NO. 1 hartman: goniadidae, glyceridae, nephtyidae 27 



The first few parapodia agree closely with those described for G. 

 magna (below). Notosetae are first present from setigerous segment 33; 

 notopodia increase in size gradually through a long region so that by 

 segment 85 the full size of parapodia is attained. Dorsal cirri are long 

 and foliaceous. Notosetae are numerous in a fascicle and hairlike. 



Parapodia are maculate in the posterior region ; large dark areas are 

 segmentally seen over the upper parapodial base, dorsal cirrus, presetal 

 and postsetal lobes and ventral cirrus. The body cavity of this specimen 

 is crowded with large ova. 



On the type specimen of Goniada magna the distal end of the pro- 

 boscis is dissected out and partly cut away. There are 21 pairs of chev- 

 rons, each patch an elongated oval with the smallest pieces at either end ; 

 the pieces are set close together but clearly separated from one another. 

 The terminal papillae have been cut, but may number 16 or more. 

 Macrognaths have 5 teeth each, gradually increasing in size; these were 

 first described as "three-pronged denticles" since the 2 smallest teeth 

 were embedded. Micrognaths are arranged in dorsal and ventral arcs 

 that resemble one another; each has 20 or more pieces in an irregular 

 double row. Since the proboscis is retracted they are crowded together. 

 The proboscidial organs are small, closely set, and thickly strewn over 

 the surface, but denser on the dorsal side, sparser on the ventral side. 

 All are of one kind except that the dorsal ones are larger than the ven- 

 tral ones. They agree exactly with those of G. quinquelabiata Augener 

 (above). 



The prostomium consists of a long, basal ring over half as long as 

 the rest of the prostomium; it has transverse nuchal slits at the sides at 

 about its midlength. This ring is unique for having at its sides, in line 

 with the lateral parapodia, a pair of small foliaceous lobes that resemble 

 a dorsal cirrus. The shorter, more distal prostomial rings are more 

 depressed, number 8 counted at the sides, and the 7 distalmost are again 

 weakly transversely divided on the dorsal side. All transverse rings are 

 obscure on the ventral side. The distalmost is truncate in front; it has 

 a pair of frontal, and a pair of more posterior, dorsolateral antennae. 

 The first pair is only about half as large as the second. Each is biarticulate, 

 with a larger basal, and a tiny, papillar distal article. No eyespots are 

 visible. 



The first parapodium consists of 3 long, triangular pointed lobes; 

 its ventral cirrus is much the longest; its dorsal cirrus is flattened and 

 the setal lobe is conical. This segment carries a small fascicle of setae. 

 The second parapodium is similar to the first, but larger and its presetal
