Leodicidce from Fiji and Samoa. 143 



had the whole sixth somite (fourth setigerous?) uncolored, so he evidently found some 

 variations in this respect. Crossland's material was largely from the Maldives and 

 evidently showed a considerable range of variability in form and color, for he identi- 

 fied the species as coccinea, although some individuals showed as great a difference 

 from Grube's description as does my Samoan specimen. Since the Samoan material 

 agrees with Crossland's description, I have identified it as of this species. 



A single specimen was collected on Aua Reef in Pago Pago Harbor, Samoa. The 

 body is 230 mm. long and has a peristomial width of 3 mm. The gills begin on 

 somite 6 and extend over a distance of 40 mm. There are approximately 300 somites,

The general body-color is yellowish brown, somewhat lighter on the ventral surface, 

 but otherwise with no noticeable difference in the two areas. Numerous small yellow 

 spots are scattered over the entire dorsal surface. Toward the posterior end the 

 general color becomes lighter, with a decided pearly luster which is more prominent on 

 the ventral surface. A characteristic feature is an irregular banding and blotching of 

 the tentacles and cirri with a bro^ii pigment. On the tentacles there are several 

 (5 or 6) of these bands which seem to extend entirely around, with many other shorter 

 patches, which are very irregularly arranged. In alcoholic material the banding on 

 the tentacles remains, but that on the nuchal and dorsal cirri may disappear. The 

 pygidium and somites immediately in front of it have a decided purple color in alcohol. 

 Irregularly distributed colorless patches occur on the dorsal surface, these patches 

 being of various sizes. The fourth setigerous somite has a colorless dorsal band, which 

 varies in width in different individuals. The ventral surface of the prostomium and 

 peristomium are colorless, this appearing in a dorsal view as a whitish margin. 



A specimen 190 mm. long has about 250 somites and a peristomial width of 3 mm. 



The prostomium (plate 3, fig. 7) is 2-lobed, narrower than the peristomium. The 

 tentacles are rather short and thick, the median extending as far as the second somite, 

 the inner paired about as long as this, the outer paired shorter. The large eyes are in 

 the usual position. As stated above, the tentacles are banded with brown, with the 

 apices uncolored. The peristomium has straight margins, broadening at the anterior 

 end, forming rather a prominent lip. The distinction between the first and second 

 somites is most noticeable on the dorsal surface and is obscure elsewhere. The nuchal 

 cirri are situated at the very anterior end of somite 2 and extend only to a little over 

 half the length of the peristomium. They are slender and in life are banded with 

 brown. Somite 3 is about as long as somite 2 and there is very little change in diameter 

 until the extreme posterior end. * 



The apices of all parapodia are uncolored. The first has a very large dorsal cirrus, 

 into which extend two acicula> which are unusually large as compared with the needle- 

 like aciculae usually found in this position. The ventral cirrus is thick and heavy, 

 the setal portion very small. 



The tenth parapodium (plate 3, fig. 10) has a much greater dorso-ventral diameter, 

 the dorsal cirrus smaller than in the first and provided with three aciculse. The setal 

 portion has a presetal and postsetal lobe, the latter the longer, and the aciculse come 

 to the surface between them. The ventral cirrus is also smaller than in the first para- 

 podium, but is carried on the end of a rounded swelling, which gives it the general 

 appearance of being larger. 



A gilled parapodium (plate 3, fig. 13 of the sixtieth) shows a still greater reduction 

 of the cirri, the setal portion remaining about as before. Two relatively large aciculae 

 extend into the dorsal cirrus, and two especially large ones occur in the setal portion. 

 Toward the posterior end the parapodia (fig. 9, the twentieth from the pygidium) are 

 more nearly conical, the distinction between the anterior and posterior setal lips is 

 less marked, and the cirri are very small. There is one pair of stout anal cirri (plate 3,
