15a. Pentaceros gracilis (Liitken), young. 



Locality. — XIY., Bushby Island, 15 fathoms, rock and sand. 



Apparently a young specimen. i? = 65. 



Disc not very high. Five large apical tubercles and three small ones 

 around the anus. 



The lophial line of tubercles distinct : tubercles few and small on a 

 line on either side of the lophial line. 



Supero-marginals with a single distinct tubercle generally absent on the 

 most proximal but one ; placed higher on the most proximal plate. 



Infero-marginals with a similar tubercle, occasionally absent near the 

 distal end. 



Actinal surface with plates distinct, granulated, with a tendency to 

 tubercles on the innermost ones. 



Small valvular pedicellaria? on proximal plates of the row adjacent to the 

 ambulacral grove, one on each plate. 



Ambulacral armature : inside row of five or six spines, among which one 

 or two seem decidedly larger : then two, large, stout, blunt : and finally 

 an inconspicuous row of two or three small ones. 



The specimen bears some resemblance to P. chinensis, Gray, but is 

 probably a young form of P. gracilis.
