* Mr. Brandt described the genus Sphaerotberia a year before the figures of Zephronia were publisbed in Grif- 

 fith's Animal Kingdom (see Recueil, p. 173), and his name must stand for the genus. Moreover, the first 

 indication of the family by Mr. Gray, which I can find, is that given above, which is several years later than 

 that of Brandt.

J To retain the name of Diplopoda with such an entire alteration of its significance, as I was at first disposed 

 to do, would make a great deal of confusion, and there is really no principle of nomenclature or usage demanding 

 that it should be done. 



§ This family is inserted here, following Mr. Newport. 



|| It is very evident, as shown by M. Saussure, that Gervais was in error in placing the genus Oniscodesmus in 

 the Glonieridre. It does not seem to me, however, that the Oniscodesmidaa merit the rank of a family; the group 

 appears to be nothing more than a sub-family at most.
