The second specimen, Professor Speight tells me, was found at the - 
Kaiwara Creek in a calcareous gritty greensand which here forms the base 
. of the series of Cretaceous and Tertiary rocks; these, as usual, rest with j 
a high unconformity on middle or older Mesozoic rocks. This specimen, о 
though somewhat crushed, can be identified with certainty as a species е 
of Nautilus. @ 
Nautilus sp. aff. suciensis Whiteaves. (Plate 65, fig. 1.) 
The specimen is 120 mm. in diameter and 80 mm. 
face is broadly rounded, and umbilicus appears to be 
wards, but at shoulder bend in a gentle curve strongly backwards and pass 
rd loop. The 
over periphery with backward loop 
in British Columbia, in rocks of Senonian age. No species of this group 
of Nautilus has previously been recorded from New Zealand.
