NO. 3 HARTMAN : POLYCHAETOUS ANNELIDS 225 



area VII has 3 to 5 rows of larger paragnaths, more or less continuous 

 with area VIII but diminishing to only a single row at the sides. 



The prostomium is dark brown or rust colored, and a similar pigment 

 forms broken bands across the segments dorsally. Parapodia have diverg- 

 ing middle and dorsal lobes (pi. 35, figs. 53, 56), and a postneuroacicular 

 lobe which is somewhat flaring, but shorter than the acicular lobe itself. 

 Notopodial (pi. 35, fig. 55) and neuropodial (pi. 35, fig. 54) falcigerous 

 setae have appendages about equally long. The former have a few serra- 

 tions or are quite smooth. The neuropodial falcigerous appendages are 

 delicately spinose along the cutting edge. 



Distribution. — California. Intertidal, to 14 fms. Marine and estu- 

 arine.

Collection. — 901-38. One individual. 



Length of 94 segments (not quite complete) is 50 mm. The prosto- 

 mial lobe is longer than wide ; the palpi extend distally slightly beyond the 

 prostomial antennae. The posterior parapodial lobes are dark over their 

 free portions; these lobes are flat, compressed (pi. 33, fig. 36). 



Paragnaths are weakly developed, area I without cones; area II with 

 about 8 to 10 cones in 2 sparse rows; area III with about 6 in a trans- 

 verse row ; area IV with 7 or 8 cones in 2 rows ; area V with none ; area 

 VI with 3 or 4 cones in a transverse row; areas VII and VIII with about 

 8 larger cones in a row on the maxillary side and 1 or 2 irregular rows of 

 smaller cones on the oral side. Homogomph falcigerous notopodial setae 

 are first present from about the twenty-seventh segment. 



Distribution. — Northeast Pacific, south to southern California. Inter- 

 tidal.

Length to 30 mm ; number of segments about 65 ; pale except for 

 dark eyes and acicula. The proboscidial formula is approximately as fol-
