Pentinastrutn peutacephaleu7i^ U. Sp. 



All five arms equal, club shaped, at their egg-shaped 

 distal end twice as broad as at their base, and armed with 

 a strong conical spine. Several smaller spines on the 

 border of the patagium which is complete, not quite fill- 



ing up the interbrachial spaces. Resembles very closely 

 Pentinastrum goniaster, Haeckel, from which it differs 

 mainly in not forming such a regular pentagium and 

 having spines on the patagium. 



Dimensions. — Radius of .each arm 0.19; basal breadth, 

 0.03; distal breadth, 0.006 ; radius of the central disk, 

 0.025.
