PERCY SLADEN TEUST EXPEDITION. 



I wish to thank Mr. E. S. Goodrich, of Merton College, Oxford, for looking over this 

 rej^ort, and M. Robert Legros, to whose unique knowledge of the development of 

 Amphioxus and unvarying kindness in placing the same at my disposal I am very 

 greatly indebted. 



DISTRIBUTION. 



Of 187 specimens examined, 171 were assigned to Goldschmidt's species A. pelagicus, 

 only 14 being A. valdivice. The remaining two were the metamorphosed animals above 

 alluded to. 



The following Table, compiled by the aid of the list of stations given in Part I. of 

 these Reports, shows the localities from which the animals were obtained. A. valdivta 

 is indicated by round brackets enclosing the numerals, the metamorphosed animals by 

 square brackets.
