CHLOEFA FLAVA. 167 



Of this species our Museum possesses three specimens 

 from Japan , collected by von Siebold , one specimen from 

 Banka by Vosmaer; moreover I examined several fine spe- 

 cimens from the Utrecht Museum, The largest example 

 measures 130 mm. in length and has 41 segments; the 

 smallest one is 70 mm. long and has only 34 rings. 



They agree almost in all respects with M'Intosh's de- 

 tailed description. The breadth of the body and therefore 

 its more or less ovoid appearance however is not only de- 

 termined by the bristles , as suggested by M'Intosh , but 

 seems to be liable to some variation ; f. i. in a specimen 

 of 100 mm. the breadth amounts to 25 mm., whereas in 

 the smallest example it is only 14 mm. I found the un- 

 paired tentacle not longer than once and a half the length 

 of the pair in front of it. The dorsal bristles of the ante- 

 rior segments are furnished with a well-developed spur 

 and with 6 — 8 serrations along the opposite edge , but the 

 longer bristles of the middle and hinder end of the body , 

 in variance with M'Intosh's assertion , usually want this 

 spur totally and are only somewhat enlarged on that point ; 

 their tip is provided with large recurved fangs. 



Chloeia parva Baird. — Baird, loc. cit. p. 233, pi. IV, 

 figs. 8fl , h. 



Among the Amphinomidae of the Utrecht Museum I 

 met with an example, agreeing so much in several res- 

 pects with Baird's description of Chi. parva., that I believe 

 it to belong to the same species , though our specimen mea- 

 sures 90 mm. and is much larger than that of the British 

 Museum , the latter having only 1 inch in length. The shape of 

 the body is not ovoid, but elongate, narrower than in Chi. 

 flava Pall. ; its breadth in the middle of the body is only 

 12 mm. The bristles are also less developed than in the last- 

 named species, especially those of the dorsal fascicles. The 

 number of segments amounts to 36. The branchiae com- 

 mence on the 4tli body-ring ; they are violet , spotted with 

 black on the posterior side. The caruncle seems to extend
