S. etre teet This also appears to be a mistake, for in his Manual (1880, 
p. 219) Hutton used S. australis Gmel. as the equivalent of his S. scutulata 
Desh., and listed S. tricarinata as a different species.

As the locality of the holotype is unknown, it is a pity that this shell 
was described. In appearance it resembles young S. vermis, particularly 
those forms which have the tubercles well developed. the specimen 
represents the normal adult it is a valid species, closely related to Ж. tri- 
carinata and S. vermis.

spiral striae of somewhat irregular stre e prominence of the spiral 
cinguli, and the presence on them of tubercles, are the most variable 
features. The arrangement of these cinguli corresponds to that of S. canali- 
culata, and, indeed, to that of the whole group.
