This fine little Chloeia has first been collected by the Challenger-expedition near Banda 

 and is described by Mc Intosh, who had only a single badly preserved specimen at his disposal ; 

 his description therefore remained somewhat incomplete, but was afterwards accomplished by 

 Potts, who examined several specimens found near the Amirante-islands by the Percy Sladen 

 Trust-expedition. 



The length of the largest Siboga-specimen is 20 mm. ; the number of its segments amounts 

 to 25. The colour is usually pale brown, buff, in some specimens dusky brown as stated by 

 Mc Intosh, its palps being somewhat darker; examined however with the microscope this brown 

 appears to be stippled with small violet dots. Over the middle of the dorsum, in the space 

 between the branchiae, there occurs a pale band, in which a couple of longitudinal parallel lines 

 is situated next to one another (PI. VII, fig. 7); with the worms from the Amirante-islands these 

 stripes appear to be much thinner, whence may be concluded, that they perhaps represent a 

 variety. Also over the ventral middle there runs a pale stripe, in which lies a dark line, 

 that is continued along the internal side of both anal cirri. Moreover the anterior part of the 

 cephalic lobe has a dusky hue, like the two posterior antennae; also the caruncle does not 

 appear quite colourless, at least upon the lateral sides a number of pale, parallel transverse 

 stripes could be observed. External and parallel to the longitudinal stripes the dorsum bears a 

 row of orange-coloured crescentic markings, each of which is connected with a dark band running 

 over the front-side of the parapodium ; also the dorsal cirrus has a dark-violet colour, except 

 in its basal and distal part. The main stem of the gills is tinged with orange, their primary 

 branches with violet. Bristles with a yellow tinge. 



The caruncle, with a crest consisting of 1 6 lamellae or folds, extends till on the 4 ,h segment ; 

 in front of it arises the median tentacle, that is nearly of the same length or somewhat longer. 

 However in the young specimens (St. 66) it extends only to "/„ of the length of the caruncle. 

 The branchiae commence on the 5 th segment l ), whereas on the anterior four segments they 

 are replaced by a cirrus-like appendage (in figure 1 of PI. II of the Challenger-report, by a 

 mistake of the artist, the first branchia is placed on the 4* segment ; also in other regards 

 this figure is rather inaccurate, for the above-named cirrus-like appendages are wanting on the 

 anterior four segments and, as is rightly stated by Potts, the short anal cirri are figured as a 

 pair of long slender styles). Each gill has 7 to 8 alternating branches, more strongly developed 

 at one side than at the other ; the superior of these do not bear secundary pinnae. 



The bristles of the neuropodium emerge from a fissure-like groove, bounded by a pair 



1) Potts (loc. cit.) described from the western part of the Indian Ocean three other small Chlocia-species {Chloeia rosea, Chloeia 

 longisetosa and Chloeia maculata) nearly allied to Chl. fusca and having also the first gill on the fifth segment. It appears to me somewhat 

 doubtful whether his Chloeia maculata can be ranged among the genus Chloeia, because it has the ventral bristles and some dorsal ones 

 serrated along the inner edge of the loog limb; it also has the anal cirri rather longer than in the óther species.
