 intertidal to 7 m (3, 11. 13, 15. 18, 20).

a-e. 



Description. — Tentacular lobe collar-shaped, 

 with orange tentacles and numerous eyespots. 

 Buccal .segment (Figure 16a) with large, wing- 

 like lateral lobes united basal ly to form a sheath 

 at base of tentacles; second segment short 

 with rudimentary ventrolateral lobes; third .seg- 

 ment with large lateral lobes. Two pairs of 

 dendritically branched gills (one gill often miss- 

 ing). Smooth-tipped winged capillaries on 18 

 segments starting from segment 4. Rows of 

 avicular uncini from .segment 5. Uncini of first 

 and second rows (Figure 16b, c) with a long 

 neck below rostrum and base extending back 

 as a short, tapered shaft; uncini of subsequent 

 segments with shorter necks and without shafts. 



Remarks. — This species is close to Pista 

 palmata but the latter is reported to have the 

 lateral lobes of .segment 3 divided to form 

 tapered projections and the uncini of the first 

 row differ in shape. 



Reco)-ds. — Beaufort Sound between tide 

 marks and on coral in 18 m off Beaufort (20, *). 

 This is a new record for the United States. 



Distribution. — South and South West Africa; 

 intertidal to 20 m.

Loimia riridis Moore, 1903 



Ldimia riridis Moore, 190.3: 723, Fig. 11-14. - 

 Hartman, 1945: 46, pi. 10: Fig. 4. 5; 1951; 

 111. 



R( ma)-ks. — This species is closely related to 

 L. mednsa if not merely a variety of it. According 

 to Hartman (1945) "/.. riridis differs from 

 L. m( dnsa [see above] since it constructs mud- 

 covered tubes instead of coarse shell-covered 

 ones; ventral thoracic gland shields are notably 

 broader and thicker and uncini have teeth more 

 closely spaced." The uncini have six or seven 

 (or eight) teeth whereas there are four to six 

 in L. mednsa. 



R( cords. — Cape Hatteras to Beaufort, inter- 

 tidal (11, 13, 18). 



Dist)-Hintion. — Massachusetts to the Gulf of 

 Mexico; intertidal.

Desei-ij)tio}i. — Body markedly tapered. 100- 

 350 mm long, red when alive. Tentacular lobe 

 large and frilly, bearing numerous long con- 

 tractile tentacles. Normal gills absent but noto- 

 podia branched and vascular from about seg- 

 ment 9. Va.scular branches with small spinulose 

 capillaries at their ends. Posterior notopodia 

 not vascular and without notosetae. Neurosetae 

 absent. Ventrum glandular and midventral 

 pads greatly reduced. No tube.

 intertidal mudbanks and on coral at 6.5 m (3, 

 11, 13, 18,20, *).

 Carolina; intertidal to 6.5 m.
