The resemblance of the buccal cavity and tentacles (cirri) of 

 Ammoccetes to the corresponding parts in Amphioxus is so close 

 that there can hardly be any doubt the two are homologous. The 

 anterior end of the nerve-tube of Amphioxus corresponds to the 

 lamina tenninalis of the craniate Vertebrates.
