immature specimen which was sectioned longitudinally. First, the 
wall of the cirrus pouch thinned so rapidly toward the narrower 
extremity that it was quite lacking before the cirrus was reached. 
Second, the chamber holding the cirrus was contracted to very small 
dimensions, and quickly narrowed to a fine tube. 
Duff (p. 89), describes the testes as lobed, and so figures them in 
Fig. 1. In Fig. 4, however, she shows sections of branches , and my 
study of her microscopic preparations shows that they are really 
branched, as in my own material.

The female organs. The ovary is median or sub-median, dorsal, 
and contiguous to. the anterior portion of the acetabulum. Its zone 
does not extend anterior to the acetabular zone. It is subspherical, 
appears subtriangular posteriorly in cross section and subquadrilateral 
anteriorly; it measures 0-224 x 0-25 mm. and 0-35 mm. dorso-ventrally. 
The oviduct passes from its dorsal aspect approximately mesially and 
extends a short distance dorsally and posteriorly, where it effects a 
junction with Laurer’s canal, dorsal and close to the shell gland in the 
median line. It then makes three or four easy turns in this region and
