Cuticula finely annulate. The mouth leads into a vestibulum, 

 0*11 m.m. in length ; its entrance is armed with a dorsal and a

 shows, both above and below, three notches with papillae. The 

 oesophagus measures ^Vg of the entire length, and presents a spiral 

 musculature ; in a young worm of 14'6 mm. the nerve ring 

 surrounds the oesophagus 2-64 mm. from the head end, and at a 

 point situated 0*31 mm. behind it iim porus excretorius opens. 



The male (25 mm. long by 0*79 mm. broad) has a closely 

 involute tail,which resembles that of Spiroptera atrongxjlina, Rud.;
