Literature available only as a Chemical Abstract after September 1st 1978 is not, however, included. Naturally occurring halogenated monoterpenoids have been placed in a new section this year. Since many of them are now known to be cyclic compounds, it is no longer logical to classify them in the acyclic section. Non-naturally occurring halogenated monoterpenoids, however, continue to be reported in their respective sections.
