It is well figured in Griffiths' Edition of Cuvier's Animal 

 Kingdom, but no description is given, and its name does not 

 appear in the letterpress. Reeve says it was named in honour 

 of Lord Milton, afterwards Earl Fitzwilliam. Its habitat 

 was unknown, and is first recorded in Thes. Conch, as from 

 Swan River, Australia. Later Mr. Angas cited it from 

 Fowler Bay, on the South Australian coast, and Mr. Bednall 

 gave me a specimen labelled Streaky Bay, a little distance 

 further east. Three specimens were taken by the Federal 

 trawler "Endeavour," all dead, one in 95 fathoms 90 miles 

 west of Eucla, measuring 11 cm. by 6'2 cm., with four distinct 

 vcolumellar plaits; a second in 88 to 100 fathoms in the same 

 locality, of 17'3 cm. by 9'7 cm., also with four distinct plaits; 

 and a third 19'2 cm. long, with only three plaits, correspond- 

 ing with the anterior three of the other specimens. It has 

 a much more prominent protoconch and a more elate spire 

 than the second, but otherwise they are quite similar. 



Two individuals, from Fowler Bay, obtained from Mr. 

 W. Reed, were taken alive. They have the typical narrow 

 elliptic form, somewhat elate spire, the incurved spines, and 

 four columellar plaits, with abundant white triangles in the 

 ornament. Their walls are of medium thickness. One has in 

 the body-whorl six well-marked axial costations, corresponding 

 with similar axial gutters within, and running down from the 

 spines, showing that the animal curved its shell outwards as 

 it proceeded to form the scale of the spine, and curved it in 

 as it completed the spine.
