of their arrangement are hard to make out, and their appearance 

 varies with the position of the seta. Apparently there are several 

 rows so arranged as to give a double-bordered effect for the greater 

 part of the terminal portion of the seta. Just beyond the bend are 

 a number of very fine spines arranged in transverse rows. Dorsal to 

 these is a vertical row of very stout setae which extend beyond the 

 parapodium to a distance equal to about half the length of the latter. 

 These setae are light brown and the apex of each is prolonged into a 

 long spine with a diminishing series of smaller spines arising from 

 it (pi. 11, fig. 6). The whole terminal portion of each seta is covered 

 with minute spines. Appearing as early as the eighth somite there is 

 a tuft of three or four setae located dorsally to the large ones. Each 

 has a smooth basal portion, narrowed to a symmetrically pointed apex, 

 from either side of which a tuft of fibres is given off which form an 

 irregular fan-like arrangement (pi. 11, fig. 7). These setae are much 

 smaller than the heavy ones and extend only about half as far beyond 

 the parapodium.
