a ; but the worm is extremely small for dissection. The simple form 

 of the spermathecae does not appear to be due to immaturity ; 

 the clitellum is remarkably well defined and thick, and all the 

 other organs are present. 



The penial setae (fig, ^^) are "58 mm. in length, and approxi- 

 mately 3-5/. in thickness ; they are rather whip-like, — slender, 

 tapering gently, with pointed tip and rather wavy course ; they 

 are without ornamentation 



Remarks. — The present form shows resemblances to E. parva 

 (Fedarb), but differs in the absence of seminal vesicles in segment 

 xi, in possessing penial setae, and in the shape of the prostates 

 and narrowness of the prostatic ducts.
