Ovaries 
The ovaries in Hyalonemertes atlantica, which we now recog- 
nize as the female of Nectonemertes, are arranged in a single 
row along each ventrolateral border of the body in the immediate 
vicinity of the lateral nerves. Each ovary produces but one 
or two eggs of large size, as in other bathypelagic nemerteans. 
It is very evident that Verrill (92) saw and described these 
ovaries correctly as he did nearly all the organs that could be 
studied without the aid of sections. Unfortunately, however, 
this keenest of observers apparently made an error in transcribing 
his notes and placed the description of the ovaries of Hyalone- 
mertes in the diagnosis of Nectonemertes (p. 448). As his 
specimens of Nectonemertes are still available for study and show 
no such organs as he mentions, there is reasonable certainty that 
the explanation given is correct.
