small third tooth above two large ones. Dr. 

 Pettibone kindly .sent me a specimen of S. 

 iriglcyi from Massachusetts and this resolved 

 the discrepancy. The first few hooks on setigers 

 15-18 (Figure lOe) have a vertical series of three 

 teeth ; in the following segments the small upper- 

 most tooth becomes minute and in posterior 

 segments it is absent (Figure lOf). This has also 

 been noted by Foster (1971).

Spio cf. multioculata (Rioja, 1919) 



(?) Spid nniUioviiUitu. - Fauvel, 1927: 44, Fig. 

 15 h-o. 



Dcscriptidii. — Only two fragmentary speci- 

 mens, the larger 1.7 mm for 18 segments. No 

 color markings. Prostomium T-shaped with blunt 

 anterolateral projections; several eyespots; no 

 occipital papilla. Gills from setiger 1 to end of 

 fragment (setiger 18); all gills larger than noto- 

 podial lamellae and separated from them. Neuro- 

 podial lamellae broadly oval throughout. Only 

 capillary setae in notopodia. Neurosetae mainly 

 capillaries with .sabre-setae from 8th foot. No 

 hooded hooks before end of fragment. 



R< tiKU'ks. — So far as can be seen from these 

 small fragmentary specimens, the characters 



agree perfectly with those of S. nmltioculata. 

 The absence of neuropodial hooks is not sur- 

 prising as they do not occur on S. multioculata 

 before setiger 28-32. However this species has 

 not been recorded from the United States and 

 larger and better preserved specimens are re- 

 quired to confirm the record. 



Records. — Two specimens off Beaufort in 

 120 m (*). 



Disfrihufioii. — (of S. nmltioculata) Bay of 

 Biscay; intertidal.

Spio tilicoruis var. nov. Day, Field, and Mont- 

 gomery, 1971: 122. 



Description. — Body up to 11 mm long; head 

 (Figure 11a, b) and anterior segments flecked 

 with bi'own both doi'sally and ventrally. Pro- 

 stomium rounded in front and extending as a 

 blunt keel to setiger 2. Four subdermal eyes but 

 no occipital tentacle. Peristome broad and 

 partly fused to setiger 1. Setiger 1 with small 

 notopodial and neuropodial lobes and a large 

 gill. Subsequent parapodia (Figure lie) similar 

 but larger, each with a well-marked presetal 

 lobe, a short, blunt postsetal lobe and a large 

 .straplike gill arching over dorsum. Anterior gills 

 fused basally to jjostsetal lamellae but pos- 

 terior ones almost separate. Neuropodia with 

 small, oval postsetal lobes throughout. Noto- 

 setae as capillaries with finely punctate blades. 

 Anterior neurosetae similar but shorter. Hooded 

 hooks from setiger 11, six or seven per foot. 

 Anterior hooks bidentate (Figure lid), subse- 

 quent ones with superior tooth cleft forming 

 tridentate hooks. 



Remarks. — All the specimens from Beaufort 

 were broken with the largest anterior fragment 

 having 24 segments. They were orijtinally named 

 a new variety of S. ^tilico)-iiis and I am indebted 

 to Dr. Foster for informing me that she had 

 found the same form in the Gulf of Mexico and 

 named it S. (S.) pettihoncae. The description 

 given above is based on the Beaufort material 

 but it agrees with that of Foster (1971) with 

 two exceptions. My specimens, which were 

 presumably younger than those of Dr. Foster,
