STARFISHES OF THE PHILIPPINE SEAS. 349 



A specimen from station 5141 has numerous much larger pedicel- 

 lariae with slender, curved, spatulate jaws about 4 times as high 

 as the granules. These are on the papular areas while the usual slit- 

 like form occupies the trabeculae. 



The adambulacral armature does not agree with the description 

 of Perrier. There as 7 or 8 furrow spines (5 or 6 in the type), but 

 in at specimen from station 5254, 9 or 10. Subambulacral spines 2 

 or 3, heavy, with wrinkled tips. External to these is a second series 

 of 2 or 3 shorter spines, or rather enlarged granules, likewise with 

 slightly wrinkled tips. Perrier speaks of but 1 series of subambu- 

 lacral spines. These specimens are really triplacanthid according to 

 Bell's classification. The granules of the actinal surface are very 

 unequal in size, some of them being fairly tuberculate. 



A young example with R=:23 mm. has developed low primary ra- 

 dial spines, several superomarginal spines, and upward of 5 supero- 

 marginal spines at the end of ray only. The disk is low and the 

 general appearance goniasterid. A slightly larger specimen has 

 developed a few additional lophial spines. Furrow spines 5 or 6; 

 usually 2 subambulacral spines. 



Four to 6 small intermarginal plates are present in each inter- 

 brachium. The largest can sometimes be detected, but the smallest 

 are obscured by the granules.

Remarks. — This species seems to have been known previously only 

 from New Caledonia, where it has a near relative, O. novae-cale- 

 doniae (Koehler). It is nearest O. linckii, to which none of the
