they open to ths s*nuo on the aedia side?? of the dorao-lotoral

disappears. 
At 6.X on, (Fig. ti) there is a slight epithelial* but not tubular,

rote of the gonad and a glomerulus of the eo^ono^hroo. the Uftlleriar 
ducts hare lu&ina thro- nout but sculler than the Wolffians, except 
at the anterior end. Posterior to the point of attachment of the 
round ligcnent the ducts enlarge greatly to the borne of the uterus, 
and are four to six tines as arge as in tha saloof the same oise. 
They arc beg lining to have the transferee portion sore mar ked and the 
left has more backward migration than the right. They unite to a
