* Mr. Brandt described the genus Splifcrotlicria a year before tlie figures of Zephronia were published in Grif- 

 lith's Aninuil Kingdom (see Ilecucil, p. 173), and bis 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.

% To retain the name of JDiplopoda 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. 



|| ft is vovy evident, as shown by M. Saussure, that Gervais was in error in placing the genus Oniscodcsmus in 

 the Glomeridao. It does not seem to me, however, that the Oniscodcsmid;c merit the rank of a family; the group 

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