266. A. cornuta. — The largest cellule of each group, with 

 a free margin, furnished with two setaceous appendages.

 but with a reference to Lamouroux only, by Mons. Deshayes 



* The numbers refer to his own list of species. 



f The number of Polyzoa described in this work is considerable, and it is 

 particularly useful for its Latin glossary. 



X I have figured here Busk's drawing of the cells of A. lendigera, from 

 which it would seem that the cells are grouped, and not a single series, as 

 represented by all previous observers. This fact should convince us that 

 unless we have the type specimens it will be impossible to identify any of the 

 old species. First of all the descriptions are too brief to be any guide ; 

 and, secondly, the imperfect microscopes of that time render the figures 

 untrustworthy. It is astonishing how one author follows another without 

 question. Cavolini, Esper, Blainville, and even Dr. Johnston, all copy the 

 figures of Ellis, which represent a single series of cells.
