NO. 1 HARTMAN : GONIADIDAE, GLYCERIDAE, NEPHTYIDAE 99 



The first parapodium is biramous as are all others. Its ventral cirrus 

 is about as large as the ventral prostomial antenna; its dorsal cirrus is 

 smaller. The first notopodial fascicle, as also those of the next 3 seg- 

 ments, carries a series of long, backwardly directed barred preacicular 

 setae that far surpass the postacicular setae in their respective segments ; 

 those in the third and fourth segments are the most numerous and 

 longest; thereafter these preacicular setae diminish in importance. 



Interramal cirri are first present from the fourth segment, where 

 they are already large and far surpass the notopodial lobes in size. They 

 are clearly recurved and inscribe part of a spiral, already from the first. 

 These cirri are present through a long median region but absent from 

 some posterior segments. 



A superior neuropodial lobe is present from the fourth segment; it 

 is short at first but rapidly longer so that by the fifth it is conspicuous 

 (fig. 2) and continues so to the twelfth segment after which it diminishes 

 to absence before the thirtieth segment. It is not visible on median 

 segments. 



Notopodia have a large, foliaceous postsetal lobe, a slender, pro- 

 longed notopodial lobe, a short, broadly rounded acicular lobe in an- 

 terior segments that comes to be slightly equally bifid in median and 

 posterior segments. The single, yellow aciculum projects more or less 

 as a bluntly rounded straight rod. Notopodia of median and more 

 posterior segments tend to have a larger, broader, postsetal lobe and the 

 presetal part is correspondingly enlarged, but the differences are not 

 marked. 



Anterior neuropodia have similarly a large foliaceous postsetal lobe 

 that resembles its corresponding one in notopodia. At its superior edge 

 the digitate lobe is conspicuous only through about 12 segments; there- 

 after the postsetal portion comes to be very long, thin, extending dis- 

 tally nearly as far as the postacicular setae. The ventral cirrus is clavate 

 throughout, largest in median segments; it is occasionally, though 

 perhaps abnormally, bifurcated. 



Preacicular setae are transversely barred. Those of the first 4 

 segments are more conspicuous, coarser and longer than are the corres- 

 ponding postacicular setae. After the fourth segment they diminish in 

 thickness and size so as to be surpassed by the postacicular setae. The 

 transverse ridges of the barred setae are close (figs. 5, 6). 



Postacicular setae are flowing and arranged in fanshaped fascicles, 

 accompanied by single, straight yellow acicula. They are cylindrical in 

 their embedded basal portion; where they emerge from the fleshy 

 parapodium the stem is abruptly and obliquely thinner, appearing frac-
