and not nearly so concave. The upper normal whorls in the 

 Chinese species are turreted and prettily coronated or tuberculated 

 at the angle, and the revolving sculpture of the spire is rather 

 stronger than in the present species, which does not exhibit any 

 coronation above. The tuberculation upon the transverse ridges of 

 the lower two-thirds of the body-whorl is also a good distinguishing 

 feature. 



Kiener's figure of C. recurvus (Coq. Viv. pi. 97. f. 4), if the out- 

 lines of the spire were the slightest less concave, would exactly 

 represent the form of this species.

Tryon^ could never have seen this species or he would not have 

 placed it as a variety of C. cervus, with which it has no relationship. 

 Weinkaufi^, in comparing it with C. tulipa and C. geographus, has 

 indicated its true affinity. 



The locality •' Swan River," which has been quoted for this 

 species, requires confirmation.

With this species 1 am inclined to unite the following as varieties: — 

 C. vicarius, Lamarck, G. verriculum, Reeve, C. tesctilina, Kiener, 

 C. iigrinus, Sowerby, C. corbula, Sowerby, C. scriptus, Sowerby, 

 C. panniculus, Lamarck, C. canonicus, Hwass, G. rubescens. Bonnet, 

 C. legatus, Lamarck, C. musivum, Broderip, C. pauluccice, Sowerby, 

 G. condensus, Sowerby, C. archiepiscopus, Hwass, C. abbas, Hwass. 



Great as is the difference in many respects between the extreme 

 forms, still I find it impossible to discover any permanent distinctions,
