times notably larger than the respective ventral cirrus, and a single 

 embedded aciculum (pi. 59, fig. 8). Neuropodia are provided vi^ith a 

 ventral cirrus and simple setae that are sometimes accompanied with 

 furcate setae (pi. 62, fig. 7) or also pointed setae. The cutting edge of 

 the unforked setae is beset with a single row of pointed teeth (pi. 59, 

 fig. 6). 



Pilargis has heretofore been known by 3 species, but one of these, 

 P. tardigrada (Webster) remains only briefly known. Another species 

 is herein described as new. These species are : 



1. P. verrucosa St. Joseph (see Fauvel, 1923, p. 251) from southern 

 Europe 



2. P. berkeleyi Monro 



3. P. tardigrada (Webster) (1879, p. 268) dredged off Virginia 



4. P. maculata, new species
