in contact. Side arm- 

 plates small, not meeting either above or below; bearing series of 5 or 6 (rarely 7) 

 subequal, flattened, blunt spines, rather longer than an arm-joint. Tentacle- 

 scales 2, the one on the side arm-plate larger; the one on the under arm-plate
