" The American examples of this species, of which a large series was 

 taken at station 49, nve, all distinctly longer in the ray, and liave the 

 paxillfB of the abactinal area somewhat more délicat« and less compact in 

 character tlian in the European forms, although even in these some variation 

 occm'S. It Avould, however, be an easy matter to say wliich were the 

 American examples out of a large umnber of mixed specimens, and on these 

 giounds I consider that we are dealing with a well-marked variety.

" A small species, with a large disk and rapidly tapering arms, the 

 angles between which are distinctly rounded ; the rather naiTow amljulacra 

 are bounded by a row of long spines arranged by threes on each adambu- 

 lacral, outside of which are other rows so closely i^acked as to be almost 

 disorderly in their disix)sition ; the intermediate ]:»lates which fiU up the 

 rather large interbracliial area, but do not extend far into the rays, are 

 closely covered with sharp spiniform gi'annles. The marginals are shoi-t 

 but quite distinct, and the superomarginals, though much less wide than 

 the inferomarginals, remain distinct to the top of tlie arm. They are both 

 covered liy large granular x)lates, which sometimes take on the ap^Dearance 

 of spines; there are from 20 to 40 marginals on either side of each arm. 

 The dorsal sm-face formed of the ends of fine x)axilla% the form of which is 

 obscm-ed by the integument wliich invests them.
