Mr. W. L. May, of Tasmania, writes May, 1897:—‘“I 
have had an opportunity of examining the type specimens 
of Mangelia cancellata, Beddome. There are a number of 
specimens in the box, and they are very variable, ranging 
from your D. felescopialis to D. pentagonalis. There are 
several intermediate forms. I should consider that M/. can- 
cellata came about halfway between your species, and that 
they all belong to one very variable species, 1. cancellata.” 
Dredged in 20 fathoms Investigator Strait, 1; in 35 
fathoms off St. Francis Island, 1 dead, brown colour; in 55 
fathoms off Cape Borda, several good; in 90 fathoms off Cape 
Jaffa, 1 perfect ; in 110 fathoms off Beachport, 1 perfect, 1 
broken ; in 130 fathoms off Cape Jaffa, 2 perfect.

Dredged alive in 13 fathoms Spencer Gulf; 17 fathoms 
and 20 fathoms Backstairs Passage; and dead from 8 fathoms 
upwards ; in 40 fathoms off Beachport, 3 quite fresh. Taken 
on the beach St. Francis Island, 2 good. 
The foot is about half as long as the shell, truncated in 
front, pointed behind; white; the sole dotted abundantly 
with small orange-brown spots, larger and darker along the 
margins; upper-surface with brown spots as large as pins’ 
heads, with a deep-purple-brown central dot, also at the 
junction with the body; muzzle dark-spotted ; siphon light- 
brown, with small spots. Tentacles and eyes exactly like 
Glyphostoma paucimaculata, Angas. No trace of an oper- 
culum to be found; hence I have removed it from Drillia to 
Clathurella.
