NO. 2 HARTMAN : POLYCHAETOUS ANNELIDS 285 



Another one from Tomales Point, ocean side, in rock crevices, was 

 collected by George M. Good. It differs from the others in totally lack- 

 ing eyespots on the radioles; there is no pigment (preserved). E. tenella 

 Bush (Hartman, 1942, p. 86) is the only known Eiidistylia lacking eye- 

 spots, but it too is questionably separable from E. vancouveri. Since the 

 distribution of eyespots is very irregular on all specimens and their 

 number on any one or all radioles not predictable, it seems that this 

 character has little or no specific value.

Two individuals were taken from Tomales Point, ocean side, in rocky 

 crevices. Tubes are thick, leathery, externally covered with fine sand 

 grains. The body (preserved) is white or pale, the tentacular crown 

 reddish brown, heavily mottled so as to appear velvety or fuzzy. The 

 tentacular base is not spiraled as in species of Eudistylia, but the ventral 

 edge is somewhat rolled in, giving an impression of slight spiraling. There 

 are no true eyespots. 



The collar consists of a pair of low, oblique dorsal lobes, and longer 

 lateral lobes terminating ventrally in a pair of triangular ventral flaps. 

 There are middorsal and ventral, and deep, wide, dorsolateral incisions. 

 Thoracic notosetae include longer, narrower ones in the superior part of 

 the fascicle, and somewhat shorter, broader, though similar ones (pi. 23, 

 fig. 42) inferiorly; neurosetae consist of an anterior row of pennoned 

 setae and a posterior row of avicular hooks. Abdominal parapodia are 

 provided with avicular hooks in notopodia and limbate setae in neuro- 

 podia. Length is 35 to 55 mm.
