CHAETOPODA 



Except for a paper entitled ' Horae Zoologicae ' by R. Quiller Couch (Trans. Penz. Nat. 

 Hist, and Ant'tq. Sac. old series, i, 1845), and a section in Dr. Cocks's 'Fauna of Falmouth' 

 this important group seems to have been completely neglected by county naturalists. But for 

 the invaluable assistance given by Mr. H. Thomas, who took up the study of Cornish sea-worms 

 with extraordinary enthusiasm the county list would have been somewhat meagre both in species 

 and in details, for the help he gave went far beyond the records to which his name is attached.
