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, Martinitiue, 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 Amphiurae are so numer- 

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



Amphiura Verrilli? (young,) Ltm. 



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 Ltm. 



It seems to differ from the tjqje 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. 



Station 204, Martinique, 476 fathoms, 1 specimen. Station 288, Barbados, 

 399 fathoms, 1 specimen. 



Ophiocnida olivacea Ltm. 

 Station 344, 40° 1' N., 70° 58' W., 129 fathoms. 



Ophionema intricata Ltk. 



(Young.) Station 128, Santa Cruz, 180 fathoms. 



Ophionereis reticulata Ltk. 



Station 142, Flannegan Passage, 27 fathoms. Station 155, Montserrat, 88 

 fathoms. Station 276, Barbados, 94 fathoms. Station 278, Barbados, 69
