distinct markings on the dorsum (PI. VII, fig. 5). Here each segment shows a violet longitudinal 

 stripe, somewhat narrower in the tniddle of its length and interrupted in the intersegmental grooves. 

 On both sides this stripe is accompanied by a >-shaped band, including thus a rhomboid area on the 

 middle of the back, from which laterally a dark band emerges, that runs along the anterior side 

 of the parapodium and the distal end of which becomes visible at the ventral side of some anterior 

 segments. A similar band extends from the base of each branchia towards the notopodium, and 

 another one over the frontal side of the neuropodium, just over the origin of the bristle-fascicle. 

 The dorsal cirri, posteriorly increasing in length, are dark violet except a short basal part, that 

 only is coloured at its anterior side ; the ventral cirri are colourless. An undulated dark stripe runs 

 over the middle of the caruncle, that extends till upon the 4 th segment. The unpaired antenna 

 violet, almost as long as the caruncle; the paired antennae colourless, the posterior ones reaching 

 to half the length of the caruncle, the anterior pair shorter. The anterior three segments with 

 a pair of cirrus-like, colourless branchiae; their notopodial cirri with a dark, dorsal stripe. The 

 branchiae commence upon the 4 th segment; their main stem and branches are violet, the 

 secondary pinnae ferrugineous. The palps with a dark line over their anterior part, just where 

 they are lying against one another; the margin of the mouth marked with small longitudinal stripes. 



The bristles elongate, of a pale yellow-red colour in the Java-specimen, in the specimens 

 from Atjeh golden-yellow. The ventral setae slender, bifurcated with a short limb having more 

 the charakter of a spine (PI. VIII, fig. 5); the dorsal bristles of the 6 th segment and those 

 of the following ones stouter, serrated, with a hardly visible spur (PI. VIII, fig. 4). 



This species is closely allied to Chl. parva ; however it could not be identified with one 

 of the known species of Chloeia.

The length of the largest specimen is 26 mm., its greatest breadth (without bristles) 

 7 mm.; the number of its segments amounts to 26. The smallest specimen measures only 16 mm. 

 The body is somewhat heavy, not tapering posteriorly, of a buff colour; the bristles are pale 

 yellow. The skin of the dorsum is wrinkled ; here each segment shows in the middle a violet 

 spot, somewhat resembling a roman amphora, surrounded by a white band (PI. VII, fig. 6). 

 Moreover in the anterior segment an oblique band is visible, running over the frontside of the 

 parapodium. A violet stripe runs over the middle of the caruncle; the labial folds are dusky. 

 The dorsal cirri are dark violet, the ventral ones colourless. The caruncle bears about 20 lateral 

 folds and extends till upon the anterior border of the 4" 1 segment. The unpaired antenna does 

 not reach the posterior end of the caruncle ; of the paired antennae the superior ones are about 

 half as lono- as the unpaired, the inferior ones are much shorter. The anal cirri are rather long,
