spermatozoa in the prostate storage chamber (figs. 120 to 123). The yolk sacs are 

 frequently so large that they fill the larger part of the cffilomic cavity pressing 

 the intestine close up against the wall of body. 



Nephridia. The most anterior nephrostome is found in iii in front of septum 

 iii/iv. The most anterior nephropore is found in iv in front of the inner couple of 

 set.T. There are nephridia (pores) in iv, v, vi, vii and viii, while somites x, xi, xii 

 have no nejihridia. The neck of the nephrostome contains a large glandular swell- 

 ing, to which is attached muscles connecting with the septum. This neck is perforated 

 by several narrow ductules, which occasionally branch. The duct appears to con- 

 sist of a single tube not covered by peritoneal glands. On account of the rather mac- 

 erated condition of the si)ecimens I could not investigate the nepridial structure any 

 closer. 



Some of the specimens collected by my friend were from a new locality and 

 somewhat larger in size. This locality is Three Spring Meadow, on the east 

 side of the North Fork of Kings River, opposite the natural bridge, at an altitude of 

 about 8,000 or 9,000 feet, and several thousand feet above the river bottom at that 

 point. They were there found under some old logs lying across the meadow, and over 

 which the water was flowing, the worms being attached to the surface of the decayed 

 wood. These s|)ecimens were about ^ larger than those from the springs at Alpine 

 Meadows on the South Fork of Kings River several thousand feet higher up, but I 

 find no distinct characteristics, though the spermatheca appeared more twisted. 

 Among the specimens were a few of TehnatodrUus Vejdovshji, for which I am thus 

 able to note a new locality.
