eee wide and regular callus just surmounting keel where it joins

Holotype in collection of New zone Geological Survey. 
Height, 55 mm. ; diameter, 39-5 m 
Locality.—475, Mount Harris (= 8. Кеси of Pal. Bull. No. 8, р. 64). 
Remarks.—The lon ng sharp spines show that this shell is closely related 
to S. tuberculata, from which it differs in its greater size and higher spire.

Te Anau Lake; Kawau; Broken Hill (Uy Pe oba bly several species 
were represented ; the Broken River shell has become the type because 
it was represented as the example of the species in Hutton's type collection 
at the Dominion Museum. Thomson and Speight collected this fossil 
from the shell-bed immediately. above the limestone of Trelissick Basin

The type of S. cincta is from “ Awatere,” but the exact horizon was 
not stated by Hutton. Dr. Thomson’s collection from Lower Awatere 
(Pal. Bull. No. 8, p. 30) contains S. cincta, so this may be the type locality. 
The species has н recorded from many horizons — e.g., Kakanui; 
aihao „ченге. ; Target Gully; Pakaurangi; Duncan's, Tolaga Bay. 
These are based either on poor specimens or on a very wide interpretation 
of the species. The true 8. cincta has very coarse spirals of irregular 
appearance, and during the course of this revision has been seen only 
from 126, Awatére Valley, and 218, Motunau. 
The shell most often mistaken for it is S. subspinosa n. Sp., which has 
much the same outline, but p^ an consisting of numerous very fine 
regular spiral lirae, whereas in S. cincta the spirals are strong and Мера
