[Linnaeus defines Ascidia intestinaUs as " Ascidia 

 Isevis alba membranacea," a description which is 

 perhaps more applicable to Ciona pulchella than to C. 

 intestinaUs, and his references are : 



Bohads. mar. 132, t. 10, f. 4; Baster subsc. 2, p. 84, t. 10, 

 f. 5 ?; Act. nidros. 3, p. 81, t. 3, f. 3, 4. 



Bohadsch's Tetlti/umfasciculatum (t. 10, f. 4) closely 

 resembles Hancock's Ciona fascicular is. Copies of two 

 of his figures reduced in size are given on p. 6 (fig. 25), 

 the first being the one quoted by Linnaeus. Baster's 

 species (t. 10, f. 5) is usually referred to the Ascidia 

 ampulla of Bruguiere, and is most probably a Cynthia. 

 "Act. nidros." refers to Gunner's paper on Tethyum 

 sociabile. His figures (t. 3, ff. 3, 4) quoted by Linnaeus 

 are reproduced on p. 7 (fig. 26). It is very doubtful 

 whether they represent Ciona intestinaUs, and if they 

 do not, this species as now understood is not that to 

 which Linnseus gave the name intestinaUs, and most 

 of the earlier references on p. 9 under the name Ascidia 

 intestinaUs will fall. 



Miiller follows Linnaeus in his ' Prodromus,' but 

 omits the species, at least by this name, from the 

 ' Zoologia Danica.'
