of the appendage) it is serrated, thence slopes gradually at the sides to 

 a concave back. These setae usually lie so that the articulation is twisted 

 and seen in three-fourths view (fig. 8). The appendage has several (to 

 7 or 8) longitudinal rows of teeth. They are continued distally almost 

 to the slender, pointed tip and basally nearly to the articulation. The 

 teeth are arranged in trim, transverse rows (fig. 6). In cross section the 

 appendages are somewhat oval (fig. 7) with the teeth arranged on the 

 widest end of the oval. Although the number of teeth in a row is about 

 the same near the base as near the tip, those distally are gradually 

 slenderer and longer than those near the base. 



Anal processes consist of a pair of long, slender, distally tapering 

 structures that are about as long as the last 10 segments; they are 

 inserted ventral to a pygidial papilla. In mature female individuals, ova 

 occur first at about segment 48 and they are continued posteriorly in 

 segments nearly to the end of the body. In this region they are numerous, 

 closely packed, causing an extension of the body wall. In mature male 

 individuals the spermaries are first present at about segment 43 and 

 continued to near the end of the body. Epitokous individuals have not 

 been observed. 



G. littorea is characterized especially for the unique proboscidial 

 organs and for the arrangement of micrognaths in that there are more 

 in the dorsal, than in the ventral arc. The parapodial lobes of posterior 

 segments are also specific. This species was earlier (Hartman, 1940, p. 

 252) recorded from southern California as G. uncinigera Ehlers (1901, 

 p. 159) but the 2 are now believed to be distinct. The latter is poorly 

 known ; it originates from Corral, southern Chile in 5-6 fms. Its account 

 was based on a single tiny individual only 13 mm long and consisting of 

 110 segments. Uniramous parapodia number about 39. The prostomium 

 has only 7 rings. Chevrons of the proboscis number about 13 dark 

 pieces on a side. The description is not clear concerning the structure 

 and distribution of proboscidial organs. They were described as "von 

 ungleicher Form und in ungleicher Dichte besetzt." Those from the 

 middle of the proboscis are shown with a sharp, angled bent process 

 directed orally and at its base there are 2 short, lateral processes. Near 

 the oral end of the proboscis these organs are said to be blunt, with a 

 short, abrupt point. The micrognaths are said to comprise 3 in the 

 dorsal, and 9 in the ventral arc. 



Although G. littorea and G. uncinigera are perhaps more nearly 

 allied to each other than to other known species of the genus (especially 

 because of the peculiarities of the proboscidial organs) there are sharp 

 differences separating them, as shown above.
