IDENTITY OF SOME MARINE ANNELIDS—HARTMAN 113 
Genus ETEONE Savigny 
ETEONE TRILINEATA Webster and Benedict 
FicureE 9, f, g 
Eteone trilineata WEBSTER and BENEDICT, 1887, p. 712 (U.S.N.M. No. 441; Hast- 
port, Maine). 
The prostomium is trapezoidal in outline, with a broad, shallow, 
median sulcus throughout its length. Dorsal cirri are thick, broadly 
rounded, as broad as long in median segments (fig. 9, g), somewhat 
longer than broad in posterior segments (fig. 9, f). Ventral cirri 
are longer than wide but never extend distally beyond the setigerous 
lobe; the superior acicular lobe exceeds in length the inferior acicular 
one. The two anal cirri are long, thick, about as originally shown. 
The setal shaft has a long tooth on one side and a shorter on the 
other. The specific name refers to three longitudinal color bands 
dorsally, consisting of a narrow median and a pair of broad, lateral 
ones. 
E. trilineata inhabits sandy mud or shelly bottoms, in the low 
intertidal zones or somewhat below. 
Family NEPHTYIDAE 
Genus NEPHTYS Cuvier 
NEPHTYS MACROURA Schmarda 
Figure 9, h 
Nephthys macroura SCHMARDA, 1861, p. 91. 
Nephthys circinata VERRILL, 1874, p. 88 (U.S.N.M. No. 15882; St. Georges Bank, 
Maine, in 85 fathoms). 
The recurved cirri are involute, present from the third setiger, 
continued nearly to the posterior end; the last five or six segments 
Jack them. The postacicular setae are long, silky, flowing, with few 
or no denticulations; preacicular setae are finer, barred. No lyre 
setae have been observed. A typical parapodium is shown in figure 
9, A. 
The resemblance between this and WV. macroura Schmarda (1861, 
p. 91) is sufficiently striking to suggest identity. Both have in- 
volute cirri, and the lobes on notopodia and neuropodia are the same 
except that V. circinata has a more pronounced supraacicular neuro- 
podial lobe. WV. macroura was originally described from New 
Zealand, but since it has been widely reported from southern and 
eastern South America as JV. praetiosa Kinberg (1865, p. 239), from 
La Plata as WV. virginis Kinberg (1866, p. 239), from southeastern 
South America, and as JV. dutrea Baird (1878, p. 95) from Patagonia. 
A subspecies, pervana Hartman (1940, p. 236), has been described
