ADDITION TO POLYCHAETOUS ANNELIDS 193 



these but are longer and more slender. They are faint straw color, 

 with slight darkening toward the ends and apparently have nor- 

 mally acute tips, though in all that I could find these were frayed. 

 (Fig. 19.) The uncinae of the thoracic tori (fig. 20), have 8 or 

 9 double rows of sharp hooklike teeth, of which the apical one is the 

 shiallest. Figure 20 is drawn in profile and shows only one row of 

 the teeth. The base of the uncinus is prolonged into a very slender 

 rod, whose length I was unable to determine with accuracy. It is 

 certainly many times as long as the uncinus itself. Ventral to the 

 torus is a tuft of fine setae of two sorts. One kind is long and 

 slender and tapers to a very acute apex. The other is larger though 

 still absolutely small and in the terminal one third of its exposed 

 portion has minute plate-like teeth in two rows, along the margin. 

 Similar fine setae occur in the seta tufts ventral to the tori carrying 

 the large setae.
