NO. 1 hartman: goniadidae, glyceridae, nephtyidae 35 



The proboscis has 24 pairs of chevrons, the smallest piece at the 

 gnathal end, and increasing in size posteriorly. The distal end terminates 

 in 19 fleshy papillae. Macrognaths have 4 clawlike teeth each. Micro- 

 gnaths number 35 in the dorsal and 24 in the ventral arc; they consist 

 of pieces of varying sizes. The proboscidial organs are soft, have rounded 

 apex and are said to be varying in size; each has a pore near the apex 

 and a distinct groove on one side, running from the base to the apex. 



Distribution. — G. grahami is known only from off Otago, New 

 Zealand ; it was taken from stomach contents of a flounder. 



Goniada japonica Izuka 



Goniada japonica Izuka, 1912, pp. 232-234, pi. 23, figs. 1-6. 



A complete specimen of 327 segments is 225 mm long and 2.5 mm 

 wide with parapodia. Anterior uniramous segments number 76, followed 

 by 2 transitional segments; posterior biramous segments number 251. 

 Notosetae in biramous segments are few and acicular. 



The prostomium has 9 annuli. It terminates in front in 4 antennae 

 in which the ventral ones are slightly the larger; eyes have not been 

 noted. The proboscis has 18 pairs of chevrons. The distal end terminates 

 in 16 fleshy lobes. Macrognaths have 2 larger and 2 smaller clawlike 

 teeth each, or only 2 larger teeth. Micrognaths number 16 in the dorsal, 

 and 11 in the ventral arc. The proboscidial organs are described as 

 heart-shaped and leaflike, and are sparsely distributed in regular rows. 



Distribution. — This is known only from Japan. 



Genus Ophioglycera Verrill, 1885, revised 

 Type O. gigantea Verrill 



The body consists of 3 regions, an anterior one with uniramous 

 parapodia, a middle one in which notopodia are gradually developed, 

 and a posterior one in which parapodia are clearly biramous. Noto- 

 setae are simple, slender to somewhat acicular; neurosetae are composite 

 and spinigerous, far more numerous than notosetae and arranged in 

 fanshaped fascicles. The prostomium is conical and externally annulate, 

 the basal ring much the longer; the 4 terminal antennae are biarticulate. 

 The proboscis is long and cylindrical to somewhat clavate. It terminates 

 in front in a circlet of soft fleshy papillae within which is a circlet of 

 macrognaths and micrognaths. Chevrons are absent. The proximal sur- 

 face of the proboscis is covered with organs that resemble papillae, 

 but may be variously modified with structures resembling those in 

 Goniada (above).
