Family AMPHINOMIDAE 

 Genus EURYTHOE Kinberg 



EURYTHOE COMPLANATA Pallas 



Aphrodita complanata Pallas, 1766, p. 109, pi. 8, figs. 1&-26. 



Seven specimens are in the collection from Pango Pango, Samoa, 

 •only one of which is well developed. This measures 85 mm. in 

 length and 7 mm. in greatest width. In the Japan collection is one 

 specimen conforming to the description of the species and, in a 

 separate bottle, a number of others in which no trace of eyes could 

 be seen. I have assumed that this loss is only apparent and due to 

 the preserving methods employed. 



It seems certain that some if not all of these are identical with 

 E. pacifica of Kinberg (1857, p. 14) but I have followed Chamberlin, 

 who (1919, pp. 28, 29) discusses the synonymy and concludes that 

 the following should all be grouped as complanata- E. paci-fica^ 

 kaTnahaTnecha, and corallina of Kinberg ; E. pacifica^ var. levuhaensis 

 oi Fischli ; and E. alcyonia of Gravier. 



Genus HERMODICE Kinberg 



HERMODICE PENNATA Treadwell, var. TUTUILENSIS, new variety 



Hermodice pennata Tkeadwell, 1906, p. 1165, fig. 41. 



The variety differs from the species in that the triangular median 

 portion of the caruncle is much smaller and neither pair of eyes is 

 obscured by the caruncle. The caruncle is much smaller in extent 

 than in the species, extending not quite to the posterior border of 

 the second setigerous somite. The outer and inner paired tentacles 

 are about equal in size and much smaller than the median unpaired, 

 the inner paired lying close to the anterior pair of eyes. The first 

 ventral cirrus is no longer than any others. In addition to the 

 longitudinal pink lines on the dorsal surface, a pinkish band sur- 

 rounds each notopodium at its base. 



Three specimens, one regenerating the anterior eight somites were 

 collected at Pango Pango, Samoa. The largest is 55 mm. long and 

 (not counting the parapodia) has a body width of 5 mm. 



Genus AMPHINOME Brugiere 



AMPHINOME ROSTRATA Kinberg 



Amphinome rostrata Kinberg, 1857 p. 12. 

 Chamberlin (1919 p. 27) lists this species as A. vagans Savigny 

 and gives the synonymy. I have followed Mcintosh (1885, pp. 21 to
