Introduction
Davie (2002: 397) commented that 'there has been much speculation about the identity of this taxon. Preserved material lent to Ellen Clark by the Natural History Museum and said to belong to the type series appears to have been the south-western Australian species, C. preisii (Erichson, 1846) rather than C. bicarinatus. Subsequently, she treated the two as synonyms. The dry specimen nominated by Riek (1969) as 'lectoholotype' appears to match the specimen figured by Gray in his original description (based on examination of the types in the BMNH by J.W. Short). Riek's assertion that C. bicarinatus is a valid species allied to C. quadricarinatus and C. rhynchotus rather than C. preisii appears correct (J.W. Short pers. comm.)'
