anteriorly to the level of the eyes. The pharnyx is rather long, about 1/5 
body length, and its root is inserted at the beginning of the fourth fifth of 
the body. The copulatory apparatus is visible in the living specimen as a 
transparent area occupying the anterior half of the postpharyngeal 
region. 
Anatomy. — The two eyes are rather small, the diameters of their pig- 
ment cups measuring 26-37 /im. 
In the reproductive system, the two ovaries are situated behind the 
second or third lateral branches of the anterior intestinal trunk. Each 
ovary is equipped with a rather large, lobed parovarium, usually located 
laterally to the ovary. There are, however, cell accumulations also an- 
terior to the ovaries that histologically resemble parovaria without being 
connected with either the ovaries or the true parovaria. 
The numerous testes are essentially ventral, although at full maturity 
individual testicular follicles may extend almost to the dorsal body wall. 
They are arranged on either side of the body in a broad longitudinal zone 
beginning some distance behind the ovaries and terminating at the level 
of the pharyngeal root. In the region of the testes, the thin vas deferens or 
sperm duct on each side runs along the medial side of the ventral nerve 
cord, somewhat above the longitudinal layer of the ventral integumental
