Hab. Aniwa Bay; 17 fathoms: Tatiyama: Kino-O-Sima. 
This is a large and handsome species, with the upper thread- 
like ridges of the whorls beaded, and the lower ones simple. It 
is of a reddish flesh-colour, blotched and variegated with pale 
chestnut at the sutures and periphery. 
The animal has a large prominent muzzle, bearded at the end. 
Head-lobes none. Tentacles prismatic, flat above, beset with 
short cilia, and lineated with red-brown. Eyes on dull black 
bulbs with small bright black pupils at the end of subtruncate 
white swellings, supported on thick cylindrical white pedicels. 
Neck-lappets large, the left white, plain-edged, notched near 
the eye-pedicel, and involute ; the right also white, but festooned 
and with the margin shortly ciliated. Lateral filaments with 
short cilia, four on each side, each with a red-brown line down 
the middle. Mantle-margin finely papillose, and shortly reflexed 
over the front edge of the shell. Foot milky white, speckled 
and reticulate with red-brown (the same colour as the markings 
on the shell), very long, powerful, and thick, acuminate behind, 
truncate in front, with two little slender tentacular filaments at 
the angles, prismatic behind the operculum, where it is flat 
above, with two prominent ridges at the angles; margin of sole 
shortly ciliated. 
The animal often greatly extends the foot, and uses it as a 
lever to turn over and regain its original position. 
Serpulus Adamsi, Morch. 
The animal is pale pearl-white, minutely flecked with opake 
white. The tentacles are flattened, short, and somewhat tri- 
angular, bearing a minute sessile black eye at their outer bases, 
just within the commencement of the neck-lobe. The under 
edge of the tentacles and the neck-lobe are adorned with regular 
rather distant yellow dots, forming the pupils of as many oliva- 
ceous eye-like spots. The head is green, sprinkled with white, 
and with a vertical groove extending down the middle. The 
head is very long, gradually growing narrower, and ending be- 
hind in a tapering point, and in front in a short and rounded 
muzzle. 
The foot is large, fleshy, hollow at the sides, and spotted near 
the fore part with olive-green, At the lower edge there is a
