 remaining eight are arranged in submedian pairs. Each of 

 these pairs of papillge arises by the bifurcation of a common

 the tail is about 0'23 mm., and the posterior end is curled 

 ventrally. The mouth is minute and without lips. The 

 oesophagus is very slender and measures 1*55-1 'To mm. in
