 P. pecUctditx, Krauss, P. Bronni, Dunker are synonyms.

 slaughter of species. I can oidy say that the admirable collection 

 before me fully justifies me.

First described t)y Lamarck under the name of P. BrasiUensvi, 

 a misnomer. Other synonyms are P. pigra, Forbes, Bucc. Iceviga- 

 tum, Wood, P. fulvu, A. Ad. I think that P. Nieobaricus, Zelebor
