REMARKS: These specimens differ from Syllis ( Typosyllis ) lutea in 

 having the blades of the composite falcigers with knobbed terminal 

 teeth; smaller, rounded subterminal teeth; and finer serrations. S_. 

 (T.) cf. lutea was confused with several other species of Syllis in BLM- 

 OCS collections. 



PREVIOUSLY REPORTED HABITAT: Intertidal; on vermetid reefs, coral. 

 GULF OF MEXICO BLM-OCS OCCURRENCE: Scattered records in northeasten 

 Gulf (Figure 30-129); 10-87 m; coarse to fine sand, silty fine sand. 

 DISTRIBUTION: E. and W. African coasts, Suez Canal, Red Sea, Gulf of 

 Elat, ?Gulf of Mexico.

MATERIAL EXAMINED: 

 Gulf of Mexico BLM-OCS: 



MAFLA 2211 5-7/76 (1 spec, USNM 89884). 

 DESCRIPTION: 



Length, 2.3+ mm; width, 0.4 mm. Body slender; incomplete with 16 seti- 

 gers. Prostomium oval, with four lentigerous eyes, plus two ocular 

 spots at base of palps (Figure 30-132a). Median antenna with 20 arti- 

 cles, lateral antennae with 11-13 articles. Palps triangular, blunt. 

 Dorsal tentacular cirri with 20 articles, ventral ones with 11 articles. 

 Dorsal cirri with 18-27 articles anteriorly, 19-24 articles in midbody 

 region. Ventral cirri tapered, extending slightly beyond parapodia. 

 Composite falcigers bidentate with short serrations and small teeth 

 (Figure 30-132b-d). Blades of superior falcigers broadest subdistally 

 (Figure 30-132b) in anterior region. Blade-length ratios 1.5:1 ante- 

 riorly, 1:1 medially. Simple setae not observed. Pharynx extending to 

 setiger 9. Proventricle located in setigers 10-13, with 31 muscle cell 

 rows. Ventricle occupying two setigers. Pharynx 1.5 times length of 

 proventricle; proventricle 2.7 times longer than wide. 



REMARKS: Syllis ( Typosyllis ) sp. F was originally referred to S^. 

 corallicola Verrill, 1900, in BLM-MAFLA collections. It differs from 

 the latter in having a smaller body with much shorter dorsal cirri, and 

 anterior falcigers with shorter blades. 



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

 (Figure 30-131); 43 m; coarse sand.
