smooth surface; there is usually a small dark spot over the elytral scar 

 and a larger dark area on the inner or also posterior portion (pi. 20, fig. 

 10). The elytrophoral scar is elongate in anteroposterior direction. 

 Nephridial papillae are inconspicuous, directed upward between the bases 

 of parapodia, from the ventral side. In life the color is pale except for 

 dusky patches on elytra and cirri. 



H. lunulata and its several varieties (see Fauvel, 1923) have been 

 reported from widely scattered areas of the Atlantic and Mediterranean 

 seas. Recently Monro (1928, pp. 559-560) described a variety, pacifica, 

 from the Galapagos in 4 to 6 fms. Berkeley (1941, p. 21) recorded the 

 species from southern California. It has been described as both free living 

 and commensal, with holothurians or other chaetopods, notably species of 

 Marphysa, Arenicola, Polycirrus, and Mesochaetopterus. The individuals 

 from Tomales Bay were taken from the burrows of a holothurian. 



Family Ghrysopetalidac 

 Paleanotus chrysolepis Schmarda 



Heteropale bellis Johnson, 1897, pp. 163-164, pi. 6. 

 Hartman, 1940, p. 201. 



At Tomales Point, ocean side, it occurs among Bryozoa and sponge 

 masses. Length is 10 to 15 mm. 



Family Amphinomidae 

 Pareurythoe calif ornica (Johnson) 



Eurythoe californica Johnson, 1897, pp. 159-161, pi. 5. 

 Hartman, 1940, p. 203. 



At Tomales Point, ocean side, it is under stones and in crevices. 

 Though common in southern California, it is seen only occasionally in 

 central California. It is the only known representative of this family in 

 these northern latitudes. Length is 30 to 40 mm. 



Family Hesionidac 



Podarke pugettensis Johnson 



Johnson, 1901, pp. 397-398, pi. 3; Hartman, 1940, p. 211. 



At Tomales Point, ocean side, it is commensal with Patiria miniata 

 (Brandt) or species of Pisaster; it is sometimes free living, under stones. 

 In life it is dark purplish brown. Length is 12 to 20 mm.
