AwoNGST the fossil shells from Dowling Bay (see р. 106 of this volume) 
was a small trochoid form which could not be placed in any New Zealand 
species so far described. Its appearance was, however, reminiscent of 
a shell found at Ardgowan, near Oamaru, and on ooking u up references 
i was found that this shell also was undescribed. It was evidently a 
Calliostoma, but no species of this genus is mentioned in Suter's Ardgowan 
list, the only trochoid shells given being two new species of Basilissa, so 
that either this shell had not been collected or it had been placed in 
. Basilissa and not yet described. Several fragments of the same species 
were found at Target Gully, also one or two fragments of another 
Calliostoma. In Suters Target Gully list the only shells that might be 
connected with these species are Trochus tiaratus Q. & G., “әр чот 
n. sp., Basilissa n. sp. Now, although Trochus Adis. Q. & G.. has a

material of Marshall’s collecting, Зарина in the Otago University School 
of Mines, nor amongst the Target Gully specimens in the Geological 
Survey collection. It is first mentioned in this connection by Marshall

it are recorded T. tiaratus Q. & G. and Trochus n. sp. : = still fuller

record is T. tiaratus Q. & G. and T. chathamensis (Hutt.). The latter can 
be easily identified, and ded does occur there. Park (1918, pp. 88,
