Rh M. Gervais (Apteres, vol. iv), divides the Chilognatha into five families,—the, , , , and. Of these, the Polyxenidæ and Polydesmidæ are the same as the same-named families of Gray, whilst the Glomeridæ comprise the Glomeridæ and Zephroniidæ of that author, and the Iulidæ his Iulidæ and Craspedesomidæ.

The Polyzoniidæ are the Sugentia of Brandt. Thus:

M. Brandt (Recueil, p. 36), composes his "" (Chilognatha) of all the Diplopoda, except the Sugentia. This tribe he divides into three families,—,,. The first of these comprises the Polyxenidæ and Polydesmidæ of Gray; the second, the Iulidæ and Craspedesomidce; the third, the Glomeridæ and Zephroniidæ of that author. The Sugentia he divides into two sections, the and , which are respectively the Polyzoniidæ and Siphonophoridæ of Newport.

Mr. Newport (Linn. Trans., vol. xix), divides all the Chilognatha (including the Sugentia) into six families,—,, , , , . Of these, the Glomeridæ includes the Glomeridæ and Zephroniidæ of Gray; the Polydesmidæ the Polydesmidæ and perhaps the Craspedesomidæ of the same author; the Polyxenidæ and Iulidæ correspond to his families of the same name, whilst the Siphonophoridæ and Polyzoniidæ are the Sugentia of Brandt. Mr. Newport then associates these six families in three groups, which he calls tribes: 1st. ", Brandt," comprising the Glomeridæ. 2d. ", Brandt," comprising the Polyxenidæ and Polydesmidæ. 3. ", Newport," comprising the Iulidæ, Polyzoniidæ, and Siphonophoridæ.
