276-282. 
Lampert (2/) has produced a complete revision of the Holothuroidea, 
and gives keys for all the genera and species. He divides the Denclro- 
chirotce , with Bell, into Decachirotce and Polychirotce ; in the former he 
emends Cucumaria , and forms a new genus, Semperia , for those in which 
the tentacles are sporadipod ; the latter he divides into the Monocyclia 
and the Amphicyclia ; the Elasipoda are included.
