312 MELVILL AND STANDEN: SHELLS FROM LIFU. 
phery, the middle keel being strong, squarely built, and bold 
and projecting further from the whorl than the two other keels. 
Shell much depressed, apex papillary, sunk in the spire ; spiral 
crenellz run round the sutures and round the peristomial 
callosity, this being tongue shaped and well nigh concealing the 
umbilicus. One specimen only, discovered in the mouth of a 
larger shell by the Rev. Lewis Shackleford.

Smaller than 4. rubra Pease, and differing from all the 
forms we have seen of it, and likewise of the Japanese A. ocel/ata 
A. Ad. in the whorls being plainly five in number, and in the 
different pattern of the interrupted red lines, the shape being more 
effuse than A. ocel/ata, and the shell smaller than in A. 7udbra. 
There seem affinities with 4. /7xeata Pease from the Hawaiian 
Islands, of which we have only seen a description, but here the 
whorls are fewer, the lip is not thickened out, the apex is pink, 
not white. Though small, it is a very brightly coloured little 
sheli, being five whorled, the whorls slightly swollen, white, with 
transverse interrupted red lines encircling it spirally, round the 
periphery these lines are regularly interrupted, leaving equal 
white spaces, below the suture on the last whorl are square 
white spaces left bare, the mouth is round, lip slightly effuse, 
plain ; the columella having a very strong tooth near the base.
