PART I. 

 ON THE COLLECTION. 



The collection of Echiurids brought back from the Eastern Seas by Dr Willey was 

 small. It yielded but one species of Bonellia, the widely distributed B. viridis, and 

 four species of Thalassema. With the exception of Th. kokotoniense described by Fischer, 

 from the East Coast of Africa, all these had been before taken from neighbouring 

 Localities. 



In Part I. of the following article references to literature have been omitted, but 

 these are fully given in Part II. 



I. Genus. BONELLIA, Rolando. 



1. Bonellia viridis, Rolando. 



One small specimen, measuring 1"5 cm. in the body and 2 cm. in the proboscis, of 

 which the forked portions formed about 1 cm. 

 The hooks protruded very far.
