CHARACTERS OF THE CEBRIONIDiE. 



Norwich, April 8, 1824. 

 Sir, 



An important error has crept into Dr. Leach's useful 



Monograph on the Cebrionidae in the Zoological Journal, which 



should not, I think, go uncorrected. The Family is stated to be 



Heteromerous, " Tarsi pedum anteriorum et mediorum, 5-articu- 



lati ; posteriorum, 4-articulati :" whereas it is Pentamerous, and 



the description should have been " Tarsi omues articulis quinque." 



I am, Sir, 



Yours very obediently, 



Thomas Brightwelx, F.L.S. 



J. G. Children, Esq.
