COMPLETE HARTMAN: POLYCHAETES FROM CALIFORNIA 51 



base of the parapodium and near the sides of the lower lip. The next 

 ventral cirri are inserted like the others, at the midlength of the 

 neuropodium. 



Elytra probably number 15 pairs, as characteristic of the genus. All 

 specimens are broken near the middle and most elytra have fallen away. 

 Those that remain cover the dorsum completely and are approximately 

 circular in shape; they are thin, translucent, and have entire margins; 

 they lack tubercles. 



Parapodia are lateral ; the notopodium is reduced in size and emergent 

 from the upper side of the neuropodium. Its setal fascicle is directed 

 laterally in fairly compact bundles. Neuropodia are much longer, di- 

 rected laterally ; the lobe terminates in a long, slender triangular acicular 

 lobe. 



Notopodial setae are of a single kind ; all are long and slender, distally 

 whiplike and delicately serrated along the cutting edge. Neuropodial setae 

 are of 2 kinds. The supra-acicular setae are similar to the notopodial 

 setae in thickness and length and are similarly serrated along the cutting 

 edge. The subacicular setae are slightly thicker, distally delicately bifid, 

 and coarsely serrated along the cutting edge ; they range from longest in 

 the upper part of the series, to much shorter at the lower end. 



Harmotho'e priops is easily distinguished from other species of the 

 genus in its small size (less than 10 mm long) and its characteristic 

 barred pigment pattern. The anterior prostomial eyes are forward, under 

 the prostomial peaks, and the posterior third of the prostomium is 

 speckled with tiny black eyespots. Notopodial setae are unusually fine, 

 hairlike, directed laterally, and upper neuropodial setae are similar to 

 them. 



It was frequently taken in shelf depths of southern California. Speci- 

 mens are usually associated with Harmotho'e lunulata (delle Chiaje) 

 and many other small polychaetes.

Collections. Many individuals were taken in grab samples from Point 

 Conception to south of the Mexican border; others are from Tomales 

 Bay, California. They come mainly from shelf and slope depths below 

 intertidal levels, down to 300 m, rarely to 1000 m, in sediments of fine
