132 EUNlCiE. 



colour, unspotted, but margaritaceous. Head obtuse, rounded in 

 front. Antennae five, monilifonn, with a globular joint at the base, 

 setaceous, in proportions similar to E. Harassii, and nearly twice as 

 long as the post-occipital segment. The tentacula jointed, as long 

 as the transverse diameter of the segment. Branchiae commencing 

 on the third segment, and continued down the sides until near the 

 tail ; they are small, short, with about nine pectinations in their 

 fullest development. Segments narrow, divided by an impressed 

 suture ; the dorsum very smooth, iridescent ; and the ventral surface 

 is equally so, especially at the sutures. Anal segment with two elon- 

 gated submoniliform styles. Bristles, in their position, black. 



Obs. Of the size of the preceding, but more allied to E. anten- 

 nata. The antennae are so distinctly moniliform, that they resemble 

 those of a beetle, but the joints are uncertain in number. The 

 nuchal tentacula are also jointed, as well as all the dorsal cirri. The 

 segments are divided by deep sutures, smooth, unspotted ; and the 

 dorsal cirrus is shorter than one-half of the diameter of the segment. 



(a) Spinola. 



3. E. antennata, brownish, iridescent ; head bilobed in front ; an- 

 tennae moniliform ; cirri only less decidedly moniliform ; branchiae 

 commencing on the eighth segment, short, with about seven pecti- 

 nations at most ; dorsal and ventral cirrus reaching the apex of the 

 foot ; anal styles moniliform. Length 2-3".

Obs. The Museum specimen is in bad condition, but its identifi- 

 cation with Savigny's species cannot be doubted. The branchiae 

 rapidly develope themselves, the third or fourth pair being com- 

 plete ; and they continue thus on the twenty succeeding segments, 

 when they rapidly decline and disappear. The first segment is as 

 broad as the three following.

4. E. Harassii, vinous-brown, with a series of white spots down the 

 dorso-mesial line (one to every segment), and spots on the sides 

 and over the bases of the feet ; head bilobed ; antennae annulated ; 

 branchiae commencing on the sixth segment, with about eleven 

 pectinations where most developed ; dorsal cirrus not longer than
