69. DOSTNIA SCULPTA. 



Artemis sculpta, Hanley ; Reeve, Conch. Icon. Artemis, f. 52. 



This species may readily be distinguished by its concentric strise 

 being decussated at the sides by fine radiating lines. Dredged in 

 Port Jackson. Length 1 inch. At Moreton Bay it attains a larger 

 size. Some of the Port Jacksou specimens are shghtly tinged with 

 rose-colour at the umbones.

I have only met with young examples of this fine species in Port 

 Jackson. Japan, Ceylon, and North Australia are cited as its habi- 

 tats. Full-grown shells measure nearly 2 inches across.

 Dredged at Mossman's Bay and off Spectacle Island. This species 

 was first obtained by the late F. Strange at Moreton Bay ; hence its 

 name by Deshayes.

 or less radiately mottled Avith grey, and shining. Dredged in mud, 

 at the mouth of Lane Cove and Parramatta River. Length 2| inches.
