similar in form to the preceding pair, but the dorsal a little longer 

 and narrower ; the third segment has one pair like those of the 

 preceding segment, and a small ventral cirrus similar to those of 

 the following segments, but no setse. 



The body contains about 270 segments, which are usually about 

 three times as broad as long. The dorsal cirri are phylloid, a little 

 broader towards the middle of the body than in front, the breadth 

 about twice the length, the length not equal to half the breadth 

 of the body, ovate, the free end gradually pointed. The parapodia 

 are bilobed, with' a phylloid ventral cirrus, armed with one stout 

 brown aciculum, and about thirty compound setse. The latter have 

 a slightly expanded distal end produced into a beak-like process, 

 with two or three short spines or teeth ; and a blade which is very 

 delicate, curved and tapering, lined on its concave border with a 

 row of very fine short cilia. 



Thei'e is an exsertile proboscis, the epithelium of which is green 

 and is produced into pyriform papilla;. 



The species was obtained with the dredge in Port Jackson. 



It is related to E. microceros of Claparede (1), but is distin- 

 guished from it by the presence of four eyes and by the dorsal 

 cirri of the second and third segments not being prolonged and but 

 little longer than the ventral.

The length of this species is three-quarters of an inch : the 

 breadth an eighth of an inch. The colour is dull yellow, with 

 narrow transverse bands of dark brown on each segment. 



The head is squarish, with a single, very short median tentacle, 

 and two lateral ones, the inner of which is situated at the 

 antero-lateral angle of the head, and is about twice the length of 

 the latter, while the outer is placed below the inner, and is about 

 half its length ; both are slender and unjointed. There are two
