to the pillar. Only a few of the inner fibres cross in the middle line interiorly. The 
circular muscular coat is of considerable thickness, but the hypoderm is remarkably thin. 
The nerve-area is confined by these surroundings to a comparatively small oval tube 
presenting superiorly the two fibrous or firm pale central regions, and interiorly the 
neural canal and its granular coat. In the ganglionic parts the investment seems to be 
less complete, and a large opaque area exists superiorly. 
Dr. Baird does not give the dentition of his form, which was collected during the 
Australian expedition (before 1857 ?) by Dr. J. R, Elsey, but so far as the other features 
are described the specimens procured by the ChaUeuger seem to be identical. 
Eunice murrayi,^ n. sp. (PI. XXXIX. figs, 7, 8 ; (PI. XXa. figs, 19, 20). 
Habitat . — Dredged in Simon’s Bay, Cape of Good Hope, December 1873 ; depth, 
18 fathoms. 
A single example, measuring 38 mm. in length and having a breadth at the thick 
anterior part of about 4 '5 mm. was procured. 
The head (PI. XXXIX, fig. 7) is furnished with somewhat thick and very distinctly 
segmented tentacles, which, indeed, are 
almost moniliform. The median seems to 
be somewhat longer than the adjoining, but 
it is incomplete. The segments have con- 
siderable breadth, hence the term moniliform 
is appropriate. The palpi anteriorly are 
separated by a deep notch. The tentacular 
cirri just reach the anterior border of the 
buccal segment, and like the other cephalic 
processes possess long segments, only four 
being present. 
The dental apparatus is dull madder- 
brown, with boldly marked lighter touches.

a characteristic shape and are less rounded 
than usual. The left great dental plate has five teeth, the right six. The left lateral 
paired plate shows five teeth, the three inner being larger ; and only a single accessory 
plate with a short dental cone is appended on each side. There are six well-marked teeth
