With regard to the numl)er of the cirrals this species is most 

 <;loseIy related to Si. diadema, but well separated from this by the 

 formation of Cd, by the shortness of the cirri, when compared with 

 the arms (the latter are at least twice as long as the cirri) and by the 

 darge and many prominences on the ossicles of the arm-bases. By 

 this the new species approaches Daidalometra (hana), a genus jiroperly 

 distinguished from Stenometra only by a smaller number of arms. The 

 above-desci'ibed species is to a certain extent a transition-form between 

 the above-mentioned genera.
