others have long projecting lobes. As Willey 

 (1905) and Potts (1909) have remarked, these 

 features are variable for the elytra may change 

 along the length of the body in a single speci- 

 men. For this reason, P. ctmndupliora is named 

 as a new species with hesitation. However, it 

 does not agree with the species described by 

 Fauvel (1923) from Europe, or those described 

 by Mcintosh (1885), Treadwell (1902), Augener 

 (1906), Hartman (1939), Hartman (1942b) or 

 Hartman (1965a) from the West Indies. The 

 presence of ctenidial flaps on the peduncle of 

 the median antenna of P. ctoiidophora appears 

 to be unique and the large pedunculate facial 

 tubercle has not been noted on any other species. 

 Recordti. — One specimen off Beaufort on rock 

 and sand in 20 m (*).

Records. — Several records between Cape Hat- 

 teras and Beaufort from the shore to 100 m 

 (5,7, 11, 13, 17, 18).

 and tropical seas: intertidal to 150 m.

Noteft. — Apart from the typical specimens of 

 S. limicola recorded above, 10 aberrant speci- 

 mens were obtained which are closer to S. nii)ior 

 Pruvot and Racovitza as described bv F'auvel 



(1923). In particular, there are no bipectinate 

 simple setae in the neuropodia. The anterior 

 elytra (Figure 2a) have no attached sand grains 

 but bear a few conical microtubercles on the 

 .surface and a few sim])le i)ai)illae on the external 

 margin. Posterior elytra (Figure 2b) have a 

 small excision on the external margin. The feet 

 (Figure 2c) and the compound neurosetae (Fig- 

 ure 2d, e) are identical with those of S. limicola. 



According to Fauvel, S. Diiiior lacks simple 

 bipectinate neurosetae and the excision in the 

 posterior elytra, both of which are character- 

 istic of S. li}»icola. More material is required 

 to decide whether these American specimens 

 represent a new species or whether S. mi}i(>r 

 is a synonym of S. li»ucola. 



Records. — Ten specimens off Beaufort in 

 20-80 m (*).

Holotijpc. — VSNM 43128; 9 paratypes,

Dc.'^criptioH. — Body up to 35 mm long with 

 about 60 .segments and uniformly pale in alcohol. 

 Prostomium (Figure 2g) rounded and without 

 eyes. Median antenna with a pair of small 

 bracts or ctenidia on ceratophore and an elon- 

 gated ceratostyle tapering to a slender terminal 

 filament. Lateral antennae not distinguished 

 but presumably fused to base of tentacular 

 segment which bears a ciliated cu.shion similar 

 to those on later notopodia. Superior tentacular 

 cirrus as long as median antenna but inferior 

 cirrus much shorter. Two setigerous lobes each 

 with a single terminal stylode. Palps mi.ssing 

 and their sheaths united to presetal bracts on 

 either side of mouth. 



Setiger 3 with a dorsal tubercle but no 

 dorsal cirrus. Elytra on segments 2, 4, 5, 7, 

 9 . . . , and alternate segments to 27th and all 

 subsequent segments. Small cirriform branchiae 

 on all elytrophores and dorsal tubercles from 

 segment 4. Elytra broadly oval (Figure 2f), 

 with few cushion-shaped papillae on surface, 

 and about 15 simple digitiform marginal papil- 

 lae; no external notch even on posterior elytra.
