NO. 1 hartman: goniadidae, glyceridae, nephtyidae 97 



Distribution. — Originally described from southern Alaska in 483 

 fms, the Gulf of Georgia in 31-90 fms and central California in 68-382 

 fms, it is here further reported from southern California in 54 to 263 

 fms. Berkeley (1942) recorded it from Alaska and British Columbia, 

 Canada.

Material examined. — Holotype specimen from Lota, Patagonia, de- 

 posited in the British Museum of Natural History, London, England. 



This species has remained unknown except through its original 

 brief description. The type consists of a single complete, though pos- 

 teriorly regenerated individual about 95 mm long. The prostomium 

 is approximately pentagonal in shape and broader than long, the width 

 about one and one-half times the length. The anterior margin is straight 

 and the posterior one broadly V-shaped. There are no visible eyespots 

 or other color markings. The protruded proboscis has 22 rows of 

 papillae (Baird described 12 pairs, or a total of 24). The subdistal 

 papillae are in 7 to 9 longitudinal rows; they decrease in size rapidly 

 in passing from distal to proximal regions; there is a moderatly large 

 middorsal papilla. The proximal surface of the proboscis is smooth. 



Interramal cirri are recurved (figs. 3, 4) not involute as first stated. 

 They are first present from the fourth segment and continued back to 

 the end of normal segments (the last 10 segments are regenerated). 

 Parapodia are well developed throughout; setae are numerous, long, 

 silky and flowing, but many are broken off obliquely near the base of 

 the spinous region. Preacicular lamellae are broad, flat and entire except 

 in anterior neuropodia where they are longer and slenderer. In about 

 the first 25 segments the superior edge of neuropodia has a conspicuous 

 lobe (fig. 3) ; farther back this lobe diminishes in size but is still visible 

 even in posterior segments as a small, digitate process (fig. 4).
