NO. 3 HARTMAN : POLYCHAETOUS ANNELIDS 253 



basal portion, that is about four times as long as wide, and a distal, slen- 

 der, papillar style. 



The proboscis (protruded) is long, cylindrical, widest distally. It has 

 a series of chevrons on either side, near the base, consisting of 10 to 12 

 pieces in a set (pi. 44, figs. 138, 139). There are 17 soft, terminal papil- 

 lae. Macrognaths are black, with 5 claws, decreasing in size from dorsal 

 to ventral ends, the dorsalmost about 6 times as long as the ventralmost. 

 Micrognaths include 17 in the dorsal arc and 13 in the ventral. They 

 form a continuous series, but vary somewhat in size. Some of the larger 

 are accompanied, on their outer side, by an accessory smaller piece similar 

 to the larger, and functioning, perhaps, to replace the older when lost. 

 Each of the micrognaths has 2 terminal points and 2 embedded teeth. Pro- 

 boscidial papillae are of one kind, distally truncate (pi. 44, fig. 135), but 

 in lateral view are seen to be directed away from the terminal jaw pieces 

 (pi. 44, fig. 134). 



Parapodia in the anterior region have well-developed lobes and cirri, 

 the ventral cirrus exceeding the other lobes in size (pi. 44, fig. 132). 

 From about the sixty-fourth parapodium, the notopodium is present as a 

 slender, digitate lobe, and within it are embedded 2 dark, acicular setae. 

 The dorsal and ventral rami are not separated ; hence this region is apt to 

 remain unobserved. Parapodia of the median region have notopodia con- 

 sisting of an upwardly directed, postacicular and a preacicular lobe (pi. 

 44, fig. 137). The ventral cirrus continues large, long, surpassing the 

 other parapodial lobes. Parapodia of the posterior region have the rami 

 well separated. The postacicular neuropodial lobe is broadly rounded, 

 somewhat obcordate (pi. 44, figs. 133, 136), surpassed by the slender, bi- 

 furcated presetal lobe (pi. 44, fig. 136). Neuropodial setae are numerous, 

 disposed in fan-shaped fascicles, the articulation heterogomph (pi. 44, fig. 

 141). Notopodia consist of 2 subequal lobes, provided with a few (3 to 

 5) stout, acicular setae with blunt, slightly bent tip (pi. 44, fig. 140). 

 Their surface is smooth, not granular or serrated. They are about as thick 

 as the supporting acicula. Setae and acicula are pale amber in color, the 

 composite setae nearly colorless. 



Goniada acicula has the stout acicular notopodial setae characteristic 

 of some other species. From G. grahami Benham (1932, p. 561) from 

 New Zealand, it differs in that the notopodial acicula are amber colored, 

 not black; the stout notopodial setae are distally curved, not straight. 

 From G. teres Treadwell (1931, p. 19) from Jamaica, it differs in that
