NO. 2 HARTMAN : POLYCHAETOUS ANNELIDS 255 



Glycinde armigera Moore 



G. multidens Hartman, 1940, pp. 249-251, pi. 44, figs. 126-131. 



This occurs in Tomales Bay and Bodega Lagoon, in muddy sand flats. 

 Length is 40 to 60 mm. This was earlier designated G. multidens (Hart- 

 man, 1940, p. 249). 



Family Eunicidae 

 Key to Species 



1. Peristomium with a pair of dorsal cirri . Eunice longicirrata 

 1. Peristomium without dorsal cirri . Marphysa stylobranchiata 



Eunice longicirrata Webster 



E. biannulata Moore, 1904, pp. 487-490, pis. 37, 38. 

 Hartman, 1944, pp. 141-146, pi. 6, figs. 118-122. 



At Tomales Point, ocean side, this occupies fragile, gravel-covered 

 tubes, on under sides of rocks. In life it is strikingly banded with red 

 and white transverse lines; acicula and subacicular hooks are yellow. 

 Prostomial antennae are articulate. Length is 50 to 80 mm. 



Marphysa stylobranchiata Moore 



Moore, 1909, pp. 249-251, pi. 7, figs. 8-12; Hartman, 1944, p. 174. 



At Tomales Point, ocean side, and at Second Sled Road, this is found 

 in crevices of soft shale rocks. Length is 100 to 200 mm. 



Family Onuphidae 

 Key to Species 



1. Branchiae strongly spiraled; tube coarsely covered with debris, 

 appears ragged, terminates distally in a lateral vent .... 

 Diopatra ornata 



1. Branchiae simple filaments; tube gray, mucoid, covered with a 

 thin layer of fine sand Nothria iridescens 



Diopatra ornata Moore 



Moore, 1911, pp. 273-277, pi. 18, figs. 77-85; Hartman, 1944, pp. 72- 



74, pi. 1, figs. 15-20. 



In Tomales Bay, at low-tide line, this is common in muddy sand flats. 



Tubes project a short distance above the surface. Length is 150 to 300 



mm, but individuals are seldom taken whole, since autotomy is conspicuous.
