156 PROCEEDINGS OF THE NATIONAL MUSEUM vol. 83 



Proboscis with 20 bifurcated, terminal papillae; with 22 rows of 

 subtermiiial papillae, 4 or 5 in a row; a conspicuous, median dorsal 

 papilla exceeding the paired papillae in size. Proximal portion of 

 proboscis provided with well separated, minute, prickly cones. 



Kecurved cirrus first present from eighth or ninth setiger, increas- 

 ing in size from a minute, triangular lobe about as large as its dorsal 

 cirrus to a thickened, sickle-shaped cirrus (fig. 67, 6, c) at twentieth 

 s-etiger ; continuing large through median region ; decreasing gradually 

 in size in posterior fourth and present only as a minute knob on 

 twentieth last setiger (fig. 67, d) ; absent from more posterior segments. 



Parapodia as in figure 67, a-d\ acicular lobes strongly bilobed in 

 anteriormost segments (fig. 67, a, &), becoming only slightly bilobed in 

 median region (fig. 67, c), distinctly conical in posterior region (fig. 

 67, d). Setae of three kinds: (1) Barred setae in preacicular fascicles 

 of notopodia and neuropodia, (2) capillary setae, and (3) bristled 

 fetae in postacicular fascicles. Lyre setae not observed.

Dktrihutio7i. — Albatross station 3210 (1890) south of Alaska Penin- 

 sula, in 483 fathoms (type) ; station 4197 (1903), Gulf of Georgia, in 

 31-90 fathoms. Central California: Albatross station 3193 (1890) 

 dredged; station 3666 (1890) in 68 fathoms; station 3202 (1890) in

/Systematic position. — Nephtys punctata belongs to the iV. caeca 

 group. It is unique in the distribution of its recurved cirri (see 

 above), in the nature of its proboscis, and in having conical acicular 

 lobes in the posterior region.
