more distally, into the base of the cirrophore. The neuroacicular lobe is 

 shown rather long, extending from the neuropodial lobe. Here it is 

 largely concealed by the presetal and postsetal lobes (pi. 59, fig. 8). 

 Also, in the original account the neurosetae are shown with an accessory 

 tooth that is proportionately larger than may be the case. Ventral cirri of 

 the first few segments were not identified but since they are small they 

 were perhaps overlooked. 



P. Berkeley i resembles P. tardtgrada (Webster) in having long, dor- 

 sal cirrophores but in the latter the dorsal cirri are said to be leaflike and 

 ventral cirri of the first segment are shown notably smaller than their 

 respective dorsal cirri. Furthermore, P. tard'igrada was described as 

 "everywhere white" whereas P. berkeleyi has the conspicuously colored 

 dorsal cirrophores. 



I am indebted to Dr. Edith Berkeley for an individual from the type 

 locality. 



Distribution. — Puget Sound, Washington; Tomales and San Fran- 

 cisco Bays, also Elkhorn Slough (MacGinitie, 1935), California; inter- 

 tidal to 16 fms.

This is a very long, broad, ribbonlike species. A larger individual 

 lacking head and anterior segments measures 140 mm long for 325 seg- 

 ments. A smaller one with head but without tail is less than half as 

 large, but agrees with the first in other respects and comes from the same 

 locality. The body tapers anteriorly to a small, inconspicuous prostomial 

 lobe. It is broad through long median and posterior regions but tapers 

 rapidly to the posterior, constricted pygidial ring. Epithelial papillae 

 are scattered over most of the prostomium, the palpi and the dorsal cirri 

 (pi. 60, figs. 1,2). 



The prostomium consists of a pair of papillated, lateral lobes that are 

 widely separated from each other by a smooth, median portion. Short 

 fusiform, papillated antennae are inserted at the frontal margins of the 

 lateral lobes. There are no eyes. Palpophores are thick and fleshy ; they 

 project beneath and in front of the prostomium and terminate distally in
