As L.\MY rightly remarked there can be no doubt that C. calyculata Lam. (non Linn.), 

 and C. aspera Lam. are both synonyms of C. (A.) variegata Bruguière. 



The number of ribs on the shell is variable and not definitely twenty, as described by 

 Reeve. The "vaulted scales" are found only on adult shells, and may take on the form of 

 foliaceous spines or be altogether obsolète. The colour of the shells is usually some shade of 

 yellow with a large number of bluish or blackish spots often arranged in several rows trans- 

 versely to the ribs. 



Distribution : — C. (A.) variegata has a very wide range in the Indo-Pacific, and has 

 also been recorded from the Persian Gulf and the Red Sea. 



The "Siboga" Expédition coUected a fair séries of shells from the Anchorage off Pulu 

 Sarassa, Postillon Islands (St. 43), Madura Bay, Molo Strait (St. 51), Western entrance, Samau 

 Strait (St. 59), Macassar (St. 71), Anchorage off Kawio and Kamboling Islands, Karakelang 

 Group (St. 129), Saleyer Anchorage (St. 213) and Anchorage east of Dangar Besar, Saleh 

 Bay (St. 313).
