somewhat variable ; and, especially, the first under arm-plate is not always 

 broken in two. Numerous specimens from the second "Blake" Expedition 

 show usually only three arm-spines ; three and often four irregular mouth- 

 papillse on each side, and disk-scales varying in thickness.

 Such diverse localities further prove the cosmopolite nature of this species. 



Amphiura Otteri? Ljn.

 specimen. 



I have not much question that this is Ljungman's A, Otteri which has some 

 variety as to size and curve of spines. The unique originals of this and many 

 other species were, with great kindness, lent me by Prof. Loven ; and Dr. G. 0. 

 Sars showed a similar generosity.

 Bay, Kerguelen IsL, 20 - 60 fathoms, 8 specimens. 



As I have combined AmpUpliolis wdth Amphiura, Prof. Studei-'s name has 

 become a duplicate to (Amphipholis) antarctica Ljn. I take, therefore, the 

 liberty of giving it the name of its discoverer, who kindly identified these 

 specimens by his own.
