Acetabulum median. Genital sinus 
median, immediately preacetabu- 
lar. Prostatic portion of vas 
deferens well developed, situated 
along right side of acetabulum; 
well-developed seminal vesicle post-

testis, ovoid in form; vitellaria 
arranged in numerous lobules in 
lateral fields, extending from post-
