A small Annelid of an oblong oval shape, with on cach segment s i x pairs of branchiae, 



divided in several filaments, tapering at the tip, except those of the median gill, that an- glo- 



bularly dilated near their extremity (sexual character?). The lateral dorsal cirrus situated between

<>f the region between the fust and the second branchia. Caruncle extendin;/ till the lïfth segment. 



At Stat. 115 and 313, on the reef, a small Euphrosyne was found, containing ripe uva. 

 The largest one nas an oblong oval body of about 11 mm. in length and 4 1 /., mm. in breadth; 

 its bare medio-dorsal held is rather narrow, about a fourth of the total breadth, and shows a 

 faint reticular appearahce. The number of its segments amounts to 22. 



The caruncle reaches the anterior part of the lifih segment and has a rather broad 



an ridge, that is longitudinally folded; its eyes are not very large and in front of the 



a short, thick, unpaired tentacle arises, twice as long as the eyes and tapering 



riorly, whereas the ventral ones are flanked bj a small antenna. There are two pyriform 



palp-plates in front of the mouth and its posterior border i, bounded by a cordate lobe, tolded 



itudinally and wedged into the fourth and fifth segment. Each parapodium carries a trans- 



roup of six branchial arbuscles (PI. I, fig. 7) dichotomously divided in filaments, 



ring at their distal extremity. except the median gill, the distal processes of which are
