 ond, subspatulate, bluntly pointed, sometimes faint lat- 

 eral notch; pectinae deeply lacinate, slightly shorter to 

 slightly longer than lobes, arranged 2, 2, 3, 3, those of

 from caudal margin; genacerores 0-1(3-8)3-5; dorsal ora- 

 ceratubae in two rows on each side; each lateris with 

 three small serrated projections. Cuba on Cocos,
