ADDITION TO POLYCIIAETOUS ANNELIDS

The third parapodium (tig. 8) is noticeably heavier than is the 

 second. The notopodium is still a rounded knob with a tuft of 

 Ihread-like setae. The ventral cirrus is relatively shorter than it is 

 in parapodium 2. The dorsal cirrus widens suddenly from its attach- 

 ment to the cirrophore and narrows again to an apex from which 

 extends a finger-shaped process nearly as long as the basal portion.

Many of the setae are broken and some kinds occur on the second 

 specimen which I could not find on the type, hence the following de- 

 scription includes only those that were actually seen. Other forms 

 may have been lost and the distribution may not be accurately stated 

 owmg to losses in some somites. In anterior somites the notopodium 

 carries a tuft of very long and delicate setae most of which have 

 smooth margins but under high power (500 diameters) the larger 

 ones may be seen to have toward the apex very faintly indicated
