Among the above specimens were a few shorter and moi-e 

 stumpy forms that on microscopical examination proved to belong 

 to quite a different family. The specimens were few in number 

 and badly preserved. The diagnosis is based upon the anterior 

 end of the body, mainly because in both sexes the posterior end 

 was obscured and embedded in a thick brown prostatic secretion. 

 The males measure 11 mm. in length and the females 15 mm. in 

 length, and 0'46 mm. in breadth. They taper a little at either end.
