ON THE GENUS CHLOEIA. 178 
ones are about half as long as the unpaired, the inferior ones 
are much shorter. The first branchia lies upon Segment IV. 
The ventral bristles slender, with bifurcated tip; their short 
limb measures almost the half of the long one. The dorsal 
bristles of the 7th segment and of the following ones are 
only slightly stouter, with a blunt spur and with the long 
limb serrated along its exterior border. 
Chloeia conspicua, n. sp. 
2 spec. Sumatra, West-coast of Atjeh, depth of 6'/, fth. ; 
coll. by C. F. Kruisinga, Aug. 1893. 
1 spec. Sout-coast of Java, Dirk de Vries-bay, coll. by 
van Kampen, Dec. 1909. 
The length of the largest specimen 65 mm., its greatest 
breadth 13 mm.; the number of segments amounts to 37. 
Body more slender than that of Chl. flava, colourless 
except some distinct markings on the dorsum. Here each 
segment shows a violet longitudinal stripe, somewhat 
narrower in the middle of its length and interrupted in 
the intersegmental grooves. On both sides this stripe is 
accompanied with a >-shaped band, including thus a 
rhomboid area on the middle of the back, from which a 
dark band emerges, running along the anterior side of the 
parapodium. A similar band extends from the base of each 
branchia towards the dorsal cirrus. The dorsal cirri 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 over the middle of the caruncle, 
that extends till upon the 4th segment; the unpaired antenna 
violet, almost as long as the caruncle. The branchiae 
commence upon the 4th segment; the main stem and the 
branches are violet, the secondary pinnae ferrugineous. The 
bristles elongate, of a pale yellow-red colour in the Java- 
specimen; the ventral ones slender, bifurcated, with a short 
limb having more the character of a spine; the dorsal 
bristles of the 6th segment and of the following ones 
stouter, serrated, with a hardly visible spur.
