16 PROCEEDINGS OF THE NATIONAL MUSEUM vol. C9 



Family HESIONIDAE 



Genus LEOCRATES Kinberg 



LEOCRATES IRIS Grube 



Leocrates iris Grube, 1878, pp. 105, 106. 



Nine specimens collected at Pango Pango, Samoa, and one at 

 Suva, Fiji. Grube described his species from a specimen collected 

 at Zamboanga in the Philippines but says that it occurs in Samoa. 

 Chamberlain (1919, p. 190) records one specimen from Papeete in 

 Ihe Society Islands. 



Family NEREIDAE 



Genus NEREIS Cuvier 



NEREIS (PLATYNEREIS) TONGATABENSIS Mcintosh 



Nereis tongatahuensis McIntosh, 1885, pp. 212 to 214, pi. 34, figs. 7, 8, 9; 

 pi. 16a, figs. 5, 6, 7. 



I have identified these on the basis of the body pigmentation, the 

 form of the prostomium, and the length of the tentacular cirri. 

 The first somites are not so narrow in comparison to later ones as 

 Mcintosh found in his material, but this may be a matter of preser- 

 vation. Mcintosh's figure 7, plate 34, shows a deep depression be- 

 tween the bases of the tentacles. In my material this is a definite 

 cut, the bases of the tentacles being completely separated as far 

 back as a line drawn horizontally across the middle of the two an- 

 terior eyes. In my specimens also, the parapodia do not modify 

 posteriorly as was the case with Mcintosh's but retain their sharp- 

 pointed lobes to the posterior end of the body. The setae agree 

 with those in Mcintosh's material. 



Collected at Pango Pango, Samoa. 



NEREIS PELAGICA Linnaeus 



Nereis pelayiea Linnaeus, 1767, p. 1086.— Ehleks, 1864 to 1868, pp. 511 to 



523, pi. 20, figs. 11 to 20.— V. Marenzellar, 1879, p. 14. 



V. Marenzellar's specimen is recorded as probably collected at 



Yokohama. I have doubtfully identified one very small individual 



collected at Peiyushan Light House by N. Gist Gee, as belonging to 



this species. 



NEREIS PUSILLA Moore 



Nereis pusilla Moore, 1903, pp. 428 to 429, pi. 24, figs. 25, 26, 27. 

 A single specimen, lacking color, except that in the posterior 

 somites the dorsal surface of each parapodium has a large dark 

 brown patch near the apex, and a much smaller one at the base.
