six somites are deeply multi-ringed, 

 fectly smooth, so smooth 

 that no distinction is seen 

 between the respective so- 

 mites. The last few so- 

 mites of the tail are, how- 

 ever, separated by distinct 

 grooves. The nearest re- 

 lated species is F. sonorcE^ 

 but this latter species has 

 free spermathecas, while 

 in F. fuchsi the sperma- 

 thecae open into the intes- 

 tine. 



Chylus cells (p1. xvii, 

 fig. 2) .—These cells, wliich 

 occur in three somites 

 posterior to clitellum, are 

 long and narrow. The 

 inner duct is digitate at 

 the base. The chylus cells 



broad and shallow epithelial 

 cells. Spermatheca with a sac- 

 like apical pouch, without di- 

 verticles ; connects with the in- 

 testine, the stem of the sperma- 

 theca much twisted. Penial 

 bulb small, with cells opening 

 both into the sperm-duct and 

 at the base of the papilla. 

 Lymphocytes round, disc-like. 

 Nephridia with a long and nar- 

 row anteseptal. Color yellow- 

 ish-white. 



Locality. — Santa Cruz 

 Mountains near Boulder Creek, 

 on ranch of Mr. Koester, Prof. 

 Charles Fuchs. 



Characteristics . — Exteriorly 

 the species is readily distin- 

 guished. The anterior four to 

 while all those posterior are jDer-
