摘要:

New graptolite collections from Cape Providence, north of the section described by Benson and Keble in 1935, show a repetition, in reverse order, of the beds known to the south, on the gently-dipping northern limb of an assyrnmetrical east-west-trending anticline. Zones La 2β, La 3, Be 1, and Ch 2 were recognised. The Upper Lancefieldian Zone (La 3), not previously recognised, in New Zealand, in represented by poorly preserved graptolites, includingTetraqraptus approxinuitus, T. acclinans, T. decipiens,andSchisoqraptus waddickorumn.sp. (related to the Lower Bendigonian S. spectabilis of Victoria); no specimens ofT. fruticosuswere identified.
