NO. 1 hartman: goniadidae, glyceridae, nephtyidae 77 



If the cold and warm water Pacific forms are distinct species, which 

 I doubt, the specific name, G. nana Johnson (1901, p. 411) is to be 

 retained for the northern group, the others go to G. capitata Oersted. 

 The presence of intergrading individuals is an argument against such 

 usage. 



Hemipodia canadensis Treadwell (1937a, p. 348) from Nova Scotia, 

 Canada, has both simple and composite setae, thus is not a species of 

 Hemipodus Quatrefages. Its parapodial lobes resemble those of G. 

 capitata Oersted, and in other respects, in so far as the description goes, 

 it agrees with the latter. 



Distribution. — G. capitata Oersted is known from temperate and 

 cold waters of the northern hemisphere. It occurs on both sides of the 

 north Atlantic and along the eastern shores of the north Pacific. The 

 collections recorded above come from Alaska south to southern Cali- 

 fornia and the Gulf of California, Mexico ; depths range from shore to 

 250 fms.

 of California, Berkeley. 



Proboscidial organs are of a single kind but they differ among them- 

 selves as to size. All are long and slender so that the everted proboscis 

 appears pilose. Under high magnification, with the aid of reflected light, 

 the surface details can be distinguished. The organs are slightly beaked 

 at the tip, and the distal aperture is directed away from the jaws. The 

 surface is longitudinally grooved, the grooves marking the spaces be- 

 tween internal strengthening fibers. Each organ has 3 long, translucent
