Description. — Length uj) to 80 mm. Prosto- 

 mium conical; maxillae with Mx. I = 1 + 1; 

 II = 5-f5; III =2+2 (second tooth indistinct); 

 IV = 1 + 1. Parapodia with postsetal lobe longer 

 than presetal but shorter than setae even in 

 posterior feet. Compound spinigerous setae as 

 well a.s winged cai)illaries from first few feet 

 to about 25th. Compound hooks from about 

 18th to 30th foot and simi)le hooks thereafter. 

 Acicula pale.

 the first record from the United States.

Li( mbrineris atlantica. - Hartman, 1965a: 116, 

 pi. 19: Fig. A. * Day, Field, and Montgomery, 

 1971: 122. 



Description. — Body slender, 30-60 mm long. 

 Prostomium bluntly conical. Mandibular shafts 

 delicate and in contact throughout. Maxillae 

 with Mx. I = 1 + 1; II = (4-6) + (4-6); III = 

 1 + 1; IV = 1+ l.Mx. II usually with four or five 

 teeth but occasionally six (Hartman, 1942). Mx. 

 Ill as a cutting plate smaller than Mx. IV. 

 Anterior feet with a low presetal lobe and a 

 larger, compressed postsetal one. Middle feet 

 rather small with subequal presetal and post- 

 setal lobes. Posterior feet with longer lobes, 

 the presetal being obviously shorter than the 

 postsetal. Winged capillary setae from first foot 

 to middle feet. Hooded hooks from 12th-17th 

 foot or exceptionally from 9th (Pettibone, 1963a). 

 All hooks simple; anterior ones with long blades 

 but posterior ones with short blades and four 

 or more denticles above larger first tooth. Acicula 

 pale. 



Remarks. — I am indebted to Dr. Pettibone for 

 specimens of L. tennis and Dr. Hartman for 

 specimens of L. atlantica from 466 to 508 m off 

 Massachusetts, described in Hartman (1965a). 

 They appear to be identical though Dr. Hart- 

 man's illustration of the maxillae (pi. 19: Fig. a) 

 represents a form with four teeth on Mx. II 

 whereas the specimen I dissected had five teeth. 

 The difficulty is to decide what name should be 

 used. L. tennis Verrill has been well described. 

 L. atlantica Kinberg from La Plata has priority 

 but Kinberg's description was very brief; he 

 groups L. atkvitica with others having Mx. Ill 

 unidentate but his figure does not indicate this 

 and when Hartman (1948) reexamined the type 

 the jaws had been removed. Again Kinberg did 

 not figure the far posterior feet. Since there are 

 several closely related species some doubt must 

 remain as to whether the specimens described 

 by Hartman (1965a) off Massachusetts should 

 really be referred to L. atlantica. In view of this 

 I have retained the well established name L. 

 tennis. 



Records. — Common off Beaufort in 20 m 

 (21, *). 



Distribntion. — Maine to Florida; intertidal to 

 abyssal depths.
