spinules; each spine (Figure 181) with an in- 

 wardly directed hook at its base. Seven thoracic 

 setigers. Thoracic membranes extending to end 

 of thorax. Bayonet-setae with a pair of smooth, 

 conical bosses at base of smooth blade. Thora- 

 cic uncinigerous rows black; individual uncini 

 with six or seven teeth. 



Rc))iarks. — H. i(iici)Hitu is distinguished from 

 H. ■pseudouncinata and H. gairacensis by the 

 simple points to the radii. Zibrowius (1970a: 

 693) reports that the worldwide records of 

 H. micinata are based on several closely allied 

 but distinct species. He regards Philippi's origi- 

 nal description of H. loicinata as insufficient 

 and feels the name should be dropped. These 

 specimens from North Carolina belong to a 

 group or possibly one species including H. 

 spongicola Benedict, H. elegantuhif; Bush, H. 

 decora Treadwell, and H. nlatnlateralia (Jones). 

 I do not have the specimens to sort out this 

 tangle. I report the name H. inici)iata and the 

 above description and leave other workers 

 with the necessary material to investigate 

 further.

Deso-iption. — -Tube adnate, with three ridges 

 including a low, regularly scalloped lateral pair. 



and a smooth median keel ; no transverse ridges 

 formed by earlier apertures. Body slender, 11 

 mm long, uniformly pale in alcohol. Branchial 

 crown (Figure 18j) formed by two slanting bran- 

 chial lobes each bearing seven radioles. Oper- 

 cular stalk formed from long and annulated 

 second dor.sal radiole; no wings. Operculum 

 (Figure 18k), fig-shaped with base soft, swollen, 

 and white; heavily chitinized distal part brown, 

 with a faint rim around truncate end; no internal 

 septa. Collar frilly and incised, forming paired 

 lateral lobes and a single ventral lobe; lateral 

 lobes continuous with wide thoracic membranes 

 to setiger 3 then abruptly narrowed but reaching 

 end of thorax. Collar setae as slender-winged 

 capillaries; noto.setae of setigers 2 to 7 with 

 many winged capillaries (Figure 181) and a few 

 "setae of Aponiatii.^" (Figure 18m) with most of 

 blade finely dentate. Thoracic uncini (Figure 

 18n,o) with a single or double row of 12 teeth 

 preceding the large truncate gouge. Abdominal 

 uncini (Figure 18q) with two or three rows of 

 10 teeth; abdominal capillaries (Figure 18p) 

 geniculate, with a tapering denticulate blade 

 almo.st at right angles to shaft. 



Ri )iiarks. — V. mnlticristatct is unusual in that 

 the opercular stalk replaces the second and 

 not the first radiole of the left branchial lobe, 

 further the opercular stalk is annulated and 

 the operculum itself lacks internal septa. Fur- 

 ther remarks will be found in Zibrowius (1968). 

 It will be noted that the tube described above 

 differs from that described by Zibrowius which 

 usually has five to seven dentate ridges. 



Records. — On corals in 18 m off Beaufort 

 (20, *). This is a new record for the United 

 States. 



Distrihiition. — Mediterranean and warm east- 

 ern Atlantic from the Bay of Biscay to Madeira, 

 Canary Islands, and Ghana; from shallow water 

 to 943 m.
