A HISTORY OF CORNWALL 



NEMERTINI 



The Nemertean worms have only received intermittent attention at Truro, so that the list 

 gives a very inadequate idea of the distribution of many of the species. A systematic account has 

 been kept of those found during dredging excursions in Falmouth Bay, but from Polperro, Mevagissey 

 and Gorran the records are fragmentary. Littoral species only have been obtained from Mount's 

 Bay, and Scilly is represented by a few specimens picked up casually during the summer of 1903. 

 The list is based on that published for the Plymouth district by Mr. J. H. Riches in the Journ. 

 Marine Biol. Assoc. vol. iii, and the nomenclature followed is chiefly that of Bilrger in Nemertinen 

 des Golfes von Neapo/, 1895.
