The asymmetrical dorsal lobe is also large, measuring 0*27-0*32 mm. long by

that of its branches. 
Spicules, 0*6-0*65 mm. long, with barb-like projections posteriorly; the 
barb of the right spicule situated 0*09-0*1 mm., that of the left spicule, 
0*038-0*04 mm., from the posterior end (Text-fig. 1).
