The pharynx is excessively folded. One may obtain an idea 
about it from Plate III, Fig. 7, which shows the pharynx partly 
protruded through the mouth. The large pharyngeal pocket has very 
deep and broad side-pockets, some of them being two-lobed. 
Male organization: The testes as well as the ovaries have 
the usual location. The male apparatus lies behind the pharyngeal 
pocket, not below as in Cryptophallus. Its distance to pharynx is

part of the body, demonstrating the location of genital apparatus in 
relation to pharynx and the posterior margin of the body. 9 x. 
nearly 2 mm., or more than twice the interdistance of the genital 
pores (text-fig. 24). There are two false seminal vesicles (text-fig. 
25) developed in the hindermost part of the great seminal canals. 
They are parallel to the prostatic vesicle and lie along the sides 
of this at about a distance double their thickness. Their muscula- 
ture is not very dense, and is about half the thickness of the 
ventral muscle wall of the body. The nuclei occur in and around 
the muscular envelope. Their stout elTerent duets run in transverse 
direction and open below the prostatic vesicle into the ductus 
ejaculatorius, provided with a moderately developed muscularis 
(text-fig. 26). 
The prostatic vesicle reaches a length of somewhat more than 
Vs mm. and has a club-like shape, with the swollen part at its 
proximal end. It does not take a vertical position as in Crypto¬ 
phallus, but, as in most Stylochids, is directed backwards, nearly 
parallel with the body-wall. Forming a compact „fret-work^ of 
interlacing fibres, its mmeularis is traversed to a great extent by 
broad gatherings of exits for the extracapsular prostatic giand cells 
(Plate IV, Fig. 29). The interior of the vesicle is lined with a low, 
8—12 i-L, normal epithelium, the cells of which are filled with a 
dense-looking protoplasma. There is a thick layer between the 
darkstained (with hematoxylin) epithelium and the muscularis. As 
in the preparation the traversing exits of giand cells are empty, the
