59), length is 30 mm, width 1.2 mm and segments number more 

 than 100, The body is smooth, linear and there are no visible branchiae. 

 The first ring is smooth, vv^ithout parapodia. The thorax consists 

 of 12 segments of which 11 are setigerous (Hartman, 1947, p. 402); 

 the first 6 notopodia have only setae, the next one has mixed setae 

 and hooks and the last 4 have long handled hooks. Thoracic neuropodia 

 have setae in the first 8 segments and hooks in the last 3 segments. 

 The formula may be expressed as follows: 



I ( 6 s + 1 mixed + 4 h 

 penstommm + < 



( 8s + 3h 



The prostomium is transversely divided into a small, globular palpode 

 and a posterior, shorter though wider part ; there are no visible eyes. 

 The peristomium is about as long as the next segment but somewhat 

 narrower. The everted proboscis is globular and covered with in- 

 conspicuous low papillae. The thoracic region is smooth, not reticulate 

 and broadest in the region of the second setigerous segment. Separa- 

 tion between thorax and abdomen is visible as a groove, because the 

 body is abruptly wider in the abdomen. 



The only other species in the genus is Barantolla sculpta Southern, 

 from Salt Lake near Calcutta, India, in brackish, shallow water. This 

 differs from B. americana in having the thorax reticulated, segments 

 with a membranous collar from which parapodial lobes originate, and 

 branchiae present.
