NO. 1 hartman: goniadidae, glyceridae, nephtyidae 39 



O. eximia is characterized in having a prostomium with a large 

 basal, and 8 shorter distal annuli; there are 4 distal antennae; eyes are 

 lacking. The parapodial change from uniramous to biramous condition 

 occurs at segment 57 or 58, and is presumed to be abrupt. Notopodia 

 where best developed, have 8 to 10 simple pointed setae; neuropodia have 

 80 or more composite spinigers. 



The proboscis is covered with blunt organs (described as "kleinen, 

 schuppenartigen, stumpf kegelformigen Papillen"). The larger maero- 

 gnaths have 3 larger and a fourth small tooth. Micrognaths are ar- 

 ranged in a shorter ventral arc of 15 to 18, and a longer dorsal arc 

 of 19-22 pieces. 



O. eximia, sensu Monro (1936, pp. 141-143) from the Falkland 

 Islands, shore, seems to belong here. The specimen is 760 mm (nearly 

 30 inches) long and up to 13 mm wide without parapodia; it has over 

 258 setigerous segments. This is thus perhaps one of the largest gonia- 

 dids known. Macrognaths have 5 (not 4, as Ehlers stated) teeth and 

 micrognaths consist of 22 X-shaped pieces together with an accessory 

 series of smaller ones in a second row. The parapodial change is at 

 segment 59. 



Goniada eximia Monro (1937, p. 21) from abyssal depths in the 

 north Arabian Sea, is not the same but a species of Goniada (see above). 

 Goniada eximia Benham (1909) has been renamed Goniada maorica 

 Benham (1932). 



Ophioglycera distorta (Moore), new combination 



Goniada distorta Moore, 1903, pp. 461-464. 



This species is referred to Ophioglycera since it lacks chevrons. 

 Length of 106 segments (incomplete) is 66 mm; width in the anterior 

 region is 2.8 mm with, 2 mm without parapodia; width in posterior 

 segments is 3.7 mm with, 1.3 mm without parapodia. The prostomium 

 is annulate, with a long basal ring that is about Yz of the total length 

 of the prostomium, and 8 more distal annuli. Eyes are absent. The an- 

 terior uniramous part consists of 53 segments, but notosetae are not 

 present before segment 65. They are slightly curved, acicular, few in a 

 segment and heavier than the composite spinigers in neuropodia. 



Neuropodia consist of 2 presetal and one postsetal lobe of which 

 the dorsal presetal is slightly the longer, the postsetal one the shorter. 

 The ventral cirrus is large so as to extend beyond other lobes at the 

 posterior end of the uniramous part. The pharynx (proboscis retracted) 

 extends back to segment 42. Chevrons were not described and are
