that they form the upper part of the Maitai Series. The Annehcl 

 Beds have not been traced in the Nelson district, the classical area 

 of the Maitai Series ; but he had himself found a piece of annelid- 

 like tube in the Maitai Limestone of the Wairoa Grorge, accom- 

 panied by Za])}irentis and Pernio- Carboniferous brachiopods. 



He did not think the Mount-Torlesse Annelid Beds in any 

 way equivalent to the Yakutat Slates of Alaska, as he had shown 

 that the large bivalve in the Maitai Argillites overlying the Lime- 

 stone near Nelson, formerl}^ supposed to be Inoceramus, is ap- 

 parently identical with Aplianaia L. Gr. de Koninck, of the 

 Permo-Carboniferous of New South Wales. 



Inoceramya TJlrich, of the Yakutat Slates, is a shell of the 

 Inoceramus group, and bears a row of areal ligament-pits. The 

 Lias, or at least the Lower Jurassic, is a well-defined formation 

 in New Zealand, where it overlies the Trias, and in no way 

 resembles the Annelid Beds. 



He felt much interest in the fact that Dr. Bather had determined 

 the scanty crinoid remains that he collected in the Kaihiku Beds 

 as rather of Upper than of Middle Triassic age. All evidence that 

 these deposits were Permian or Lower Trias seemed now entirely, 

 removed.
