168 CIILOi;iA PARVA. 



to the 4tli segment, but it could not be very well maked 

 out, on account of the bad state of preservation of the 

 specimen. Each segment has on its dorsum in the middle 

 line a longitudinal dark violet stripe , and connected with 

 its hinder end there are two curved lines, like the arms 

 of an anchor, of the same colour; on the anterior seg- 

 ments these curved lines coalesce with the transverse band 

 in front of the bristle-papilla, which occurs also in Chi. 

 flava. Moreover there is a similarly coloured line behind 

 the bristle-papilla , from the base of each branchia to the 

 ventral fascicle. The dorsal cirrus is blackish and extends 

 beyond the bristle-tuft. The bristles of the dorsal fascicle 

 consist of a horny-yellow shaft and a transparent, vitreous 

 tip ; there is a boundary visible between these both divi- 

 sions , as if the tip was joined on the extremity of the 

 shaft. These bristles are furnished with fang-like serrations , 

 but they are not bifurcated ; only those of the anterior 

 segments are furnished with a small spur, but want the 

 teeth. The ventral bristles are slender, capillary, with short 

 bifurcated tip, agreeing with Baird's figure. 



Genus Wotopygos Grube.

I examined four examples of this species , one from Am- 

 boina , collected by Ludeking, and the three others belong- 

 ing to the Utrecht Museum ; of the latter the locality is 

 unknown. These specimens agree so well with Grube's des- 

 cription of N. crinita , that there can be no doubt in re- 

 gard to their connection with that species. As there however 

 rains a good deal of incertitude about the different species 

 of Notopygos and the allied genus Lirione , even about the 

 last genus itself, I will try to complete Grube's description 

 in some respects. 



The specimens measure respectively 50 , 30 and 25 mm.; 

 the number of segments is 29—30. The ultimate segment
