 Fig. 1-12. - Pettibone, 1963a: 22, Fig. 5h-j. 



Records. — Planktonic in tiie Gulf Stream (17). 

 DistribHtioii. — Gulf Stream from Bermuda 

 to Massachusetts; 0-1,800 m. 



Lepidonotus sublevis Verrill, 1873 



LcpidoiiotKs sublevis. - Hartman, 1942a: 22. 

 Fig. 7-12. - Pettibone, 1963a: 18, Fig. 3 e. 



Records. — Several records between and 

 100 m off North Carolina (5, 11, 15, 17, 18, 21, *). 



Distribution. — Massachusetts to Florida and 

 the Gulf of Mexico; intertidal to 100 m. Often 

 commensal with hermit crabs. 



Lepidonotus variabilis Webster, 1879 



Lcpidoiiofiis rdj'ia/iilis Webster, 1879: 

 Hartman, 1951: 18 (notes). 



205. - 



Remarks. — This species is close to L. tomi- 

 setosus Gravier from the Red Sea. 



Records. — Many records from the shore to 

 18 m off North Carolina (3, 5, 11. 13. 15, 18. 20). 



Distribution. — Virginia to the West Indies; 

 intertidal to a few meters. 



Lepidametria commensalis Webster, 1879 



Lepidametriti roniniensdlis. - Seidler. 1924: 148.

 196.3a: 19. Fig. 4 k. 



Ri uiiirh-s.^ln Day (1962: 634) 1 gave my 

 reasons for regarding Lepidametria as a .syno- 

 nym of Lepidastlieiiia. Dr. Pettibone, who is 

 making an intensive .study of the Polynoidae, 

 informs me that Lepidametria is a valid genus 

 and in deference to her opinion I have not 

 changed the name of Lepidametria commoisulis. 



Records. — Many records from the shore to 

 24 m off North Carolina (3, 5, 11, 13. 15. 17, 18). 



Distribution. — Ma.ssachusetts to Florida and 

 the Gulf of Mexico; intertidal to 24 m. 



Lepidasthenia sp. 



FifTure le, f 



Description. — Lateral antennae about equal 

 to median and 1.7 times prostomial length. 

 Occipital flap semicircular with a smooth mar- 

 gin. Elytra smooth, half brown and half pale, 

 not large enough to cover middle of dorsum. 

 Notosetae absent. Superior neuro.setae (Figure 

 le) slender, ending in blunt tips; inferior neuro- 

 setae (Figure If) stout and bidentate with a 

 small .secondary tooth. Ventral margins of para- 

 podia without pajiillae. 



Remarks. — Only a single incomplete speci- 

 men with 23 segments was obtained. It resem- 

 bles L. I)rnnnea Day. from South Africa in the 

 pigment pattern on the elytra, in the absence 

 of notosetae and in the shape of the neurosetae. 

 It differs in having a well-developed occii)ital 

 flap and the lack of a row of papillae on the 

 ventral margins of the neuropodia. It may be 

 noted that Lepidametria brunneu Knox. (1960: 

 91. Fig. 58-63) is also similar. The description 

 of Knox's species was published later than that 

 of Day. 



Records. — Off Beaufort in 120 m; one speci- 

 men (*).

 Snbadytc pelhtcida. - Pettibone, 1969: Fig. 4a-e. 



Description. — Body 8-15 mm long with about 

 45 segments, very fragile and mottled with 

 greenish grey. Prostomium bilobed but without 

 anterolateral peaks. Lateral antennae inserted 

 ventrally at a lower level than median. All three 

 antennae much longer than prostomium. Fif- 

 teen pairs of large, delicate and deciduous elytra 

 covering entire body. Individual elytra with 

 minute marginal papillae and conical micro- 

 tubercles scattered over surface. Dor.sal cirri 

 long with slender tips. Noto.setae fairly .stout 

 with a few coarse serrations and blunt tips. 

 Neurosetae (Figure Ig) long and very trans-
