Hah. Kergiielen's Island. 



This species cannot be confounded with any which have 

 hitherto been described ; the number of the rays, the spade- 

 like form of the oral shields, and the peculiarities of the 

 ray-shields and spines at once distinguish it. The portion 

 of the disk which is visible on the lower side between the 

 arms is large, and the oral shields are only as long as the 

 space between them and the sides of the disk.
