DISCOVERY REPORTS 



The feet (Fig. 8, b) are biramous, but the dorsal branch is reduced. On the top of 

 the foot a sheathed aciculum makes a small projection, and with it is a bundle of about 

 a dozen long, fine, toothed, capillary bristles.

The ventral branch consists of two large bluntly conical lips from between which the 

 bristles come out. The uppermost ventral bristles are similar to the dorsal but rather 

 stouter; a little lower there are three or four much stouter and shorter toothed bristles,
