in the Senonian beds of Seymour Island, Graham's Land, together with 
K. bhavani and Trigonia arctica, which also occur in the St. Vincent 
beds, where is Puzozia gaudana, also found in the Senonian beds of Peru, 
Pondicherry, and South Africa, with other widespread Senonian genera 
not specifically identified ; nor does Piroutet (1917) discuss the affinities 
of the fauna, which, however, seems to be clearly representative of the 
general Indo-Pacific Upper Senonian fauna. 
This fauna is also represented in New Zealand, spreading over the 
greater part of the North Auckland Peninsula, the eastern portion of the 
North Island, the northern and rather to the south of the central portion 
of the east coast of the South Island. The presence of Gryphaea and

Dieseldorff (1901), may indicate an Upper Cretaceous transgression of 
the sea over the ancient land-mass of that region, but the information 
available does not permit us to decide whether the region remained 
continuously submerged until Middle Tertiary times, or whether some 
emergence of the land occurred in the interval, the late Cretaceous or 
early Tertiary times. The investigations of Woods (1917) on the fauna 
of the north-east of the South Island of New Zealand has shown that 
absence of any noteworthy community with the Australian Cretaceous 
fauna. Trechmann identifies some shells with the “ Natica ” variabilis 
new species.
