Peribuccal ring resembling that of the preceding species, the lateral 
notches are however less deep and the lip-like chitinous projections from their 
centres are better developed and frequently almost triangular in shape (Text- 
fig. 3 A), in which case they have the appearance of lateral teeth. The dorsal 
and ventral teeth are notched so as to present two cusps (Text-fig. 3 B). 
Sub-median papillae small and rounded, lateral papillae were not seen. 
Female: 62-78mm. in length, maximum breadth of the body 05-0*68mm. 
The anterior region of the oesophagus measures 0*53-0*8 mm. in length, 
the posterior region 6*5-8 mm.

The posterior extremity of the loose caudal spiral terminates in a smooth 
knob, a pair of large lateral appendices are situated 0*1 mm. from the end of 
the body (Text-fig. 3C). 
Anus 0*4-0*48 mm. from the tip of the tail. 
Vulva 0*5-0*65 mm. from the anterior extremity. Eggs thin-shelled, 0*032- 
0*045mm. x 0*018-0*02 mm.
