Genus Euborlasia. 



Body very thick, biconvex in section and usually not flattened 

 ventrally. Lateral margins absent after preservation. Head not 

 separated from the body. In animals not perfectly extended the 

 posterior part of the body is much thicker (3-6 times) than the anterior 

 region. Proboscis sheath short. Without eyes. 



1. Euborlasia spec. 



To this genus I refer two fragments of Nemerteans, which were 

 collected from a sandbank in the river Yealm. As in both fragments 

 the anterior portion of the body is wanting, I have not been able to 

 identify the species, or even the genus with certainty. One fragment 

 came living into my possession. It had been dug up in the sandbank, 

 high up the river Yealm, at a place where the water is nearly fresh. 

 A great deal of sand has been removed from this sandbank during the 

 last ten years, and it is now very muddy. This Nemertean, which was 

 formerly rather common at this place, has since become quite rare. 

 The other fragments, which also lack a head, were collected at the 

 same place in 1898. After preservation the body is deeply furrowed
