EUROPEAN NEMERTEANS. 93 



NOTE XVII. 

 NEW SPECIES OF EUROPEAN NEMERTEANS. 



First Appendix to Note XLIV, Vol. I. 

 BY 



Dr. A. A. W. HUBRECHT. 



In the above-mentioned note , published six months 

 ago , several new species of Nemerteans were described 

 and at the same time an attempt was made to a classifi- 

 cation of the group, which should be in accordance with 

 the results arrived at through the comparative study of a 

 more extensive number of species and genera than had 

 been at the disposal of any of my predecessors. 



I am indebted for this plentiful supply of working-ma- 

 terial to the constant support of Prof. Ant. Dohrn and 

 liis assistants, and I feel especially obliged for their kind- 

 ness in forwarding to me — either alive or in excellent 

 state of preservation — further specimens for comparison 

 or determination ever since my departure from Naples. 



It is my intention to publish the descriptions of new 

 or interesting Nemerteans, which may come to my notice, 

 in the form of this first appendix , reserving the anatomi- 

 cal and histological results arrived at, for publication 

 elsewhere. 



The suborder of Palaeonemertini, which I establish- 

 ed for the genera : Carinella , Cephalotrix, Folia and Valen-
