Hab. AniwaBay; 17 fathoms : Tatiyama : Kino-0-Siraa. 

 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 narrowei*, 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
