Leodicidw from Fiji and Samoa. 



137 



(in 3 pieces) measures altogether 50 mm. in length, has a prostomial width of \.lh mm., 

 and contains about 250 somites. The specific name is given because of the yellow 

 spotting which is common in Leodice, but the spots are unusually prominent in this 

 species. 



The general body-color of the anterior end is dark brown, darker on the prostomiura 

 than elsewhere and gradually lightening posteriorly, the color disappearing entirely 

 in the region of from somites 40 to 60. In the peristomium the color is continued on 

 to the ventral surface, but in all other parts it is limited to the dorsal. Scattered over 

 the surface of this browTi are numerous yellow dots. In the type a prominent un- 

 colored band extends along the median dorsal line of the prostomium and is continued 

 on to somite 2 (plate 2, fig. 1). Somites .3, 4, and 5 have each a prominent uncolored 

 spot toward the posterior dorsal border 

 and somite 6 is uncolored. In other 

 individuals the.se colorless spots are 

 either only faintly indicated or are 

 absent. Toward the posterior end of 

 the body each somite is marked by a 

 very narrow purple line across its poste- 

 rior dorsal margin. One specimen was 

 regenerating a pygidium which had one 

 pair of short, colorless anal cirri. The 

 tentacles are light brown except for the 

 apices, which are uncolored, as are the 

 nuchal and other cirri. 



The prostomium (plate 2, fig. 1) is 

 noticeably bifid, and when expanded is 

 a little wider than the peristomium. 

 The latter is a trifle wider than long and 

 slightlj' concave along the lateral mar- 

 gins. Somite 2 is about one-third as 

 long as 1 and sharply marked off from 

 it. The tentacles are shorter than 

 the peristomium, with inconspicuous 

 cirrophores, and the eyes are so sur- 

 rounded by pigment as to be scarcely 

 visible. The nuchal cin-i are slender 

 and much shorter than the peristomium. 



The first parapodium (plate 2, fig, 2) 

 has a bilobed setal portion, with heavj' 

 cirri, the ventral cirrus being especially 

 large. There is a single acicula, also 

 eleventh parapodium (plate 2, fig. 3)

needle aciculse in the dorsal cirrus. The 

 has a very prominent setal portion, with a 

 dense tuft of compound setae ventrally and a smaller tuft of simple setse dorsally. 

 There is a needle acicula in the dorsal cirrus. The dorsal cirrus is slender, but 

 the ventral one is short and thick and merges gradually into the ventral pad-like 

 swelling characteristic of the anterior parapodia in this genus, but especially prom- 

 inent here. A later parapodium from behind the middle of the body (plate 2, 

 fig. 4) has a conical setal portion with a prominent ventral swelling, carrying the short, 

 thick ventral cirrus on its outer end. The dorsal cirrus is very slender, and the gill 

 arises from the body-wall dorsal to its base. There is a single pointed acicula in the 

 middle of the setal lobe, and a hooked one near its ventral surface. A few small needle 

 aciculjE extend into the dorsal curus. 



In a small specimen the gills arise as a single filament on the thirteenth setigerous 

 somite and in the great majority of later somites there are two and three branches
