 Hab. — Coast generally, in rocky parts. 



Obs. — After a careful study of some hundreds of specimens 

 before us, we arrive at the conclusion that there is only one 

 species, showing very great variation, both in form and 

 colouration. 



C. angustata, the type, is the dominant form throughout, and 

 usually attains to the greatest size of any of the series, and we 

 would define the principal distinguishing character of this form 

 in contradistinction to its varieties, as being of a uniform colour 

 on the dorsum, in fresh specimens generally purplish or reddish- 

 brown, and showing no bands. We would class the varieties in 

 the order of the date of naming, as follows : — 



Var. piperita. Type described as having four bands on the 

 dorsum, being dotted or speckled, and other colouration of dorsum 

 very light brown. 



Var, comptoni. Type described as having three bands on the 

 dorsum. No spots on the dorsum are mentioned. Other colour- 

 ation as in C. angustata, but much paler in tint, occasionally 

 being cream colour. 



Var. bicolor. Type described as of a light cream colour, and 

 having three broad irregularly interrupted bands crossing the 

 dorsum. No spots on the dorsum mentioned. 



Var. declivis. Type described as liaving the dorsum of a rosy 

 yellow hue sprinkled over with small spots. No bands are 

 mentioned. 



Var. albata. Type described as having a snow white shell, not 

 showing any spots.
