* A typical specimen of this species received from Dr. Liitken, while agreeing in 

 most characters with those described in the preceding article (page 274), differs in hav- 

 ing much smaller and shorter spines both above and below, the inner row on the upper 

 marginal plates not reaching beyond the seventh or eighth plate, and in having the ter- 

 minal papillae of the paxillae considerably finer, while the paxillse are also smaller and 

 shorter. This specimen being somewhat smaller (greater radii 215 inches), these differ- 

 ences may be due to age.
