Hah. Cape Grenville. (Che vert Exped.) 



2. — Amphinome pr^longa, sjp. nov. 



This large species is about six inches long and half an inch in 

 breadth, and the body contains forty-six segments, of quadrilateral 

 transverse section. The caruncle is very small, and not well- 

 preserved in the specimens. The tentacle, antennae, and palpi 

 are stout, dark-coloured, and sub-equal. The branchiae, which 

 begin on the third setiferous segment, are blackish, with lighter 

 grey stems, and very bushy and large. 



The dorsal setge are of two kinds : — those of the one variety 

 are long, and stout, and straight till near the extremity, when 

 they begin to taper, and end in a fine point, the terminal taper- 

 ing portion being gently curved ; those of the other variety are 

 shorter, straight, and pointed, and are beset by two rows of 

 minute teeth for some little distance below the apex. The 

 ventral setae, about a dozen in number in each foot, are long, 

 stout, and smooth, with a hooked extremity, closely resembling 

 in form the corresponding structure in the preceding species. 



Hab. Katow, New Guinea. (Chevert Exped.) 



3. — NoTOPYGOS FLAvus, sp. nov. 



This annelid is one inch in length, by two-and-a-half lines in 

 breadth, and consists of thirty segments. It is oval and flattened, 

 slightly pointed at both ends ; the posterior extremity being the 

 more acute. The caruncle is elongated and sinuous, extending 

 over five segments. The tentacle is longer than the antennae 

 and palpi. The branchiae, which begin on the fifth setiferous 

 segment, are small and ramose. The anal appendages are short, 

 club-shaped. The dorsal cirri are stout and short ; the ventral 

 about the same length, but more slender in form. 



The dorsal setae are of two kinds : — some are short, stout, and 

 simply pointed ; others are longer, and bifurcated at the extre- 

 mity ; the shorter branch being only about one-fourth of the 

 length of the other, and having a bluntish apex ; while the 

 longer branch is slightly bent outwards from the angle of the 

 fork, and is continued thence to its apex, without further curva-
