Hartman (1965a: 178) described Iljipluu/its 

 octohnniclnis from slope depths off the coast 

 of New England which thus becomes DipUicir- 

 iiis iictnhrdiicliiis (Hartman). As Dr. Hartman 

 has ndted. it differs from D. atpi nsis in lacking 

 eyes antl in having neurosetae which taper 

 to fine tips instead of ending in minute booklets.

Flabelligera sp. 



R( iiKirks. — Over 36 post-larval specimens 

 3-4 mm long for 13-17 segments were obtained. 

 They all contain orange yolk granules in the 

 midgut. Most of the characters suggest Flalx l- 

 liflivii (iffiiiis Sars. Each neuropodium has a 

 single-jointed falcate hook and the surface is 

 tiabby with scattered groups of long club-shaped 

 papillae. The mucilaginous sheath has not de- 

 veloped and there is only a single arc of 8 -H 8 

 branchial filaments on each side of the cephalic 

 ridge.

 Description. — Holotype (Figure 14g), 12 mm 

 long for about 40 segments; maximum breadth 



2 mm. Surface with small, cylindrical papillae 

 and attached sand grains. Papillae (Figure 14h). 

 longer and less numerous dorsal ly, shorter and 

 more numerous ventrally. Cephalic cage well 

 developed but poorly defined. Setigers 1-3 with 

 barred capillaries in both rami, all directed for- 

 wards. Notopodia of subsequent segments 

 with three of four shorter barred capillaries 

 directed laterally. Neurosetae of setiger 4 (Fig- 

 ure 14j) still slender, barred, and directed for- 

 wai'ds but tips definitely curved; neurosetae of 

 setiger 5 as five short simple unidentate hooks; 

 following neui'osetae (Figiire 14i) similar, but 

 numbers decreasing to one on middle segments 

 and increasing again on "tail" segments. Buccal 

 apparatus including a bulbous lower lip, a pair 

 of stout grooved palps, a prostomial ridge with 

 four eyes, and a semicircular cephalic hood 

 with a single marginal arc of about 20 branchial 

 filaments of uniform thickness. 



RcDiarks. — The holotype is one of a few 

 specimens collected by Dr. L. McCloskey from 

 a coral head growing in 18 m off Beaufort. The 

 sandy crust on the dorsal surface of the body is 

 thin and quite different from the hard head 

 shield of Pli. parntata (Grube) or Ph. injiatu 

 (Treadwell) as redescribed by Hartman (1951). 

 Nonetheless there are several resemblances to 

 the latter species. The cephalic cage is similar 

 and in both, the first neuropodial hooks occur 

 on setiger 4. However, there are also important 

 differences. The thinner sandy crust has been 

 noted. The skin papillae are scattered and do 

 not form rings encircling the anterior margins 

 of the segments, as they do in Pit. inflata. The 

 latter species is also reported to have two sizes 

 of branchial filaments, 6 larger ones and 13 

 smaller. 



I believe Ph. ehlersi may well be the same as 

 some, but not all of the .specimens from Key 

 West described by Ehlers (1887) under the 

 name of Siphotuistdiii/i ni eariboidii Grube. All 

 the characters are the same except what Ehlers 

 terms the "Kiemfaden tragenden Blatte" here 

 termed the cephalic hood. Ehlers' description 

 and his figure of the branchial apparatus (pi. 

 42, Fig. 7) was based on "einem anderem" 

 specimen. It shows a tongue-shaped lobe with 

 numerous branchial filaments which is charac- 

 teristic of the genus Piruniis to which S. cari- 

 bottm has since been referred. However, other 

 species of Pironiis (including the type species
