REPOET ON THE ANNELIDA.

This species agrees with the Eurythoe pacijica, Kinberg, as named by Prof. Grube 
in the Godeffroy Collection, except in slight particulars due to indifferent preservation and 
the wear of the bristles in the larger specimens. The same author, moreover, had under 
examination other examples from Tahiti and the Nicobar Islands.^ Some from Samoa 
measure about a foot in spirit. The same form was found by Prof. Percival Wright in 
the Seychelles, and it appears to be identical with the Amphinome hruguieresi of De 
Qnatrefages.^ The Eurythoe alcyonia of Savigny from the Eed Sea (Dr. Eiippell) is also 
closely allied, to judge from an example in the British Museum. The ventral bristles are 
smooth. A near form is the Amjohinome alba, Baird, the ventral bristles of which are 
mostly smooth, only one showing a serration. In the British Museum the Eurythoe 
[Amphinome) complanata from the West Indies seems to have the tip of the ventral 
bristles quite smooth. 
In the present state of our knowledge it is almost impossible to diagnose the forms 
referred to by the various authors, and it is probable that the same species has received 
several names. The laxity in this respect is shown by the fact that Kinberg in his 
description states that the ventral bristles are smooth, while his artist figures them with 
serrations. 
One of the Ceylonese individuals of Eurythoe pacijica in the British Museum shows a 
few notches in the ventral bristles towards the tip, but nO' distinct serrations.

Habitat. — Levnka, Fiji. 
The examples are small, the longest measuring about 18 mm., and the diameter of the 
fragmentary larger sj^ecimen being 3 mm. One has fifty segments. 
It is distinguished from the foregoing by the much more distinct segmentation, the 
rings being both larger and more deeply cut. The snout is more evidently bi-lobed, 
and the caruncle is proportionally broader, but it is doubtful how much reliance can be 
placed on spirit-preparations in this respect. The median tentacle is smaller than in either 
of the others. The eyes occupy the ordinary position, and are of a dull brown colour 
The anterior pair (as usual) are considerably larger. The caruncle impinges posteriorly 
on the fourth segment. Interiorly the mouth opens at the anterior border of the fourth 
body-segment, the three anterior somites sloj)ing oblicjuely from the sides inward. The 
median folds (prsestomium) show a distinct central hollow in front, though in this respect 
it agrees with the previous form. 
The only indication of branchiae on the first body-segment is an eminence at the 
base of the cirrus, but on the next is an inner tuft of two or three erect processes,
