to PedicelUna by Van Beneden. Again, much as we regret to deprive 

 a lady of her well-earned honours, we are necessitated to point out that 

 the animal of which he gives an excellent figure and description, and 

 on which, supposing it to be new, he confers the name of Johnstonella 

 Catharina, was first described by Eschscholtz in 1825, uqder the 

 name of Tomopteris, afterwards by Quoy and Gaimard as Briarea ; 

 then by Busch in 1847 and by Grube iir 1848, as Tomopteris. It is 

 in fact the Tomopteris onisciformis, and has a very extensive distri- 

 bution, having been taken by the present writer in the tropical regions 

 of the South Pacific. It is assuredly an Annelid, but a most remark- 

 able form ; and a very excellent description of its structure, by Grube , 

 will be found in Miiller's ' Archiv' for 1848. 



Lapses of this kind will doubtless be corrected by our author in 

 his second edition, and we take leave of him with our best wishes 

 that he may soon have the opportunity of so doing.
