42. VoLUTA (Scapha) magnifica. 



Valuta magnifica, Chemn. Conch. Cab. xl. p. 8 ; Reeve, Conch. 

 Icon. Vohita, pi. 1. f. 2. 



This noble Volute, almost the largest of the genus, seems to attain 

 its maximum growth in Port Jackson. It is now a shell of rare oc- 

 currence, and is found half burying itself amongst weed and ooze 

 on sandy and muddy flats beyond tide-mark. Rose Bay, Vaucluse 

 Bay, and Middle Harbour are its favourite localities. It occurs in 

 places along the coast, such as WooUongong, Botany Bay, and Bris- 

 bane Water — and extends northwards to iMoreton Bay, where the 

 specimens found are tuberculated. Length 12 inches. 



A3. *VoLUTA (Amoria) angasi. 



Voluta a7igasi, Sowerby, Tlies. Conch. Voluta, f. 99. sp. 7'3. 



This species (which was formerly confounded with V. iindulata. 

 Lam.), although plentiful in Tasmania, is rare in Poit Jackson. It 

 ranges northwards as far as Richmond River, where its yilace is sup- 

 plied by V. zebra. Leach. The true V. nnJulata of Lamarck is 

 from Port Lincoln and the Great Australian Bight. Specimens have 

 been found at INIiddle Harbour and at Cabbage-tree Cove, outside 

 Manly Beach. Length 3 inches. The Tasmanian ones are rather 

 larger, and of a deeper colour. 



44. AULICA marmorata. 



Vohita marmorata, Swainson, Exotic Conch, i. pi. 4. 

 A rare and elegant shell, of rather light inflated structure, with 

 the whorls sharply tubercled at the upper part and attenuated 

 towards the base. It is of a pale fulvous orange-colour, sparingly 

 painted with waved chestnut lines, descending from the sutures, witli 

 two bands formed by a blue clouded shading of the markings. Port 

 tephen and Newcastle, New South Wales. Length 4^ inches.
