Introduction.

During the investigation of the rich graptolitic Ordovician fauna of Preservation Inlet, New Zealand, by Prof. W. N. Benson and Mr R. A. Keble, numerous examples of fossils referable to the Phyllocarida came to light. These were kindly placed in my hands by Professor Benson, for determination and description, and the following are the results of a study of the forms present in the collection.

All types have been placed in the collections of the Geology Department, Otago University.
