under arm-plate, and in having five (not six) arm-spines, of which the lower 

 are larger, and have a rudimentary cross-piece at the tip. 

 Station 211, Martinique, 357 fathoms, 1 specimen. 



Amphiura sp. nov. ? 



Plate V. Figs. 64-66. 



Similar to preceding (Station 211), but with much smaller tentacle-scales; 

 sharp mouth-papilla?. " 



Station 220, St Lucia, 116' fathoms, 1 specimen. 



These last three species may be new ; but as the Amphiurse are so numer- 

 ous and run so close, I prefer to await a larger series of specimens. 



Amphiura Verrilli ? (young,) Lth. 



Differs from the type in having smaller radial shields and the primary disk- 

 plates not conspicuous. 



Station 226, St. Vincent, 424 fathoms, 1 specimen. 



Amphiura tomentosa? (young,) Ltm. 



Differs from the original in having the radial shields touching and side arm- 

 plates meeting above. These may be characters of the young. 

 Station 230, St. Vincent, 464 fathoms, 1 specimen. 



Amphiura angularis Lym. 



It seems to differ from the type only in having radial shields a little closer 

 and the disk-scaling less marked. Both A. angularis and A. tomentosa are 

 from the Kerguelen Islands.

 399 fathoms, 1 specimen.
