Rec()fd><. — Virginia to Beaufort, intertidai (11. 

 17). 



Distrihiitid)/. — Cosmopolitan in temperate 

 and tropical seas; intertidai to 100 m. 



Lumbrineris sp. 



Description. — Length 10-15 mm. Pro.stomium 

 conical. Mandibular shafts in contact through- 

 out. Mx. I = 1-1-1; Mx. II = 4 4-4 (or 3-1-3 in 

 small, 10-mm specimens); Mx. Ill = 1 -I- 1 (cut- 

 ting plates smaller than Mx. IV); Mx. IV = 1-f-l. 

 Anterior feet with a low presetal lobe and a 

 longer postsetal one; middle feet small with 

 pre- and postsetal lobes subequal; posterior 

 feet with postsetal lobe definitely longer than 

 presetal one. Winged capillaries from the first 

 foot to middle of body. Simple hooks with very 

 elongate blades resembling broken-tipped cap- 

 illaries from third or fourth foot to about 20th 

 and short-bladed hooks thereafter. Acicula pale. 



Rcmarkfi. — These small specimens do not 

 quite fit any known species and may be juve- 

 niles whose characters change later. In L. tenuity 

 the hooks appear in the 12th-17th foot. In L. 

 brivicirra Schmarda, recorded from South Africa, 

 Au.stralia, New Zealand, Chile, and Japan, Mx. 

 II has five teeth but the other characters are 

 similar. 



Ri cords. — Twenty-three specimens in 40-200 

 m off Beaufort (21, *).

DcKcription. — Body fairly stout, up to 75 mm 

 long. Prostomium broadly conical. Mandibles 

 characteristic with broad divergent shafts form- 

 ing a rough X. Maxillae with Mx. I = H-1; 

 II = 3-f 3 (large stout teeth); III = 1-I-1;IV = 

 1 -I- 1 (very large white plates with black margins). 

 Anterior feet with well-developed presetal lobes 



and slightly longer and broader postsetal ones; 

 middle feet with subequal lobes; posterior feet 

 with equal tapered lobes curving upward but 

 not as long as setae. Winged capillaries from 

 first foot to middle of body. Four to five com- 

 pound hooks from first foot to 12th-17th and 

 simple hooks thereafter. Acicula jnile.

 (21, *); This is a new record for the United 

 States.

 chald, 1970: 83, pi. 12; Fig. g-j. 



Description. — Pale, slender worms 35 mm 

 long by 0.7 mm for 150 segments. Prostomium 

 (Figure 9a) bluntly conical. Mandibles (Figure

 tinized;Mx.I = 1-1-1; II = 4 -1-4 (in exceptional 

 ca.ses 3-1- 3 or 5-1-5); III = 1 -I- 1 (curved cutting 

 plates); IV = 1 -I- 1 (larger plates than Mx. III). 

 Anterior feet (Figure 9g) well developed, each 

 with a low presetal lobe and a compressed, oval
