136 LeodicidcE from Fiji mid Samoa. 



my specimens. Mcintosh figures the nuchal cirri as much shorter than in Ehlers's or 

 in mine, but his figure of the compound seta agrees with that of mine. Augener 

 records a specimen of this species from Samoa, in the collections of the Gbttingen 

 Museum, but gives no description of it. Fauvel describes the gills as longer than the 

 dorsal cirrus, while Crossland states that in spite of the large number of their branches, 

 the gills reallj' cover only a small portion of the dorsal surface. This agrees with my 

 specimens from Pago Pago.

Two individuals were collected in Pago Pago Harbor, in rock near the landing in 

 front of Cook's Hotel. In life they are brownish green in color, but rather translucent, 

 so that the contained blood modifies the tint very decidedly. The dorsal surface of 

 the prostomium is uncolored except for a purple band around the base of the median 

 tentacle and a similar one around the bases of the inner paired tentacles. From each 

 of these latter a band runs toward the median line, uniting with a broader greenish 

 band wliich runs toward the anterior margin. On either side of this stripe is a colorless 

 spot. The tentacles and all cirri are articulated, and on the tentacles and anal cirri, 

 but not on the dorsal, are brown bands in the constrictions. From the eighth somite 

 posteriorly a black spot is present in each somite near the dorso-lateral margin, and 

 the smaller of the two shows traces of dorsal white spots toward its posterior end. 

 None of the color remains in the preserved material. The animals are much more 

 active than is usual in this genus, squirming much as does Nereis when captured. 

 Crossland (pp. 313, 314) mentions the green color as an occasional variation, possibly in 

 relation to environment, and also comments on the activity of the animals when handled. 



The larger of the two specimens is 65 mm. long, and has a peristomial width of 1.5 

 nun. The other individual is about one-third smaller. The larger one contains 

 immature eggs, so m.ust be adult. The first gill, of 2 branches, is on the fourth seti- 

 gerous somite. The number of branches rises to 6 in the region of somites 15 to 20, 

 through the middle of the body it drops to 2, and at the extreme posterior end of the 

 body rises again to 4. Only the last 2 or 3 somites are free from gills. The jaws are 

 very delicate, only their margins colored. The proximal paired plates have 6 teeth 

 on the left and 8 on the right, the distal paired plates have 10 on the left and 8 on the 

 right, and the impaired has 9. 



The distinguishing features of this species are the articulated tentacles and cirri, 

 the median tentacle being long (in the larger of my two specimens it reached somite 8) ; 

 the peculiar arrangement of gills whereby the number of filaments decreases throughout 

 the middle of the body to increase again at the posterior end; and the fact that the 

 ventral acicula has a trifid apex. Crossland's text-figure 60 (p. 317) shows this arrange- 

 ment of gills, but the dorsal cirri are represented as non-articulated. As this is not in 

 agreement with figures 1 and 7 of his plate 22, it is probably an error in the drawing. 

 Fauvel (1919, p. 378) says that the tridentate aciculse are rare in specimens from Mada- 

 gascar, but thej' are mentioned as distinctive in his Australian specimens (Fauvel, 

 1917, p. 226, figs. 20a, 206), and they are present in my Samoan material.

Several specunens, none entire, were collected in Pago Pago Harbor, Samoa. 

 The general appearance of the animals would indicate that they are immature, but 

 the fact that several contain eggs indicates that they are adults. One individual
