NO. 2 HARTMAN, BARNARD: BENTHIC FAUNA OF DEEP BASINS 97 



Glycera capitata branchiopoda Moore, 1911 



Glycera branchiopoda Moore, 1911, pp. 302-304, pi. 20, figs. 155, 156; 

 pi. 21, figs. 157-159. 



This species was taken in San Pedro, Santa Monica, Santa Catalina, 

 San Nicolas, East Cortes Basins and in the San Diego trough. It differs 

 from the stem species mainly in having longer parapodial lobes, especially 

 those of the dorsally and ventrally located pairs. Its distribution is 

 limited to deeper waters off southern California, whereas its nearly 

 related stem species is found in shallower depths. 



Glycera oxycephala Ehlers, 1887 

 Ehlers, 1887, pp. 121-123, pi. 41, figs. 7-11. 

 Hartman, 1950, pp. 70-71, pi. 10, figs. 3, 4. 



A single specimen was taken in Santa Barbara Basin. This is mainly 

 a shallow water form, usually present in sediments of red or brown 

 sand. It is more widely known on both sides of tropical America and 

 from California northward to Oregon. 



Glycera spp. 



Small fragmented or juvenile specimens come from San Nicolas, 

 and Tanner Basins and from the Patton escarpment. 



Family GONIADIDAE 



Genus GONIADA Audouin and Milne Edwards, 1833 



Goniada nr. brunnea Treadwell, 1906 

 Treadwell, 1906, p. 1174, figs. 67-70. 

 Hartman, 1950, pp. 17-19, pi. 1, figs. 1-6; pi. 4, fig. 1. 



One to several specimens each come from samples taken in San 

 Pedro, Santa Catalina, San Nicolas, Tanner, San Clemente, East Cortes, 

 West Cortes, Tanner and Long Basins, and from Patton escarpment 

 and the San Diego trough. They consistently differ from shallow water 

 representatives in having the transition from uniramous to biramous 

 parapodia at segments 32/33 to 35/36 instead of 44/45. The prostomium 

 has 8 annuli and the proboscidial chevrons are typical. Individuals usually 

 have reddish-brown bars across the segments and over parapodial bases. 

 In posterior segments the postsetal lobe is equally bifid, and in other 

 respects the resemblance is continued.
