Collection. — 465-35. One specimen. 



Length of about 200 segments is 90 mm; nearly complete, a small 

 posterior portion missing. Body dark purplish brown. The dorsum is 

 almost solidly covered with sand particles, the ventrum is pilose, covered 

 with filiform papillae that are longest at the sides around the parapodial 

 bases. 



The prostomium is pale, more or less translucent, to be seen only 

 by lifting away the first elytra and the peristomial ring. Its dorsal 

 margin, at the base of the stout ceratophore, is fused to the peristomial 

 ring (pi. 22, fig. 268), and its lateral and ventral parts are somewhat 

 telescoped in the first segment. No eye spots can be distinguished on 

 any part of the prostomium or ceratophore. 



The elytra are triangular (pi. 22, fig. 270) to subquadrate (pi. 22, 

 fig. 269), heavily fimbriated at their exposed parts, and with a single, 

 elongate lobe on the inner ectal margin. The dorsal surface is papillated. 



The notopodial fascicle is full, thick, much as in P. spinosa, the 

 numerous fine, hair-like setae project laterally far beyond the neuro- 

 podial setae. The neuropodium is distally truncate, slightly oblique. The 

 superior and median neuropodial setae are much heavier than the in- 

 ferior setae. Their shafts have several transverse rows of weak serra- 

 tions or are quite smooth, the appendages are falcate, distally entire 

 (pi. 22, fig. 272) or bifid. Inferiormost setae have a much longer ap- 

 pendage. Setae of the second segment include some with a spinose shaft, 

 and a long appendage with (pi. 22, fig. 271) or without bifid tip. 



In its parapodial and elytral structures, this specimen agrees with 

 the accounts of P. antipoda (Schmarda). It differs, however, in that its 

 prostomium is without eyes.
