tion distinguishable throngli the superficial granulations. The rest 

 are of the steamsii-typG, being different from the typical gorgonia- 

 type in the disk scales being fine, flat and almost indistinguishable 

 through the superficial granulations. The specimen from Eno-ura, 

 however, rather resembles the venusta-tj'pe in the shape of the oral 

 shields and accessory oral shields. The largest specimen is 26 mm. 

 in the disk diameter and 95 mm. in the arm length. The number 

 of the arm spines increases with the growth of the animal.
