NO. 1 HARTMAN : GONIADIDAE, GLYCERIDAE, NEPHTYIDAE 109 



and continued on successive segments to the end of the piece. Notopodial 

 postsetal lobes are foliaceous and broad (Augener, 1918, p. 165) ; acicu- 

 lar lobes are conical. 



Postacicular setae are long, smooth, pale. Preacicular setae are 

 barred as characteristic of other species. They were first thought ( Ehlers, 

 1887) to be lacking from neuropodia; however, they are present, most 

 conspicuous in anterior segments and diminish thereafter to only a few 

 in a segment. They thus resemble the ones in notopodia. 



This species seems to have its nearest affinities with N. incisa Malm- 

 gren, from which it is distinguished through the presence of the foliace- 

 ous notopodial lobes. 



Distribution. — This is recorded off southern Florida in 320-339 fms 

 (Ehlers, 1887, p. 131), off the West Indies in 44-197 fms (Augener, 

 1906, p. 154), off Delaware in over 600 fms (Treadwell, 1928, p. 

 466) and off Colombia, Atlantic side in 6 meters (Augener, 1933a, p. 

 209).

 California (2, collected by William Morton Wheeler). 



Total length exceeds 115 mm (posteriorly incomplete); number 

 of segments is over 120. The prostomium is trapezoidal in shape, the 

 anterior end only slightly wider than the posterior one; it is longer 

 than wide unless the proboscis is everted when it appears wider than long 

 (fig. 1). There are no color spots on preserved individuals. 



The proboscis has 22 bifid, terminal papillae. The subterminal ones 

 are arranged in 22 longitudinal rows and each row has few (one to 3), 

 the largest one distal and the greatest number at the sides of the pro- 

 boscis. In addition, there is a large, conspicuous middorsal one that 

 exceeds the others in size. The proximal surface of the proboscis is 

 smooth and glistening. 



Interramal cirri are recurved and first present from the sixth or 

 seventh segment; they are small through segments 10 to 16, and con- 

 tinued back nearly to the end of the body. The first 10 or more seg- 

 ments have parapodial rami widely separated, exposing a considerable 

 area of the interramal space (fig. 2) ; farther back the rami are less 

 widely separated.
