794 LIST OF MOLLUSCA FROM NORTH-WEST AUSTRALIA, 



This species is very common at Port Essington and Port 

 Darwin. During the Chevert Expedition I obtained it at 

 Darnley Island, Torres Straits, in 30 fathoms. This is the species 

 described by Reeve as Nassa rutilans, with the locality of New 

 Zealand on the authority of the late Mr. Cuming, who was gifted 

 with the art of inventing localities, and who never visited New 

 Zealand, and who was also in the habit of destroying the 

 habitats sent with specimens, as he said they could be discovered 

 by looking at the work in which they were described.

Nassa bicallosa, E. A. Smith. Journal Linn. Soc, Vol, XII., 

 p. 543, pi. 30, fig. 1, 1876 ; Tryon, Manual of Conchology, Vol. 

 IV, p. 36, pi. 11, fig. 142, 1882. 



This species appears to have a wide range. The type specimen 

 came from Nicol Bay, Western Australia (Brazier) ; Swan River, 

 Western Australia and Cape Natal (British Museum.) 



5. Voluta (Amobia) pk.etexta. Reeve.

 Vol. III., p. 269. 



6. Oliva Caldania. Duclos.

I believe that Oliva australis, Duclos, figured in his Monograph at 

 pi. 8, figs. 3 and 4 is identical with this species. It is found at King 

 Ceorge's Sound ; Adelaide, South Australia ; and Victoria. 0. Cal- 

 dania we obtained it at Mud Bay, Cape York, North Australia, 5 

 and 11 fathoms; also Torres Straits, in the Chevert Expedition; New 

 Cuinea and Solomon Islands. The Polynesian Islanders use the 

 smaller species extensively for the manufacture of ornaments.
