NO. 1 hartman: goniadidae, glyceridae, nephtyidae 19 



the dorsal one; another from station 1472-40 has 9 below and none 

 above; a large specimen may have 12 below and none above, and 19 

 pieces in each chevron. This indicated variation justifies the view that 

 the number of micrognaths and pieces in the chevron has little specific 

 significance in the species, G. brunnea. The same degree of inconstancy 

 has not been reported in other species, to my knowledge. 



Parapodia are characteristic, especially in posterior segments. The 

 dorsal cirrus is large, broad and foliaceous, and has a slender base (figs. 

 2, 3). The notopodium consists of a long, triangular, prestal lobe that 

 nearly equals the dorsal cirrus in length, and a much shorter, lower 

 postsetal lobe. Notosetae consist of thick, pointed setae with 11 or 12 

 in a fascicle. Acicula occur singly and are translucent yellow; they do 

 not project from the parapodium. 



Neuropodia are longer and heavier than notopodia. They consist of 

 2 long, triangular, presetal lobes that resemble the ventral cirrus but 

 are flatter. The superior part tends to be longer than the inferior one 

 or the 2 may be subequal. Neurosetae are entirely composite spinigerous; 

 they number about 22 in a fascicle. They are slenderer than the noto- 

 setae. Anal processes are 2 long, slender filaments. 



G. brunnea resembles G. maculata (see below) and was earlier 

 (Hartman, 1940, p. 251) thought to be the same. Both species are 

 maculate, have similar parapodial parts and comparable proboscidial 

 organs. Both have a broad, depressed prostomium. In G. brunnea, how- 

 ever, the dorsal cirri are broader than in G. maculata and the noto- 

 podium has a short, postsetal lobe that is absent from G. maculata. 

 G. brunnea approaches G. eximia Ehlers in its gross features but the 

 latter is here referred to Ophioglycera Verrill (below). 



The numerous individuals listed above are referred to this species 

 as interpreted by Moore (1911) and not as in the original (Treadwell, 

 1906) account. The latter is wanting in many respects and the pro- 

 boscis remains altogether unknown. 



Three specimens reported as G. annulata (Treadwell, 1914, p. 198) 

 dredged off southern California, have been examined and are here 

 referred to G. brunnea; these specimens are now deposited in the Allan 

 Hancock Foundation. 



Distribution. — This occurs commonly in the Eastern Pacific Ocean 

 from Alaska south to southern California and possibly in Hawaii; 

 depths range from low intertidal to over 600 fms.
