pair slightly larger and farther apart (Figure 28-24a). Lateral anten- 

 nae long, cirriform. Palps similar in length to antennae, with bases 

 longer than styles. Nuchal organs as slender ridges along postectal 

 margins of prostomiura. Tentacular and dorsal cirri indistinctly arti- 

 cled distally. Parapodia with small notopodia, and well-developed neu- 

 ropodia having broadly triangular pre- and postsetal lobes (Figure 28- 

 24b). Ventral cirri slender, cirriform. Notopodia with slender acicula 

 anteriorly, acicula becoming gradually larger; stout, emergent, falcate 

 spine (Figure 28-24c) present starting on setigers 8-10. Neuropodial 

 falcigers with long extension of shaft-head bifid; blades minutely 

 serrate, with hooked tip and subapical sheath-like spine (Figure 28- 

 24d), blade-length ratio 2.0-5.2:1. Additional median acicular neuro- 

 seta (Figure 28-24e) present starting on setigers 4-6. Pharynx extend- 

 ing to setigers 4-9, margin surrounded by about 20 short fusiform papil- 

 lae. 



REMARKS: Hesiospina sp. A differs from H. similis (Hessle, 1925) from 

 Japan, in lacking notopodial spines anteriorly, and in having unidentate 

 rather than bidentate composite neurosetae. 



GULF OF MEXICO BLM-OCS OCCURRENCE: Scattered occurrences off western 

 Florida (Figure 28-23); moderate depths, 35-56 m; coarse to fine sand, 

 silty fine to very fine sand.
