In 1894 Pocock ("Diplopoda," in Weber, "Zoologische Ergebnisse einer 

 Reise in Niederlandisch Ost-Indien," vol. 3) modified his earlier system 

 by adding an order Limacomorpha and by recognizing five suborders under 

 the Helminthomorpha in place of his former two, these being the Callipo- 

 doidea, Colobognatha, Chordeumoidea, Juloidea, and Polydesmoidea. 



0. F. Cook, in 1895, dropping the Helminthomorpha of Pocock, gave the 

 Colobognatha a rank on a level with that of the Oniscomorpha and Lima- 

 comorpha. He placed the Stemmiulidae in a distinct order Monocheta and 

 likewise gave the Spirobolidae subordinal rank under a new order Anocheta. 

 To the Spirostreptidae he likewise gave subordinal rank under a new order 

 Diplocheta, under which he also at first placed the Juloidea and Cambaloidea. 

 Under still another new order, Merocheta, he originally placed the Lysio- 

 petaloidea, Craspedosomoidea, and Polydesmoidea. Later in the same year, 

 however, he contracted the Diplocheta by removing from it the Juloidea as 

 a new order Zygocheta, and also restricted the Merocheta by the transfer of 

 the Lysiopetaloidea and Craspedosomoidea to another new order, the Coelo- 

 cheta. His revised system of the Chilognatha, as far as the suborders he 

 thus recognized, was as follows : 



Subclass Chilognatha 

 Order Oniscomorpha 



Suborder Glomeroidea 



Suborder Zephronoidea 

 Order Limacomorpha 



Suborder Glomeridesmoidea 

 Order Colobognatha
