NO. 2 HARTMAN : POLYCHAETOUS ANNELIDS 271 



Subfamily Amphitritinae 

 Terebella californica Moore 



Moore, 1904, pp. 496-498, pi. 38, figs. 36, 37. 



At Tomales Point, ocean side, 2 specimens were taken by R. E. Paul- 

 son. It is pale red in life. Length is 60 to 80 mm, but the body is usually 

 more or less coiled. 



Eupolymnia crescentis Chamberlin 



Chamberlin, 1919, pp. 265-266, pi. 3, figs. 6, 7. 



In Tomales Bay this is common in muddy sand flats. Color in life 

 is dull green with reddish cast. Length is 90 mm or over. 



Loimia montagui (Grube) 

 PIate21, Fig. 28 



Terebella montagui Grube, 1878 (not Quatrefages, 1866, p. 361). 

 Berkeley, 1941, p. 54. 



In muddy sand flats of Tomales Bay this occupies fragile, chitinized 

 tubes, covered with coarse sand or gravel particles. It is greenish in life, 

 but has a bright red area along the conspicuous ventral thoracic scutes; 

 it has 2 pairs of large lateral lappets at the anterior end of the thorax. 

 Uncini have teeth in pectiniform arrangement, the thoracic uncini with 

 5 or 6 teeth, the abdominal with 6 (pi. 21, fig. 28) or 7 teeth. Length is 

 75 mm or over. 



Although the specific name is preoccupied (see synonymy above), it 

 seems unnecessary to apply a new name, since Grube's species has been 

 referred to a different genus. This species has previously been reported 

 from Elkhorn Slough (MacGinitie, 1935, p. 696) and from southern 

 California (Berkeley, 1941, p. 54). 



Genus RAM EX, new genus 



Branchiae consist of a single pair, dichotomously branched several 

 times. The peristomial ring has numerous eyespots. Anterior segments 

 lack lateral lappets. Thoracic setigers number only 13. The first para- 

 podium immediately posterior to the branchial ring is represented only 

 by a papilla lacking setae. The first setiger has notosetae only; the next 

 segment has a notopodial fascicle and uncinigerous torus. Setigers 3 and 

 4 have prolonged digitate, nephridial papillae, directed upward. Thoracic 

 setae are distally smooth, narrowly bilimbate. Uncini are avicular, thick, 

 with a major tooth and several rows of fine teeth. Thoracic uncini occur 

 in single series on the first 6 tori, thereafter in alternating rows. 



Type of the genus is R. calif or niensis, new species.
