subapical tooth reaching nearly to tip of apical tooth (Figure 28-34c), 



blade-length ratio 1.7-2.3:1. Neuroacicula black. Pygidium with thick 



glandular ring and two long, smooth anal cirri. Pharynx everted, with 



ciliated margin. Facial tubercle not observed. 



REMARKS: Hesione picta has been reported from the eastern Gulf of 



Mexico under various synonyms (see Perkins and Savage, 1975:28). The 



species is usually defined by its distinctive color markings. Since 



these preserved specimens lack pigmentation, they can only questionably 



be referred tojl. picta . 



PREVIOUSLY REPORTED HABITAT: Rocky habitats, coral reefs. 



GULF OF MEXICO BLM-OCS OCCURRENCE: Four records off western Florida 



(Figure 28-33); 14-58 m; coarse to fine-very fine sand, silty fine sand. 



DISTRIBUTION: Western Florida to Brazil in subtropical to tropical 



waters.

MATERIAL EXAMINED: 

 Gulf of Mexico BLM-OCS: 



MAFLA 2528G-6/75 (1 spec), 2528F-7/76 (1 spec, USNM 71781), 25281-9/77 

 (3 spec), 2640J-9/77 (1 spec). 

 DESCRIPTION: 



Length, 6.4+ mm (previously reported to 75 mm); width, to 1.2 mm. Body 

 fairly small, slender; all specimens incomplete with up to 20 setigers. 

 Prostoraium quadrangular, with two pairs of lentigerous eyes on posterior 

 half (Figure 28-36a). Lateral antennae slender, cirriform. Palps 

 slightly longer than antennae, with long bases and shorter styles. 

 Nuchal organs as slender ridges along postectal margins of prostoraium. 

 Tentacular and dorsal cirri long, distinctly articled distally. Para- 

 podia subbiramous, notopodia reduced to slender acicula supporting dor- 

 sal cirrophores, neuropodia well-developed with low, rounded pre- and 

 postsetal lobes (Figure 28-36b). Ventral cirri slender, cirriform. 

 Neuropodial falcigers with long extension of shaft-head entire; blades 

 long (Figure 28-36c) to short (Figure 28-36d), serrate basally, with 

 hooked tip and subapical sheath, blade-length ratio 3.7-6.3:1. Pharynx 



28-38
