diagnostic. The proboscidial organs are unique in being tall and slender ; 

 their oral side is clearly ridged with 9 or 10 transverse ridges (fig. 4) 

 and there is no apparent midrib. The distal end is slightly beaked (fig. 

 3) toward the oral aperture and there is a long canal leading to a 

 large, clear cell with a tiny dark spot within. 



Earlier, I (Hartman, 1940, p. 248) questionably referred to this 

 species and now follow the same interpretation in designating the speci- 

 mens enumerated above, even though Ehlers' (1887) original account 

 is not clear on some points. 



G. verdescens Chamberlin (1919b, p. 14) from Laguna Beach, 

 California is here questionably referred to G. oxycephala Ehlers. The 

 brief description, without illustrations, was based on a single, caudally 

 incomplete individual, only 13 mm long for 69 segments, and was 

 thus possibly a juvenile stage. A type specimen is not known to exist. 

 The proboscis was not described. In so far as the description goes, it 

 agrees with the specimens listed above in that the prostomium is similar- 

 ly conical and slender; parapodial lobes appear to be the same, and its 

 origin falls within the range of present materials. 



Distribution. — G. oxycephala Ehlers is recorded from both sides 

 of tropical America. Its range is here extended northward to California 

 with its outlying islands, and Coos Bay, Oregon. Bathymetric range 

 is subintertidal to 61 fms.

The proboscidial organs (figs. 1,2) ally this species to G. oxycephala 

 Ehlers. They are tall and slender, with 13 or 14 (rarely to 16) trans- 

 verse ridges on the oral side, the 2 of a pair meeting medially. The distal 

 aperture may be wide open (fig. 1) or considerably constricted. It 

 leads internally to a long canal and a large cell near the base. The 

 external ridges pass well around the sides so that in side view (fig. 2) 

 they appear corrugated. In their tall, slender proportions they agree 

 more nearly with what has been shown for G. serrulifera (Ehlers, 

 1908, pi. 14, fig. 16) than with those of any other species. 



Glycera sp., ? juv., reported by Treadwell (1914, p. 198) from 

 San Diego Bay, California, belongs here. The collection contains 2 

 individuals, taken from coarse yellow sand and broken shells in 2-3 

 fms ; the specimens are now in the Allan Hancock Foundation.
