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 Hucla, measuring 11 cm. by 6°2 cm., with four distinct 
columellar plaits; a second in 88 to 100 fathoms in the same 
locality, of 173 em. by 9°77 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.
