western Florida. Occurs in crevices, under stones, in 

 ascidian and sponge masses. Elsewhere known from 

 eastern United States. 



4. Halosydna leucohyha Schmarda, 1861. 



Recorded by Rioja, 1946, p. 193, from Veracruz, 

 Mexico, from between calcareous algae and niollusk 

 shells. Elsewhere known from the West Indies and 

 Bermuda. 



5. Harmoihoe aculeata Andrews, 1891. 



Reported by Hartnian, 1945, p. 10, from Lemon Bay 

 southwestern Florida, under stones, in crevices, and on 

 piles. Elsewhere known from North Carolina and 

 Maryland. 



6. Harmoihoe aculeata (Treadwell), 1924. 



Recorded by Rioja, 1946, p. 193, from Tecolutla, 

 Mexico, from moUusk shells. Otherwise known from 

 Barbados and Antigua, West Indies. 



Family SIGALIONIDAE 



*7. Sthenelais ? articulala Kinberg, 1855. 



As Eupholoe globosa Winternitz, 1936, p. 3, figs. 6-12, 

 from Apalachicola, Florida. This is here newly refsrred 

 to the genus Sthenelais and questionably to the species 

 articulata Kinberg. As the latter, it is known also from 

 Brazil and the West Indies. 



Family AMPHINOMIDAE 



8. Amphinome rostrata (Pallas), 1766. 



Reported by Augener, 1922, p. 39, from Veracruz, 

 Mexico, and Campeche Bank, Gulf of Mexico, on floating 

 logs. Widely recorded from Brazil northward through the 

 West Indies and Gulf Stream to North Carolina. 

 *9. Hipponoe mullibranchiata (Treadwell), new com- 

 bination. 



As Metamphinome multibranchiata Treadwell, 1940, pp. 

 1-2, figs. 1-3, from Galveston, Texas, on a floating log. 

 This species is clearly separable from the nearly related 

 Hipponoe gaudichaudi Audouin and Milne Edwards, 

 known from the Gulf Stream, for having branchiae that 

 are continued far back. 



Family PHYLLODOCIDAE 



10. Eteone heteropoda Hartman, 1951. Pub. Inst. Mar. 



Sci. 

 From Biloxi, Mississippi, sandy mud flats, also western 

 and northwestern Florida and southeastern Texas, in 

 sandy flats in littoral zones. Not taken outside of the 

 Gulf" 



11. NereiphiiUa fraijilis (Webster), 1879. 



Recorded by Hartman (1951, Pub. Inst. Sci.), from 

 Lemon Bay, Florida, and Port Aransas, Texas, from 

 oyster and ascidian clumps. Phyllodoce unirirrata Win- 

 ternitz, 1936, pp. 1-3, figs. 3-5, from Apalachicola, 

 Florida, may be the same. Otherwise known from eastern 

 United States. 



12. Eiimida sanguinea (Oersted), 1843. 



Recorded by Hartman (1951, Pub. Inst. Sci.). Among 

 shells, stones, in circummundane littoral zones. 



Family PILARGIIDAE 



13. Ancistrosyllis bassi Hartman, 1945. 



Reported from Englewood, Florida, by Hartman, 1945, 

 p. 15, and described by Hartman, 1947, pp. 501-504, pi. 61, 

 from the Gulf of Mexico, North Carolina, and San Fran- 

 cisco Bay, California, in low or subintertidal sand flats. 



14. Loandalia americana Hartman, 1947. 



Described by Hartman, 1947, pp. 506-509, pi. 63, from 

 Biloxi, Mississippi, Grand Isle, Louisiana, and elsewhere 

 off San Jos6 Light, Guatemala, Pacific Ocean; in sand, 

 littoral. 



Family SYLLIDAE 



15. Autolytus brevicirrata Winternitz, 1936. 



Known only through the original description, Win- 

 ternitz, 1936, p. 1, figs. 1-2, from Apalachicola, Florida. 

 Incompletely characterized. 



16. Typosyllis coraUicoides Augener, 1922. 



As Syllis {Typosyllis) coraUicoides Augener, 1922, pp. 

 42-43, from Veracruz, Mexico, and not otherwise known. 



Family NEREIDAE 



17. Neanthes succinea (Frey and Leuckart), 1847. 

 Reported by Rioja, 1946, p. 194, and pp. 205-206, from 



Tecolutla and Veracruz, Mexico, from mangrove swamps 

 associated with barnacles. Widely recorded from estua- 

 rine regions of tamperate and subtropical regions of cir- 

 cummundane areas. 

 *18. Nereis largoensis Treadwell, 1931. 



First described as Nereis brevicirrata Treadwell, 1929, 

 pp. 3-4, figs. 1-4, from Key Largo, Florida (not Nereis 

 brevicirrata Treadwell, 1920, pp. 467-468, figs. 1-4, from 

 Santos, Brazil, which is, however, a species of Perinereis). 

 This was later reported from Grand Isle, Louisiana, in 

 sand, as Nereis gracilicirrala Warren, 1942, pp. 39-40, 

 from a name taken from manuscript. The species is not 

 known outside of the Gulf of Mexico and Florida Keys. 

 19. Nereis pelagica occidentalis Hartman, 1945. 



First described from Beaufort, North Carolina, by 

 Hartman, 1945, p. 20, pi. 4, figs. 1-6, and more widely 

 recorded from the Gulf of Mexico from southwestern 

 Florida to Louisiana, in sponge, oyster, and ascidian 

 masses, from pilings, and from sandy shoals, in httoral 

 zones. This may be the "Nereis pelagica" of Gary and 

 Spaulding, 1909, p. 9, which comes from among oyst«rs 

 in Louisiana. 

 *20. Nereis otigohalina (Rioja), new combination. 



Described as Neanthes oligohaiina Rioja, 1946, pp. 

 207-210, pi. 1, figs. 4-6, pi. 2, figs. 13-19, from Tecolutla, 

 Mexico, among roots of mangroves with barnacles. I 

 refer the species to the genus Nereis since the notopodia 

 have homogomph falcigers (Rioja, pi. 1, fig. 5). The 

 species may be the same as Nereis pelagica occidentalis, 

 above. 

 21. Nereis riisei Grube, 1856. 



Recorded by Augener, 1922, p. 42, from Veracruz, 

 Mexico, on corals and sponges. Elsewhere reported from 

 both sides of subtropical and tropical America.
