NO. 1 hartman: goniadidae, glyceridae, nephtyidae 21 



The single individual is incomplete posteriorly and in 2 pieces 

 but probably only a short, posterior end is missing. The proboscis is 

 everted about a third of the way. The prostomium is uniquely annulated, 

 as originally stated; it has few rings, numbering only 5 ventrally and 

 4 dorsally (fig. 1). The anterior antennae have been torn away from 

 the individual but in other respects the prostomium is complete. There 

 is no indication of eyespots. 



The proboscis is long and cylindrical. Its distal end terminates in 

 soft papillae. Paragnaths consist of a pair of large macrognaths with the 

 largest teeth on the dorsal end. Micrognaths include 15 in the dorsal, 

 and 7 in the ventral arc. The chevrons at the sides, near the base, num- 

 ber 16 pieces on the right, and 20 pieces (fig. 2) on the left side; they 

 are broadly V-shaped and very close together, resembling a solid dark 

 mass when seen under low magnification. 



The proboscidial organs are largest along the distal portion of the 

 proboscis and diminish gradually basally as also in the grooves marking 

 the longitudinal neural bands. They are of one kind but vary in size. 

 All are tall, translucent cones, slightly beaked (fig. 9) toward the 

 prostomial end and there is a subcorneal pore (fig. 8) that leads intern- 

 ally to a canal and externally to a furrow to the base of the organ. 

 The base is usually bluntly equitriangular, but some organs that are 

 shrunken appear slightly lobed at the base and hence might be thought 

 to have a trilobed base, as Moore (1905) described. A large, nearly 

 clear cell can be seen near the base of the organ. In structure and per- 

 haps function these organs are much like those of G. brunnea (above) 

 except that these lack the flaring outer membrane and are taller. 



The parapodial change occurs at segment 34 and is more or less 

 abrupt. Dorsal cirri are broadly foliaceous (figs. 3, 4). Notopodia con- 

 sist of a longer, pointed presetal portion and a shorter, postsetal one. 

 Neuropodia have a bilobed presetal portion that exceeds the single, 

 postsetal lobe. In median segments the superior portion of the presetal 

 lobe is the longer and distinctly rounded (fig. 4) ; farther back the 

 2 parts tend to be about equally long (fig. 3). In median and posterior 

 parapodia the ventral cirri are inserted far proximal and do not extend 

 distally to the end of neuropodial lobes. 



Acicula are single and translucent yellow in color. They do not 

 project beyond the parapodial lobes. Notopodial setae are simple, slender, 

 distally pointed and number 8 to 12 in a fascicle. Neuropodial setae 

 are composite spinigerous and far more numerous than notosetae (fig. 

 4). The shaft is approximately cylindrical through most of its length, but
