Bosc quotes Bohadsch only ; his species must there- 

 fore be relegated to dona fascicularis or a near ally. 



The reference of Miiller's Ascidia corrugata to Ciona 

 intestinalis is open to doubt. 



The other references are probably correct. The 

 Ascidia viridescens of the ' Encyclopedic Methodique ' 

 is the " Sacanimal " of Dicquemare (1777). 



The title of a work given in Dryander's ' Catalogue

 duced on p. 8 on a reduced scale (fig. 27), clearly show. 

 They appear to be the earliest representations of the 

 anatomy of a Tunicate, and are remarkably accurate 

 for the time at which he wrote. Following the custom
