cirri missing. Acicula in all parapodia slender, distally knobbed. 



Superior simple seta slender, lightly serrate, minutely knobbed distally 



(Figure 30-38b). Composite falcigers bidentate, faintly serrate with 



basal serrations somewhat longer and coarser on some blades (Figure 30- 



38c, d), blade-length ratio 2-4:1. Pharynx extending to setigers 2-4. 



Proventricle extending from setigers 2-4 to 8, with 36-44 muscle cell 



rows. Dark band present on anterior end of intestine in paratype and 



one Gulf of Mexico specimen. Gametes present from setiger 8. 



REMARKS: S. f loridanus is newly reported from the Gulf of Mexico. Most 



specimens of the genus Syllides in BLM-MAFLA collections were originally 



referred to S^. japonica or S_. longocirrata , neither of which has been 



reported from the Gulf. 



PREVIOUSLY REPORTED HABITAT: 11 m; coarse calcareous sand. 



GULF OF MEXICO BLM-OCS OCCURRENCE: Three stations in northeastern Gulf 



(Figure 30-37); 20-43 m; coarse to medium sand. 



DISTRIBUTION: East coast of Florida, Gulf of Mexico.

MATERIAL EXAMINED: 

 Gulf of Mexico BLM-OCS: 

 MAFLA 2318K-11/77 (1 spec). 

 Supplementary Material: 



Florida--Hutchinson Island, St. Lucie County, 10.3 m, T. Perkins ID. 

 (FSBC I 23653, 1 paratype). 

 DESCRIPTION: 



Length, 1.9 mm (previously reported to 2.5 mm); width, 0.3 mm. Body 

 small, slender, complete with 24 setigers. Prostoraium rounded, with 

 four eyes, and two small ocular spots at base of palps (Figure 30-40a). 

 Antennae clavate; lateral antennae about two-thirds as long as median 

 antenna. Palps short, rounded. Nuchal organs as thin ridges between 

 prostomium and peristomium. Peristoraium inflated, with clavate tentacu- 

 lar cirri, dorsal ones about as long as lateral antennae. First pair of 

 dorsal cirri short, digitiform; second pair long, cirriform; following 

 pairs with 4-8 long, slender articles. Ventral cirri digitiform, ex- 

 tending beyond parapodia. Midventral anal cirrus present. Acicula 

 slender, slightly knobbed distally. Superior simple seta thick anteri- 

 orly, becoming slender posteriorly with acuminate tip and distal hood 

 (Figure 30-40b). Composite falcigers minutely bidentate; upper 1-2 

 falcigers spurred at base of blade (Figure 30-40c), lower setae faintly 

 serrate (Figure 30-40d) but not spurred; blade-length ratio, about 2:1. 

 Inferior simple seta slender, minutely bidentate (Figure 30-40e), pres- 

 ent on far posterior setigers. Pharynx extending to setiger 2. Proven- 

 tricle located in setigers 2-5, with about 28 muscle cell rows. 

 PREVIOUSLY REPORTED HABITAT: Low water to 11 m; sand, coarse calcareous 

 sand. 



GULF OF MEXICO BLM-OCS OCCURRENCE: One station off central Florida 

 (Figure 30-39); 20 m; medium sand.
