Eunice sp. 
From stations 4015 and 3822 were collected members of this genus, those from the former station 
too much injured for identification, the latter evidently an immature form. 
Genus LUMBRICONEREIS Blainville. 
Lumbriconereis grandis, new species. 
A rather large species, 3.5 mm. in diameter at the prostomium, 5 mm. at somite 35. No entire 
specimens were in the collection, but some fragments of the posterior end which were preserved were 
scarcely more than half as broad as the anterior portions. 
Head (fig. 52) bluntly rounded, length about equal to breadth. No eyes were visible. The head 
in each case was bent dorsally, owing to the position assumed by the animal when killed. When bent 
back to its proper position, there appears on either side a shallow depression at posterior edge of head. 
Lumbriconereis grandis, new species. (52) Head, x2.5. (53) Right maxillary apparatus, x9; ac, accessory plates. 
(54) Mandible, x9. (55) Seta, x!83. (56) Hooked seta, 183. 
In the jaw apparatus each lateral plate has 4 teeth (fig. 53); anteriorly on either side are two 
smaller plates, roughly triangular in form, with toothed apex pointing toward median line. The 
whole is surrounded by thin chitinous plate (not shown in figure) , in which at two points are seen 
darker patches (accessory plates, ac fig, 53). All mouth parts very dark brown, mandibles a very 
little lighter in color than maxillae, the two halves separated posteriorly for more than half their 
length. Anteriorly a wing of thin, transparent chitin surrounds the end of the mandible (fig. 54). 
Setae arranged in vertical rows in each parapodium. Base of seta dark brown, apex lighter, this 
difference in color very noticeable in entire annelid. 
Parapodium with anterior and posterior lobes, the posterior slightly the longer, and with a dorsal, 
acute tip; this structure less noticeable in anterior than in posterior somites. Toward posterior end 
whole parapodium becomes very prominent, and distinction between it and body is much sharper than 
anteriorly. Anterior and posterior lobes about as long as basal portion of parapodium. Setae of two
