ANTEDOM LA RVI ('I a I! A. i80 



br. Fourth pinnule (on 8tli br.) of only 7 ov 8 small 

 joints , a good deal shorter than the third , and only 

 about one quarter as long as the second pinnule. Follow- 

 ing pinnules gradually increase in length and size, and 

 the joints of the later oues become more elongated ; but 

 they never reach the length of the large basal pinnules , 

 nor are they very closely set. 



Disc, naked and deeply incised, almost to the centre; 

 diameter 10 mm. 



Spread, 18 centira. 



Colour, calyx and arm-bases white with darker patch- 

 es; lower arms a dirty brownish grey, and their outer 

 portions the same mottled with white. Sacculi not very 

 close on pinnule ambulacra. 



Locality , Amboyna. 



9. Antedon Inericirfa , n. sp. 



Description of ati individual. 



Centrodorsal discoidal with a flat cirrhus-free dorsal sur- 

 face, and bearing about 30 cirrhi in a single or partially 

 double marginal row. Cirrhi of 25 — 30 tolerably uniform 

 smooth joints, few or none of which are longer than broad; pen- 

 ultimate has a faint opposing spine to the small terminal claw. 



First radials not visible ; the second short and nearly 

 united laterally ; axillaries more than twice their length , 

 pentagonal with wide distal angles. 



Nearly 40 arms of about 160 smooth joints. Rays div- 

 ide three times; each division of two joints, the first clos- 

 ely united to their fellows, and the axillary not a syzygy. 

 First brachials almost rhomboidal , relatively long and nar- 

 row , closely united to their fellows. Second joints much 

 shorter and nearly oblong; third (syzygy) nearly square. 

 The next six joints short and nearly oblong; the following 

 ones longer and sharply wedgeshaped with traces of a 

 forward projection alternately on opposite sides, as in the 

 last species. Outer joints becoming blunter, squarer and 

 slightly elongated towards arm-ends.
